Designing the chassis for the line
following robot
In this task, we will design the chassis for the line following robot. There are several opions
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.
Prepare for lift off
The chassis for the robot is fabricated using the laser cuing technique. You are welcome to
fabricate your own chassis. We have chosen to use laser cuing because it is the easiest to
complete. The technique involves designing the chassis followed by preparing the design for
fabricaion and laser cuing.
You may download the design ile available along with this project and use it for laser cuing.
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.
The use of tools such as a laser cuter requires some basic training and
supervision. It is important that you undergo the requisite safety training
before operaing such equipment.
Engage thrusters
1.
We will begin by considering the components that go into the robot. The
components include the infrared sensors, a ball caster, two DC motors, the
Raspberry Pi, the Pi Plate, and the batery.
2.
Since the Pi Plate will be stacked on top of the Raspberry Pi, we will mount
the batery on a separate plate mounted on top of the Raspberry Pi. The
component posiions are designed based on intuiion. The chassis is shown
in the following image:
