It is good. I had the good fortune at CMU of showing Shannon how to use a joystick to control a 3D pogo stick (Designed my Marc Raibert of future Boston Dynamics fame; I did the EE & SW) This shows the robot and me driving; unfortunately, we have no video of Shannon 'driving' the machine, but I can tell you the smile on his face was ear-to-ear. https://youtu.be/Bd5iEke6UlE
