Locomotor Sub-functions for Control of Assistive Wearable Robots

Locomotor Sub-functions for Control of Assistive Wearable Robots

A primary goal of comparative biomechanics is to understand the fundamental physics of locomotion within an evolutionary context. Such an understanding of legged locomotion results in a transition from copying nature to borrowing strategies for interacting with the physical world regarding design and control of bio-inspired legged robots or robotic assistive devices. Inspired from nature, legge...

Locomotor sub-functions for design and control of locomotion

In this study we focus on bio-inspired legged locomotion concepts. A primary goal of comparative biomechanics is to understand the fundamental physics of locomotion within an evolutionary context. Such an understanding of legged locmotion results in a transition from copying nature to borrowing strategies for interacting with the physical world in design and control of bio-inspired legged robot...

Sparse control for high-DOF assistive robots

Human control of high degree-of-freedom robotic systems can often be difficult due to a sparse control problem. This problem relates to the disparity in the amount of information required by the robot’s control variables and the relatively small volume of information a human can specify. To address the sparse control problem, we propose the use of subspaces embedded within the pose space of a r...

A Novel Compact Torsional Spring for Series Elastic Actuators for Assistive Wearable Robots

The introduction of intrinsic compliance in the actuation system of assistive robots improves safety and dynamical adaptability. Furthermore, in the case of wearable robots for gait assistance, the exploitation of conservative compliant elements as energy buffers can mimic the intrinsic dynamical properties of legs during locomotion. However, commercially available compliant components do not g...
