Do It Yourself – Build A Robot

We have all faced various instances where we were prompted to build experiments whether for school, work or even your own pleasure. Believe it or not a robot can be very common in these situations. So in this how – to – guide we will explore the materials and steps required to build a robot.

How To Build A Robot

Required Tools

Shear

Required Materials

Wheel base

Nickel Cadmium battery

Receiver Combo (4 or 6 degrees of movement)

2 Velcro pieces

Professional Strength glue

2 Servos

Dual – lock tape

Instructions

1.Look around for any old toy parts that can be used, specifically old radio-controlled (RC) cars. These can be taken apart and the batteries, receivers, servos and more can all be used in your robot, saving you money. Also, think about stripping off the need less plastic pieces and leaving the wheel base of the RC car to make of.

2.Locate a wheel base (or strip down the existing RC car), not touching the wheel base. Put aside the other parts. Take two Velcro pieces and attach each to the wheel base using professional-strength glue, with one Velcro part on the rear of the base and one on the top.

3.Connect a nickel-cadmium battery to the bottom Velcro part, and then join a 4- or 6- way receiver to the top Velcro piece. The “ways,” or degrees, of the connecter refer to the level of movement it allows your robot. Ensure your receiver and controller can be used and give for the same amount of degrees of movement. A 4-way receiver makes way for up-down, left-right movement for example, while 6 ways makes way for more free diagonal movement, as well.

4.Attach two servos to your wheel bottom using dual-lock tape. Ensure the servos are found on the perimeter of the wheel base near the wheels, but on opposite sides of the bottom from one another.

5.Connect all your parts to the connecter. 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. Join the battery to the receiver, by using the channel marked “Batt” or “Battery.” Then, join the dual servos in directly adjacent channels on the receiver but away from the battery connection.

6.Power on your robot creation with your controller and give it a test run. You now have a functional robot. Add any decorative touches to your robot as you see fit.

Tips & Warnings

Finding the tool in a receiver might be tricky. Sometimes it appears like a little watch battery with two wires coming from it. It may also be cylindrical. But it will always be somewhat weighty compared to other components its size
