The Algorithm of Multiple Obstacle Avoidance Tasks for Dual-Arm Robots
IEEE Access, 2023 To achieve multiple obstacle avoidance tasks consisting of zero-space obstacle avoidance and terminal obstacle avoidance with self-avoidance permission, we propose an algorithm for multiple obstacle avoidance tasks for dual-arm robots. First, we design a

Avoiding moving obstacles [PDF]
Experimental Brain Research, 2008 To successfully move our hand to a target, we must consider how to get there without hitting surrounding objects. In a dynamic environment this involves being able to respond quickly when our relationship with surrounding objects changes. People adjust their hand movements with a latency of about 120 ms when the visually perceived position of their ...

Obstacle Avoidance via Hybrid Feedback [PDF]
IEEE Transactions on Automatic Control, 2022 In this paper we present a hybrid feedback approach to solve the navigation problem of a point mass in the n-dimensional space containing an arbitrary number of ellipsoidal shape obstacles. The proposed hybrid control algorithm guarantees both global asymptotic stabilization to a reference and avoidance of the obstacles.
