It allows user to find time-optimal smooth profiles for the joint variables while taking into account full capacities of the robotic system expressed by the maximum actuated joint velocities and accelerations. 2 Path Planning Path planning is a purely geometric matter, since it implies the generation of a geometric path without a specified time law, while the trajectory planning assigns a time law to the geometric path. Paths can be created that preserve straight-line path length, minimize flight time, or guarantee observation of a given area. Whereas Trajectory Generation would be the potential trajectories of a system, and when at rest would be zero. The trajectory planning tends to the mininum energy, which can be carried out by the examining the current consumption created in the other modules.

It is basically the movement of robots from point A to point B by avoiding obstacles over time. Such trajectories are obtained by limiting the actuator jerks required. This procedure neglects important influence factors, which have a significant impact on the spatiotemporal characteristics of the finally resulting motionsuch as the operator's physical conditions or the probabilistic nature of the human locomotor system. First, a sample-based trajectory planning algorithm is used to create a path between the UAV and the setpoint. Namely, the inertial forces (and torques), to which the robot is subjected, depend on the accelerations along the trajectory, while the vibrations of its mechanical structure are basically determined by the values of the jerk (i.e. Therefore, particular care should be put in generating a trajectory that could be executed at high speed, but at the same time harmless for the robot, in terms of avoiding excessive accelerations of the actuators and vibrations of the mechanical structure.
