Obstacle avoidance can be achieved as a secondary task by appropriate inverse kinematics (IK) resolution of redundant manipulators. Most prior literature requires the time-consuming determination of the closest point to the obstacle for every calculation step. Aiming at the relief of computational burden. this paper develops what is termed a backward quadratic search algorithm (BQSA) ... https://www.bekindtopets.com/limited-stock-Original-U-S-Vietnam-War-Era-Operation-Igloo-White-Seismic-Sensor-Inert-Rocket-great-price/
