Subsequently, during so-called smoothing, they seek to find a controller and system-specific trajectory that satisfies the dynamics and roughly follows the path computed previously =-=[11]-=-. As such, the actual path planning component is purely kinematic, with the system dynamics essentially being ignored during the planning stage. This has several negative consequences. Firstly, such s... |
