Steps
1
Cut 13 2.5 inch pieces of electric wire..
2
Strip about 1 cm off each end of the wire.
3
Thin the end of each wire with the soldering iron.
4
Solder each wire to the ends of the motors and the switches.
5
Solder a short piece of wire to the positive end of one side of the battery holder to make it 1.5V instead of 3V.
6
Glue the switches onto the battery holder in a A-shape so that the antennas cross. Make sure the short piece of wire you just glued on is in the front - this piece is known as the "third connection."
7
Glue the motors on the battery holder, but make sure they spin forward.
8
Make the third wheel in the back out of a paper clip and the pearl.
- Unwind the paperclip.
- Thread the paperclip through the bead to the middle of the paperclip.
- Fold the paperclip in half and glue to the robot so that the bead trails behind like a wheel.
9
Solder the wires together.
10
Take two small paperclips and bend them to form antennae.
11
Glue them to the metal part of the SPDT switches.
12
Attach the heat shrink to the motor shaft with a lighter.
13
Put in the AA batteries, and you are done!
