There you have it

The first robot is connected to the sauerkraut! When we hooked it up it took a few minutes to charge, and then it moved. The current is very low so it doesn't move very much, but I have some theories about how to increase the current. Also, I noticed that the voltage coming from the sauerkraut dropped after a little while. Not sure why that happened. The voltage seemed to increase again when I wiggled the electrodes around.
