Here is a simple but neat EV3 robot vehicle that can be a base for more complicated builds. CAST3R BOT moves around with… a castor! Yes! Two tires are connected to the large motors. Two turn, it just applies more power to the other wheel. The castor, like a shopping cart, moves with the flow. I’ve added an InfraRed Sensor to the back so I could Remote-Control it. A more complicated build based on CAST3R BOT will be uploaded by me tomorrow.
