How to Build Your Own Robot

By Billy Kirk

Building a robot is not the insurmountable task you might think. When designing a robot, it is important to focus on making the project as simple as possible. A robot with advanced functions that can make you dinner and fetch your paper is nice, but it is best to start off with a basic, controllable design.

Things You'll Need

  • Wheel baseVelcro pieces (2)GlueNickel-cadmium batteryReceiver (4-way)Controller (4-way)Dual-lock tapeServos (2)Twisty tie

Step 1

Examine the parts you have on hand. Go through your garage and check your attic. Clear out the old toy box. Do you have some wheels or a base for your robot? Do you have a broken radio-controlled car sitting around? Robots that move on wheels tend to be the most durable.

Step 2

Take two pieces of velcro and use glue to affix them to the top and bottom of the base of your robot. This should be in the center of the base away from the perimeter and where the wheels are located.

Step 3

Place your nickel cadmium battery on the bottom of the base and affix it to the velcro.

Step 4

Attach the receiver to the top of the robot's base to the other piece of velcro. You will need a receiver and controller combo that is between 4- and 6-way. This refers to the degrees of movement that can be achieved by your robot via your remote control. A receiver and controller that can handle at least 4-way communication allow for movement left to right and up and down.

Step 5

Attach the servos to your wheel base with the dual-lock tape. The servos will power your robot, and using a dual setup with two servos is recommended. Attach each near opposite sides of the wheel base, near the wheels and edges.

Step 6

Wire the components to the receiver. This means the battery and both servos must be connected to the receiver. The receiver has channels on the end where the wires run from the servos. Just ensure that the two servos are attached side by side in the channels of the receiver, and that the battery is attached to the receiver on the opposite end of the servos.

Step 7

Clean up any loose or hanging wires. Use a twisty tie or some other mechanism to keep them from drooping out the bottom of the robot base.

Step 8

Consider adding your own decorative touches to your robot in an effort to personalize the frame. Attaching a weapon such as a battering ram by strapping it to the base or an "arm" will allow for its conversion into a battlebot.
