#Robot stepper motor how to

To determine the size of the wheels, place the stepper motor on the round piece of wood shown in Picture 1 and measure the height from the floor. Because a 2-wheeled robot could end up toppling over forward or backward, I will attach a small ball caster to the back of the board for support. I’m thinking of using a round piece of wood as a base and attaching the stepper motors, the Arduino, and the battery to it.

Illustration 1 uses the free modeling software “123d design” and shows what I was thinking for a simple design for the 2 wheeled robot’s body. The parts for the 3D printer I used can be found here. Let’s measure the size of the stepper motors and other parts to be used and make a body that matches that size. This point, that basic motion control can be achieved very easily using two motors, is employed in many areas.

2 motors turning in the same direction gives a forward/backward motion and turning in opposite directions provides turning capability. A 2-wheeled robot can be made with a simple design if it has 2 motors. To start with, you need to think about the complete design for the 2-wheeled robot. Illustration 1 – Modeling a 2-wheeled robot L6470/42x34mm stepper motor screw set (available in Japanese).Make your own robot with this electronic construction recipe I’m going to make something with that kind of versatility. You often see robots that use this 2-wheel base as a source of locomotion. In this 2-wheeled robot, the forward/backward movement and turning can be accomplished with two motors placed side by side.

In the previous post, Use Arduino to control a motor – Making an RC car using a servo motor for the steering, we made a remote control car where a normal motor provides the forward/backward movement and a servomotor controlled the steering. This time, I am going to try building a 2-wheeled robot using stepper motors. Once you have learned the basics of using a stepper motor you can create some fun projects, and even make your own robot.
