I am making a robot base for a part of Shift it! Warehouse Automation Design Challenge. Building hardware is hard and more than hard for building robots where you have to work with lots of motors and sensors. When you have several medium or high-power motors in your project, providing the required amount of power also appears as a real challenge. Even sometimes you will get unstable behavior from your robot for not choosing the right size/type of wire. Making a bot from scratch involves lots of soldering and wiring works. Choosing a ready-made chassis can help to save a plenty amount of time. As the total project contains many tasks and the deadline is approaching soon, I selected a DFRobot Rover 5 tank chassis for the robot base to reduce some unnecessary complexity. I attached an acrylic sheet on top of the chassis by using zip ties.
I used a Dual DC Motor Drive Module 7A 160W, 24V for driving the motors. Using some M3 screws and nuts I attached the motor driver board and Arduino board on top of the acrylic base as shown in the image below.
I used a 3-cell li-po battery for powering the motor driver board.
