A Two Degrees-of-Freedom Floor-Based Robot for Transfer and Rehabilitation Applications
Ian Lalonde, Jeff Denis, Mathieu Lamy +3
The ability to accomplish a sit-to-stand (STS) motion is key to increase functional mobility and reduce rehospitalization risks. While raising aid (transfer) devices and partial bo…
Theoretical Closed-loop Stability Bounds for Dynamical System Coupled with Diffusion Policies
Gabriel Lauzier, Alexandre Girard, François Ferland
Diffusion Policy has shown great performance in robotic manipulation tasks under stochastic perturbations, due to its ability to model multimodal action distributions. Nonetheless,…
Zero-Shot Policy Transfer in Reinforcement Learning using Buckingham's Pi Theorem
Francisco Pascoa, Ian Lalonde, Alexandre Girard
Reinforcement learning (RL) policies often fail to generalize to new robots, tasks, or environments with different physical parameters, a challenge that limits their real-world app…
Reconfigurable hydrostatics: Toward versatile and efficient load-bearing robotics
Jeff Denis, Frederic Laberge, Jean-Sebastien Plante +1
Wearable and legged robot designers face multiple challenges when choosing actuation. Traditional fully actuated designs using electric motors are multifunctional but oversized and…
A Dual-Motor Actuator for Ceiling Robots with High Force and High Speed Capabilities
Ian Lalonde, Jeff Denis, Mathieu Lamy +1
Patient transfer devices allow to move patients passively in hospitals and care centers. Instead of hoisting the patient, it would be beneficial in some cases to assist their movem…
Using Buckingham's Theorem for Multi-System Learning Transfer: a Case-study with 3 Vehicles Sharing a Database
William Therrien, Olivier Lecompte, Alexandre Girard
Many advanced driver assistance schemes or autonomous vehicle controllers are based on a motion model of the vehicle behavior, i.e., a function predicting how the vehicle will reac…
