In
this picture, you can see some magnets embedded into the wooden panel. There are small pieces of metal on the scale model. The magnets are our version of the presets, having 6 magnet locations of the rack and one for transport mode. There is a physical barrier (small block of wood) that denotes the ground for tube pickup. There are youtube links in that picture thread.
Autonomous mode is on when the arm is "tucked away" under the robot, making all of the pots at their most extreme values.
We had an excellent freshman operating the arm. Best part of it? He understands every bit of programming behind it.
