Step 8: The legs
8 to 10 gauge will work too.
14 is the gauge ( the size, the diameter of the wire )
22 gauge is breadboard wire and gauge 0 is the size of your finger! 200 Amp
2 is the number of wire not counting the ground. You have a black and white wire.
The black wire is the "hot" that carry the 120V
14/3 is the same with one more wire. The wire is red. You normally use this wire when you have
a 3 way. Two switchs that control one light for example.
You can use a coat hanger to make the legs.
I recommend adding to some heatshrink to the end of the led to have better grip on the floor.
You can see on the video, the robot slips a little bit while walking on the table. There is no heatshrink on my robot, only rigid plastic tube.
