To meet the requirements on funko dab rig industrial robots concerning their fast-moving pick-and-place or obstacle avoidance, this article puts forward a novel high-speed and smooth transfer control algorithm for spatial elliptic trajectory - an modified S-shaped acceleration/deceleration (ACC/DEC) control algorithm based on a piecewise continuous jerk curve in order to achieve the smooth motion at a high speed.Through mathematical modeling and interpolation point algorithm of spatial elliptic trajectory, the interpolation point information can be obtained.Then, using the speed look-ahead algorithm, the optimal speed at the switching point can be calculated during the trajectory transfer.

According to the analysis on the experiment and simulation results of a sorting case, the velocity curve turned out to be smoother and the run time decreased by 33.69%.In this way, this transfer algorithm can guarantee the smooth motion of industrial hamamelis crema robots and also improve the motion efficiency significantly.
