Robotic Test Tube Rearrangement Using Combined Reinforcement Learning and Motion Planning
Hao Chen, Weiwei Wan, Masaki Matsushita +2
A combined task-level reinforcement learning and motion planning framework is proposed in this paper to address a multi-class in-rack test tube rearrangement problem. At the task l…
Many-Objective-Optimized Semi-Automated Robotic Disassembly Sequences
Takuya Kiyokawa, Kensuke Harada, Weiwei Wan +3
This study tasckles the problem of many-objective sequence optimization for semi-automated robotic disassembly operations. To this end, we employ a many-objective genetic algorithm…
Implicit Contact-Rich Manipulation Planning for a Manipulator with Insufficient Payload
Kento Nakatsuru, Weiwei Wan, Kensuke Harada
This paper uses a mobile manipulator with a collaborative robotic arm to manipulate objects beyond the robot's maximum payload. It proposes a single-shot probabilistic roadmap-base…
Integrating a Manual Pipette into a Collaborative Robot Manipulator for Flexible Liquid Dispensing
Junbo Zhang, Weiwei Wan, Nobuyuki Tanaka +2
This paper presents a system integration approach for a 6-DoF (Degree of Freedom) collaborative robot to operate a pipette for liquid dispensing. Its technical development is three…
Robot Introspection via Wrench-based Action Grammars
Juan Rojas, Zhengjie Huang, Shuangqi Luo +3
Robotic failure is all too common in unstructured robot tasks. Despite well designed controllers, robots often fail due to unexpected events. How do robots measure unexpected event…
Assembly Sequence Planning for Motion Planning
Weiwei Wan, Kensuke Harada, Kazuyuki Nagata
This paper develops a planner to find an optimal assembly sequence to assemble several objects. The input to the planner is the mesh models of the objects, the relative poses betwe…
