Examining the physical and psychological effects of combining multimodal feedback with continuous control in prosthetic hands
Digby Chappell, Zeyu Yang, Angus B. Clark +6
Myoelectric prosthetic hands are typically controlled to move between discrete positions and do not provide sensory feedback to the user. In this work, we present and evaluate a cl…
Beyond Humanoid Prosthetic Hands: Modular Terminal Devices That Improve User Performance
Digby Chappell, Barry Mulvey, Shehara Perera +3
Despite decades of research and development, myoelectric prosthetic hands lack functionality and are often rejected by users. This lack in functionality can be partially attributed…
The Hydra Hand: A Mode-Switching Underactuated Gripper with Precision and Power Grasping Modes
Digby Chappell, Fernando Bello, Petar Kormushev +1
Human hands are able to grasp a wide range of object sizes, shapes, and weights, achieved via reshaping and altering their apparent grasping stiffness between compliant power and r…
Learning to Grasp Clothing Structural Regions for Garment Manipulation Tasks
Wei Chen, Dongmyoung Lee, Digby Chappell +1
When performing cloth-related tasks, such as garment hanging, it is often important to identify and grasp certain structural regions -- a shirt's collar as opposed to its sleeve, f…
When and Where to Step: Terrain-Aware Real-Time Footstep Location and Timing Optimization for Bipedal Robots
Ke Wang, Zhaoyang Jacopo Hu, Peter Tisnikar +3
Online footstep planning is essential for bipedal walking robots, allowing them to walk in the presence of disturbances and sensory noise. Most of the literature on the topic has f…
Immersive Demonstrations are the Key to Imitation Learning
Kelin Li, Digby Chappell, Nicolas Rojas
Achieving successful robotic manipulation is an essential step towards robots being widely used in industry and home settings. Recently, many learning-based methods have been propo…
Asynchronous Real-Time Optimization of Footstep Placement and Timing in Bipedal Walking Robots
Digby Chappell, Ke Wang, Petar Kormushev
Online footstep planning is essential for bipedal walking robots to be able to walk in the presence of disturbances. Until recently this has been achieved by only optimizing the pl…
