Повний текст джерелаInterventions focused on physical exercise help promote healthier aging. However, older adults' engagement in these programs remains relatively low due to environmental and personal barriers, such as limited access to infrastructure, mobility difficulties, or lack of motivation. To address these challenges, technologies like mobile robotic telepresence (MRP) can be used. Their integration into daily practice is still limited, and it is uncertain whether they will be well accepted by older adults or enable the feasibility of exercise programs. Acceptability, defined as the willingness to use a technology, is essential for the feasibility and effectiveness of interventions. The goal of this thesis was to evaluate the acceptability of the MRP Cutii® (CareClever) and then propose a remote exercise program for older adults.This thesis was carried out in collaboration with Cirris (Université Laval, Québec) and the HAVAE research unit (Université de Limoges, France). The project was approved by the ethics committee of the Centre intégré et universitaire de santé et des services sociaux de la Capitale-Nationale (# 2022-2449, RIS) (Québec, Canada). The MRP Cutii® used in these studies aims to break the social isolation of older adults. Designed as a mobile videoconferencing support, it allows remote, synchronous participation in physical exercise programs.Three studies are presented in this thesis. Based on the Unified Theory of Acceptance and Use of Technology-2 (UTAUT2), Study 1 evaluated the a priori acceptability of the MRP. Study 2 evaluated the situated acceptance of the MRP within the context of a remote intervention among two groups of individuals (autonomous or semi-autonomous). These two studies were conducted in Québec with participants aged over 65 living in private senior residences. A third study planned in France aimed to evaluate the equivalence of two groups concerning balance after completing an eight-week training program offered i) synchronously via MRP, ii) face-to-face. The bankruptcy of the CareClever company prevented its completion, and only its protocol is presented.The results of Study 1 (n=19) reveal that although participants responded positively to their first experience, their intention to use the MRP in the future remains low, highlighting a low a priori acceptability. Study 2 (n=21) confirmed these results after prolonged use (4 to 6 weeks), indicating low situated acceptance of the MRP. Reservations were expressed about the fit of the MRP with the needs of older adults, who seemed to prioritize functional over social assistance. The MRP appears to have limited advantages compared to other technologies. Using Thabane et al.’s (2010) criteria, Study 2 demonstrated the feasibility of the remote exercise program, emphasizing participant engagement and exercise safety. However, concerns about the usability and reliability of the MRP remain.This doctoral project evaluated the a priori acceptability and situated acceptance of the MRP Cutii® among older adults living in senior residences. Several barriers to the acceptability of the MRP were identified: the mismatch between the MRP’s objectives and the residents' needs, and unfavorable comparisons with other technologies. Nevertheless, evidence supports the feasibility of remote exercise programs offered via the MRP Cutii®. The effectiveness of the exercise program on physical condition remains to be assessed. Future research with larger and more diverse samples is needed to re-evaluate the constantly evolving technology and to measure the long-term engagement of older adults in exercise programs offered via the MRP

Повний текст джерелаIntervention robotics must meet the continuing need to go farther and faster. Within this framework, all-terrain mobile robots undergoing high velocities endure complex dynamic excitation including vibration, shock, impact and the resulting deterioration in quality of forces transmission in the wheel-ground contact that can lead to a loss of stability and hence undermine their mission. This thesis contributes to the development of control laws that ensure a robust path tracking besides a certain degree of stability (minimize the risk of rollover). In addition, the thesis proposes a new mechatronic device for active control of vehicle roll and increase the performance of mobility, and in particular its dynamic control during cornering. The control laws are developed based on physical models that take into account the vehicle dynamics and slippage phenomenon resulting from the wheel-terrain interaction. Validation and identification of these models are achieved from experimental results performed on the robot FAST-A (one of the two prototypes of the ANR-FAST project). These analytical models and experimental results are also compared to a complete 16 DOF numerical model, developed under the multi-body system environment MSC. ADAMS, in which the mechanisms of suspension, steering and traction, and the conditions of wheel-terrain contact are more accurately represented. The first control algorithm based on the LQR approach is used for the path-tracking problem. It considers a linear vehicle dynamics, and a linearized model of the kinematics of the robot in relation to its reference trajectory. The control algorithm is based on an optimization of tracking errors and system inputs. The performance of this control law is evaluated using the results from both the numerical simulation on MSC. ADAMS and the actual experience performed using the prototype. Furthermore, a comparison with another enhanced control law based on Model Predictive Control (MPC) techniques has been provided. This control technique has the ability to predict and anticipate future changes on the reference. The latter approach based on nonlinear continuous-time generalized predictive (NCGPC) proved to be more accurate in terms of path tracking and smother in terms of control signal. The applied method is also extended to any MIMO system with arbitrary numbers of inputs and outputs. Finally, a linear MPC is developed for the anti-roll device. This is based on an optimization on a finite time horizon of a certain criterion consists of a stability index and an index of energy consumption of the integrated device. The behaviour obtained is similar to the behaviour of a motorcycle rider who leans into the turn to counteract the centrifugal force. The lateral load transfer between the right and left wheel sides defines the stability index. Simulation results of this device are very promising with a remarkable reduction of the charge transfer of about 30%, thus increasing the safety of the device and finally a larger speed range (at a constant radius of curvature). The device in question is being assembled on the platform FAST-B (second prototype of ANR-FAST project) and will be tested during March and April 2012
