In this task, we will design the chassis for the line following robot. There are several options available in terms of design tools for the design of the chassis. We chose Autodesk Inventor, but there are a lot of tools such as Autodesk 123D and so on.
The chassis for the robot is fabricated using the laser cutting technique. You are welcome to fabricate your own chassis. We have chosen to use laser cutting because it is the easiest to complete. The technique involves designing the chassis followed by preparing the design for fabrication and laser cutting.
You may download the design file available along with this project and use it for laser cutting. There is a trial version of Autodesk Inventor available for download and it can be installed and used for designing a custom chassis.
As a maker/hacker, it is important that you learn how to use these tools and how to design a chassis.
