This paper develops a trajectory planning algorithm for a four-wheel-steering (4WS) vehicle based on vehicle kinematics. The flexibility offered by the steering is utilized fully in the trajectory planning. A two-part trajectory planning algorithm consists of the steering planning and velocity planning. The limits of vehicle mechanism and drive torque are taken into account. Simulation results ...

Abstract— In this paper, the trajectory planning of a two-link rehabilitation robot arm is addressed. Firstly, a Cartesian planning of the trajectory is defined to perform a proper motion exercise for the patient’s arm. Secondly, a trajectory planning in joint space is studied to obtain a similar Cartesian path with less computational complexity. The robot arm analyzed is the two degrees of fre...

The objective of this paper is to present a full-stack, real-time kinodynamic planning framework and demonstrate it on a quadrotor for collision avoidance. Specifically, the proposed framework utilizes an offlineonline computation paradigm, neighborhood classification through machine learning, sampling-based motion planning with an optimal control distance metric, and trajectory smoothing to ac...
