Instructions
Salvage radio-controlled car components for use in your toy robot. Find an RC car at a local toy store, or use an old one you have at home. An expensive model is not necessary in order to make a toy robot, so do not feel the need to purchase a high-priced RC car.
Set aside the remote control for the car. You will use this to operate the finished robot.
Working carefully, use pliers or a small hammer to crack and remove the plastic shell of the RC car. Discard the shell.
Now that the shell is gone, find and remove the necessary RC components for your toy robot. Gently remove the green rectangular receiver board and the black rectangular battery pack from the RC car. The two black circular devices with wires extending from them are the servos. Leave the servos in place; the base of the car will serve as the base for the robot.
Cut two pieces of Velcro into four distinct strips. Velcro consists of a "hooks" strip that connects into a "loops" strip when the two are pressed together. One hook and loops combination should be the same length and width as the battery pack, and the other should be the length and width of the receiver board.
Apply a thin layer of model glue to the back of each Velcro piece. The glue will add additional adhesive properties to the Velcro even if the pieces already feature a self-sticking back. Affix the receiver-sized "loops" piece of Velcro to the top center of the wheel base and the battery-sized "loops" piece to the bottom center of the base. Allow several minutes for the glue to dry.
Apply the receiver-sized "hooks" strip to bottom of the receiver board and the battery-sized "hooks" strip to the bottom of the battery pack.
Affix the receiver board to the top "loops" strip and the battery pack to the bottom "loops" strip on the wheel base.
Wire the components to the receiver board on the robot base. The battery pack features a two-wire lead that must run to an open insertion point on the end of the receiver board that is marked "Batt" (for battery). Insert the wires here. Additionally, each of the toy robot's servos must be wired into a separate insertion point on the end of the receiver board. Any insertion point besides the one set aside for the battery is allowed. You can apply a small square of duct tape or a dab of model glue to the wires to hold them in place against the end of the receiver.
Add optional design elements to the wheel base in order to build a toy robot. Attach decorative pieces with model glue.
Use the remote control to operate your new toy robot. If the controls fail, check the connections between the receiver board, the servos and the battery pack, and try again.
