GRAINS: Proximity Sensing of Objects in Granular Materials
Zeqing Zhang, Ruixing Jia, Youcan Yan +5
Proximity sensing detects an object's presence without contact. However, research has rarely explored proximity sensing in granular materials (GM) due to GM's lack of visual and co…
Ray-based Interference Free Workspace Analysis and Path Planning for Cable-Driven Robots
Zeqing Zhang
This thesis studies the interference-free workspace (IFW) of arbitrary cable-driven robots (CDRs) for both cables and obstacles using the ray-based method. Continuing from this, th…
RDA: An Accelerated Collision Free Motion Planner for Autonomous Navigation in Cluttered Environments
Ruihua Han, Shuai Wang, Shuaijun Wang +5
Autonomous motion planning is challenging in multi-obstacle environments due to nonconvex collision avoidance constraints. Directly applying numerical solvers to these nonconvex fo…
A Generalized Continuous Collision Detection Framework of Polynomial Trajectory for Mobile Robots in Cluttered Environments
Zeqing Zhang, Yinqiang Zhang, Ruihua Han +2
In this paper, we introduce a generalized continuous collision detection (CCD) framework for the mobile robot along the polynomial trajectory in cluttered environments including va…
Reinforcement Learned Distributed Multi-Robot Navigation with Reciprocal Velocity Obstacle Shaped Rewards
Ruihua Han, Shengduo Chen, Shuaijun Wang +4
The challenges to solving the collision avoidance problem lie in adaptively choosing optimal robot velocities in complex scenarios full of interactive obstacles. In this paper, we…
