Collision avoidance maneuver design based on multi-objective optimization [PDF]

, 2014
The possibility of having collision between a satellite and a space debris or another satellite is becoming frequent. The amount of propellant is directly related to a satellite’s operational lifetime and revenue.

Nonholonomic stabilization with collision avoidance for mobile robots

, 2001
This paper presents a motion planner and nonholonomic controller for a mobile robot, with global collision avoidance and convergence properties. An appropriately designed (dipolar) potential field is combined with discontinuous state feedback.

Extensions to Reactive Self-Collision Avoidance for Torque and Position Controlled Humanoids [PDF]

, 2011
One of the fundamental demands on robotic systems is a safe interaction with their environment. For fulfilling that condition, both collisions with obstacles and the own structure have to be avoided.

Path design and receding horizon control for collision avoidance system of cars [PDF]

, 2006
The paper deals with path design and control realization problems of collision avoidance systems (CAS) of cars (ground vehicles). CAS emergency path design is based on the principle of elastic band with improved reaction forces for road borders and ...

Motion Planning for the On-orbit Grasping of a Non-cooperative Target Satellite with Collision Avoidance [PDF]

, 2010
A method for grasping a tumbling noncooperative target is presented, which is based on nonlinear optimization and collision avoidance. Motion constraints on the robot joints as well as on the end-effector forces are considered.
