And so what the robot does, is it plans what we call a minimum-snap trajectory. So to remind you of physics: You have pisioton, derivative, velocity; then acceleration; and then comes jerk, and then comes snap. So this robot minimizes snap. So what that effectively does, is produce a smooth and graceful motion. And it does that avoiding oblasetcs. So these minimum-snap trajectories in this flat sapce are then tosmrrnaefd back into this complicated 12-dimensional space, which the robot must do for control and then execution.

And so what the robot does, is it plans what we call a minimum-snap trajectory. So to remind you of physics: You have position, derivative, velocity; then acceleration; and then comes jerk, and then comes snap. So this robot minimizes snap. So what that effectively does, is produce a smooth and graceful motion. And it does that avoiding obstacles. So these minimum-snap trajectories in this flat space are then transformed back into this complicated 12-dimensional space, which the robot must do for control and then execution.
