Things You'll Need:
- Wheel base
- Nickel cadmium battery
- Receiver/controller combo (4 or 6 degrees of movement)
- 2 Velcro pieces
- Professional strength glue
- 2 Servos
- Dual-lock tape
- Look around for any old toy parts that can be salvaged, specifically old radio-controlled (RC) cars. These can be stripped down and the batteries, receivers, servos and more can all be used in your robot, saving you money. Also, consider stripping off the unnecessary plastic pieces and leaving the wheel base of the RC car to build off of.
- Find a wheel base (or strip down the existing RC car), leaving only the wheel base. Put aside the other components. Take two Velcro pieces and attach each to the wheel base using professional-strength glue, with one Velcro piece on the bottom of the base and one on the top.
- Attach a nickel-cadmium battery to the bottom Velcro piece, and then attach a 4- or 6-way receiver to the top Velcro piece. The "ways," or degrees, of the receiver refer to the level of movement it allows your robot. Make sure your receiver and controller are compatible and provide for the same amount of degrees of movement. A 4-way receiver allows for up-down, left-right movement for example, while 6 ways allows for more free diagonal movement, as well.
- Attach two servos to your wheel base using dual-lock tape. Make sure the servos are located on the perimeter of the wheel base near the wheels, but on opposite sides of the base from one another.
- Wire all your components to the receiver. Glance at the receiver and examine the channels at the end of it. All your components will be wires into the ends of these channels. Connect the battery to the receiver, via the channel marked "Batt" or "Battery." Then, connect the dual servos in directly adjacent channels on the receiver but away from the battery connection.
- Turn on your robot creation with your controller and give it a test run. You now have a working robot. Add any decorative touches to your robot as you see fit.
