This paper describes the development of a scooter supporting the mobility of older people. The scooter is equipped with a drive assistance system and a special scooter navigation system. The drive assistance system consists of a velocity controller, a steering controller, and a collision avoidance system. In this paper it is demonstrated how the challenging control and steering tasks are modified to increase safety for older people. A special scooter navigation system is presented, to support elderly people in navigating on a safe route through the city using sidewalks, pedestrian lights and crosswalks. For extended positioning requirements a hybrid positioning system was developed combining GPS, WLAN, and inertial sensor data. By combination of these technical improvements it is demonstrated how older people are able to preserve their self-determined and independent life. Usability research was done with focus groups in order to become familiar with global user demands and expectations towards a mobility assistance system. Results show that the system components are expected to assist the user in navigation, steering and speed control rather than to take complete control on the driving situation.

ABSTRACTThere is increasing use of electric mobility-scooters by older people in South Australia, the fourth largest state in Australia. Although various issues about their use have been raised by users, carers, urban planners and legislators, to date they have received little research attention. The purpose of the study reported in this paper was to explore the factors that influence and impact upon older people who use mobility-scooters, particularly from their own perspectives. Data were collected through a survey of 67 current electric mobility-scooter older users, and through two focus groups with other older South Australian people who were users. The data showed that more than 71 per cent of the participants had owned their scooter for more than two years, most had purchased the scooter as new, and 80 per cent owned a four-wheel scooter. The scooter was used predominantly for getting to and from shops, visiting friends and family, and to go for rides. Most respondents used their scooters three to five times each week and travelled between two and five kilometres from their home. The key findings from the focus groups were categorised into three major themes of ‘obtaining a scooter’, ‘the meaning of mobility’ and ‘issues around sharing spaces’. Each is exemplified. The implications for environmental and building design, for the better training of users, and for public education are discussed.

In this study, we proposed an autonomous motion planning method for improving passenger comfort while ensuring safety, particularly with respect to mobility scooters used by elderly people. We proposed a trajectory planner for restricting vehicle behaviors with large accelerations and jerks by selecting a safe trajectory from a set of preset trajectories. Then, based on this trajectory planner, we developed an autonomous motion planning method with four different driving modes, and evaluated the effectiveness of the method through a numerical simulation. The simulation results demonstrated that the proposed method increased comfort without compromising on safety.

New, shared mobility modes, including dockless e-scooters and e-bikes, were recently introduced to many cities around the world. The aim of this article is to determine the differences between the users of e-bike sharing, and e-scooter sharing systems, and the characteristics of their travel behaviour. This study is based on the survey of the citizens of Tricity in northern Poland. We find that e-bicycles are predominantly used as first and last mile transport and to commute directly to various places of interest, whereas e-scooters are more often used for leisure rides. Survey respondents that adopted shared micromobility are generally young, and e-scooter users are on average younger than e-bike users. Although all shared vehicles in Tricity are electrically assisted, this did not allow for the elimination of the gender gap, or help retired and disabled people in the adoption of shared micromobility services. We have also identified factors discouraging people from the usage of e-bike and e-scooter sharing and found them to be different for both types of services. Finally, we investigated the issue of using shared e-bikes for urban logistics.

ObjectiveTo analyse injuries related to manual and electric scooter use from January 2016 up to and including July 2019.SettingElectric scooter rental services were launched in Denmark in January 2019. The services were provided by private companies. Although rules for handling and riding scooters have been established, no reports either before or after introduction of electric scooters anticipated the full extent of use, and injuries to riders and pedestrians.ParticipantsAll patient records mentioning manual or electric scooters. Records were reviewed, and data were stratified according to two groups: manual and electric scooters.InterventionsA predefined survey was completed in all cases where ‘scooter’ was present. This contained variables such as type of scooter, type of participant, mechanism of injury, acuity, intoxication, referral to treatment facility.Outcome measuresAmong incidents involving scooters, summary statistics on continuous and categorical variables of interest were reported.Results468 scooter-related injuries were recorded. We found that manual scooter riders were more likely to be children under the age of 15; fall alone—involving no other party; sustain contusions, sprains and lacerations; and bruise either their fingers or toes. Riders of electric scooters were likely to be 18–25 years, sustain facial bruising and lacerations requiring sutures, and be under the influence of alcohol or drugs. Non-riders of electric scooters were mostly elderly people who tripped over scooters, consequently sustaining moderate to severe injuries.ConclusionThere were two different types of population sustaining injuries from manual and electric scooters, respectively. The proportion of non-riders injured by electric scooters were surprisingly large (17%), and while electric scooters are here to stay, several apparently preventable injuries occur as a result of reckless driving and discarded electric scooters. Current rules for usage might not prevent unnecessary accidents and secure traffic safety and the lives of older individuals.

In this study, a test setup was designed for three- and/or four-wheeled electric mobility scooter models used by disabled or old people. This system is composed of a test platform that enables measurement of vehicular velocity, a data acquisition card, and an interface prepared in the C# program. Using the data acquisition card that was designed, seven quantities, namely, battery and motor currents, battery and motor terminal voltages, wheel speed in revolution per minute, and ambient and motor temperatures, were measured instantaneously during the test procedure and transferred to a computer via a USB device. Using these data that were transferred, motor speed in revolution per minute, torque generated by the motor, motor shaft power, motor and driver efficiency, instantaneous velocity of the vehicle, and total distance covered information obtained from the moment the vehicle began to be used were computed in real time throughout the experiment in the interface prepared in the C#, and their graphs were drawn and recorded. Thus, the faults in the battery, motor, or driver of electric mobility scooters became easily detectable in tests conducted under various conditions such as different ambient temperatures, different user weights, and roads with different slopes.

The ageing society has resulted in imbalances in the population age ratio. The ratio of working-age people was less than that of elderly people resulting in a shortage of elderly caregivers and increased healthcare costs. Although the lifestyle the elderly remains the same, their physical abilities are reduced, requiring them to rely on special equipment when traveling in order to gain more control and safety. Therefore, the Elderly Personal Mobility Device (EPMD) is developed using Internet of Things (IoT) technology to reduce the burden of caregivers, provide freedom and safety for elderly travelers, assess air pollution risks, and alert the occurrence of emergency events. The EPMD is designed in terms of structure, electrical equipment, and sensor systems. First, the shapes, sizes, and thicknesses of the carbon steel used for construction of the EPMD structure are calculated by using SolidWorks software. Next, the electric equipment is carefully selected to meet the requirements of actual use. Finally, the sensor system is designed to monitor the EPMD status and air quality using IoT devices to create a data interface and big data for elderly health service development, as well as an air quality map with distributed measuring stations and a charging station detection system for future use.

An electric wheelchair is the device to support the self-movement of the elderly and people with physical disabilities. In this paper, a prototype design of an electric wheelchair with a high level of mobility and safety is presented. The electric wheelchair has a high level of mobility by employing an omnidirectional mechanism. Large numbers of mechanisms have been developed to realize omnidirectional motion. However, they have various drawbacks such as a complicated mechanism and difficulty of employment for practical use. Although the ball wheel drive mechanism is simple, it realizes stable motion when negotiating a step, gap, or slope. The high level of mobility enhances the freedom of users while increasing the risk of collision with obstacles or walls. To prevent collisions with obstacles, some electric wheelchairs are equipped with infrared sensors, ultrasonic sensors, laser range finders, or machine vision. However, since these devices are expensive, it will be difficult for them to be widely used with electric wheelchairs. We have developed a prototype design of collision-detecting device with inexpensive sensors. This device detects the occurrence of collisions and can calculate the direction of the colliding object. A prototype has been developed to perform motion experiments and verify the accuracy of the device. The results of experiments are also presented in this paper.

Public transportation (PT) systems suffer from disutility compared to private transportation due to the inability to provide passengers with a door-to-door service, referred to as the first/last mile problem. Personal mobility devices (PMDs) are thought to improve PT service quality by closing this first/last mile gap. However, current PMDs are generally driven manually by the rider and require a learning phase for safe vehicle operation. Additionally, most PMDs require a standing riding position and are not easily accessible to elderly people or persons with disabilities. In this paper, the concept of an autonomously operating mobility device is introduced. The visionary concept is designed as an on-demand transportation service which transports people for short to medium distances and increases the accessibility to public transport. The device is envisioned to be operated as a larger fleet and does not belong to an individual person. The vehicle features an electric powertrain and a one-axle self-balancing design with a small footprint. It provides one seat for a passenger and a tilt mechanism that is designed to improve the ride comfort and safety at horizontal curves. An affordable 3D-camera system is used for autonomous localization and navigation. For the evaluation and demonstration of the concept, a functional prototype is implemented.

This chapter describes the mechanical design, manufacture and performance of a three-degree-of-freedom manipulator arm and gripper that can be attached to a mobile vehicle or electric scooter. Known by the acronym “ESRA”, or “Electric Scooter Robot Arm”, this device can be remotely or automatically controlled to pick up and retrieve heavy objects, such as books or grocery products, from high shelves or difficult-to-reach locations. Such tasks are often considered to be arduous or even impossible for the frail elderly and people with disabilities. This chapter describes one example of how the combination of mechanical and electronic engineering technology can be used to perform physically strenuous tasks and enable the frail elderly and people with disabilities to enjoy a greater degree of self-sufficiency, independence and physical productivity. It includes the design process for robotic arm manipulators and actuators. It also provides a brief overview of existing “state of the art” robotic and machine vision technologies, and how these can be used to perform many everyday domestic or household chores.

A design (sketch) of a prototype electric scooter adaptable to a wheelchair is proposed. A mechanism that allows adapting an electric power unit to a conventional wheelchair is presented. The aim of this design is to create an economic solution to motorize a wheelchair and support the independent mobility of wheelchair users. This is especially relevant as the number of wheelchair users is increasing. The device consists of a self-balancing scooter, serving as the power unit, which is replacing the main wheels of the wheelchair and a metal link, connecting it to the wheelchair. The steering is controlled with two sticks, which directly exerts pressure on the sensor pad and steering unit of the self-balancing scooter. By using a self-balancing scooter and hardware store materials the costs can be kept low and accessible to many people.

In the recent years, the focus of ever-progressing scientific and technological advancements is continuously drifting towards the rehabilitation engineering. The development in the field of “mobility aid” has led to research, which has transformed conventional manual attendant-style wheelchairs to electric-powered wheelchairs with improved control through joysticks, sensors and micro-controllers. Consumers with limited mobility (pain in legs, permanent injury etc.) and elderly users, who cannot independently operate a powered wheelchair due to their hands impairment, have to rely upon third-party assistance during transfers to secure their wheelchair. Most ‘Mobility Assistance Equipment’ manufacturers for the orthopaedically handicapped individuals have not been able to adequately address such problems. With mobility being a key factor in all aspects of human life, this project proposes a design to allow hands impaired people, who cannot walk to orient themselves in, and navigate through, complex environments with the help of foot controlled wheel chair. This paper presents design and development of a battery-powered wheelchair that will be operated by foot controls, based upon the need assessments of such consumers. The Electronic System is a basic speed control circuit designed and provides for four motion configurations — reverse, stop, slow, and fast.

Abstract People with disabilities often struggle with mobility issues, so there is a strong desire for devices such as powerchairs, which can provide more freedom. Currently, wheelchair demand in the US is increasing due to an upsurge in the elderly population. Often electric powerchairs suitable for outdoor use are extremely expensive, cannot be used indoors, and are not covered by medical insurance. In this project, these problems are addressed through the design of a chair which is suitable for both rough outdoor terrain and indoor use. This project is based on a request for a powerchair which our client’s son, who has cerebral palsy, can use on family trips in outdoor environments including grass, gravel, and sand. A photo of a previous nonfunctional prototype was provided to the team as a reference, and a full redesign was performed to resolve the problems identified. Before proceeding with the design, various sources were consulted to gain a thorough understanding of currently available technology and design methods. Many different adjustment methods and features were considered, including an adjustable frame, tracks, and a lifting system for curb mounting. The overall design selected is a welded sheet metal frame with wheels, and it was determined that the chair should have an adjustable wheelbase width to provide both outdoor stability and indoor maneuverability. Key considerations for the design include battery life, motor torque, maximum load, seat size, door width, and cost. The final specifications are based on the needs of the client, Kevin Sample, as well as an analysis of the wider consumer market. The width adjustment design uses an axle above the driving wheels, which are connected to it by sliding sleeves. Automatic adjustment is accomplished using a linear actuator. The drive wheels are large and run at low pressure to surmount obstacles and damp vibrations. Differential steering combined with rear caster wheels gives the chair a small turning radius, and its length is comparable to that of standard manual wheelchairs. The seat can be easily removed to access the battery and control system or to load the chair into a vehicle. A joystick is used to control the speed and direction of the chair, while a separate momentary switch is used for the linear actuator. Throughout the modeling process, stress analysis was performed using simulations in Inventor. Any necessary adjustments were made to ensure that none of the parts will fail, considering both failure theory and fatigue. Various grades of aluminum were selected for the majority of the manufactured parts, due to their corrosion resistance and light weight. The device is currently in the prototype manufacturing stage. If it is later marketed, a curb mounting device may also be included; this was decided against mainly due to cost and time restrictions. Space has also been left for a carrying basket, which will likely be added to the first prototype. The initial goal is to produce a single chair for our client, although the design may later be submitted for Medicare and ADA approval.
