COMBO-Grasp: Learning Constraint-Based Manipulation for Bimanual Occluded Grasping
Jun Yamada, Alexander L. Mitchell, Jack Collins +1
This paper addresses the challenge of occluded robot grasping, i.e. grasping in situations where the desired grasp poses are kinematically infeasible due to environmental constrain…

First Steps: Latent-Space Control with Semantic Constraints for Quadruped Locomotion
Alexander L. Mitchell, Martin Engelcke, Oiwi Parker Jones +5
Traditional approaches to quadruped control frequently employ simplified, hand-derived models. This significantly reduces the capability of the robot since its effective kinematic…

Guided Constrained Policy Optimization for Dynamic Quadrupedal Robot Locomotion
Siddhant Gangapurwala, Alexander Mitchell, Ioannis Havoutis
Deep reinforcement learning (RL) uses model-free techniques to optimize task-specific control policies. Despite having emerged as a promising approach for complex problems, RL is s…
