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…
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…
A Bimodal Hydrostatic Actuator for Robotic Legs with Compliant Fast Motion and High Lifting Force
Alex Lecavalier, Jeff Denis, Jean-Sébastien Plante +1
Robotic legs have bimodal operations: swing phases when the leg needs to move quickly in the air (high-speed, low-force) and stance phases when the leg bears the weight of the syst…
Low-Level Force-Control of MR-Hydrostatic Actuators
Jeff Denis, Jean-Sebastien Plante, Alexandre Girard
Precise and high-fidelity force control is critical for new generations of robots that interact with humans and unknown environments. Mobile robots, such as wearable devices and le…
Multimodal Hydrostatic Actuators for Wearable Robots: A Preliminary Assessment of Mass-Saving and Energy-Efficiency Opportunities
Jeff Denis, Alex Lecavalier, Jean-Sebastien Plante +1
Wearable robots are limited by their actuators performances because they must bear the weight of their own power system and energy source. This paper explores the idea of leveragin…
A Lightweight Force-Controllable Wearable Arm Based on Magnetorheological-Hydrostatic Actuators
Catherine Véronneau, Jeff Denis, Louis-Philippe Lebel +3
Supernumerary Robotic Limbs (SRLs) are wearable robots augmenting human capabilities by acting as a co-worker, reaching objects, support human arms, etc. However, existing SRLs lac…
