The OI needs 100k pots. There are a variety out there, be sure to choose Linear or "B" taper. Mostly you will want to choose a pot for its mechanical configuration, electrically they are all (nominally) the same. (More expensive pots are more reliable and have a longer life, but the $1 "Alpha" brand pots at Mouser are OK too)

On the robot, try for 2.5 K or 5 K ohm pots, the RC reads those best.
