How to design a Robot | Omnidirectional robot | Robot design


Robot design is an important process for making functional & creative robot. This is the tutorial about how to design a robot. A robot design project about omnidirectional robot. Robot design depends upon the features and working of the robot. Here we will make an omnidirectional robot design. We will discuss how to design a robot chassis.

01: Design a Robot Chassis

In this article, we will see how to design a robot chassis. Robot design depends on the required specification. If we are designing the chassis of Line following Robot our dimensions should not be much larger.

so we have some requirements about the size and dimensions. Mostly the small and smart sizes are preferred for making obstacle avoiding or line following robot. But if we are making something big. Like a Rescue robot the design will be much different either in look and in size as well.

Here we are making the design for Soccer playing Robot or you can say Pick and place robot. The robot can move  6-DOF.The Omni directional robot has the ability to move almost in all directions.

So here we will see the design of an Omni directional robot. The are two main types of material used for Robot kits.

  1. Acrylic sheets
  2. Aluminum sheets

02: Acrylic Sheet (base)

We can use other but these are the preferred materials. Acrylics sheets are nearly less costly as compared to aluminum sheets. We have to design the base of the robot from an acrylic sheet which is cut by using the laser cutting machine.

The shape of the base is a circle having the diameter of 250mm and the upper portion is about 230mm.The upper two wheels are at the angle of 35dergree from the center and the lower two wheels are at the angle of 45 degrees.

This design gives the drag to the robot when moving forward and also a movement in the respective angle. The thickness of the acrylic sheet is about 5mm we choose acrylic because it is light weight and its cutting is less expensive than the metal.

03: Aluminum Chassis

Aluminum is little costly than acrylic. We only use an aluminum base or complete chassis when we need strength. When we need a strong body that can carry high weight and could not damage by collision and hitting.

Below is the sketch Diagram of the Robot that I have designed for a Soccer Robot. The two plates of aluminum one are the base of the robot and other is the top cover. The diameter is 28 cm. These designs are made using SolidWorks.
