Multipurpose Plywood Robot Prototyping Base

Why to spend your bucks on ready-made metal or acrylic robot bases when you can make one yourself! Yeah, so this video is gonna teach you how to make a plywood robot prototyping base platform. You surely need them when you are a beginner and want to get started with robotics or even when you are planning to prototype a bigger robot project first on a small scale. There is no way to make a cardboard base which will surely fall apart within a couple of projects or to buy acrylic bases which would be beyond your budget. So here is a cheap ye effective solution- Plywood. This can easily be worked upon, durable and will easily fit in your budget without any doubt. You just have to give some time for a little bit of drilling, sanding and cutting.
The video covers the entire process of preparing your plywood base, adding motors and wheels and even to make a DIY motor driver. At last, there is a basic project to check whether if everything is done correctly. In all, you will require a maximum of 3 hours to do the entire process. So this can also be a beginner project for taking the first step to getting started with robotics.
For testing the base with a simple arduino project, check out the part 2 of this video:
The following parts and tools will be required:
