The motors and the wheels are an essential element of the robot, so we as a team decided to use rounded wheels which will make our robot move smoothly and without much drag. The wheels that we picked were thin to fit within size restrictions. We looked at some websites to buy our robot’s pieces of equipment from, such as http://www.aliexpress.com, http://www.amazon.co.uk, and http://www.ebay.ie.
My team started soldering the motors so that we can use it in our circuit next week, while I was working on programming and coding for our robot with my lecturer.
