Robot Buggy Components are mounted on a base and wired to the controller. There are options for this with your own kit that we review here.
The introductory project site from which we’ve drawn ideas has guidance for constructing the most basic of chassis from a cardboard box.
The RabbitHole offers some design options here for a more rugged buggy built on a plastic plate, including discussion of how that design could be extended using CAD/CAM prototyping.
Solid-Plate Chassis Design
Components selected or produced for our prototype are shown in the gallery and listed here:
- Plastic Chassis Baseplate and Mezzanine – these are bespoke designs cut and drilled for the motor and remaining components.
- Motor Mounts – the motor mounts are bespoke L-Brackets, for the left- and right- side of the chassis base plate, tailored to the motors used in the robot..
- Geared Motor and Wheel Set – this project used a set obtained commercially.
- Motor Driver Module– provides a Dual H-Bridge (Model L298N) that controls current flow and direction to the motor, with GPIO compatible inputs and a separate power supply input for the motors.
- AA Batteries and holders – for the motor power supply; there are options here as well.
- RaspberryPi Zero WH with GPIO Header– wireless interface and robot controller.
- USB Battery – compatible power supply for the RaspberryPi.
- Misc. Hardware – brackets, mounting posts, screws, nuts, zip ties.
