TR3ADBOT is a small and simple mobile tank. It can conquer obstacles. I also have a bunch of sensor attachments you can add to TR3ADBOT, but I don’t want to publicize it right now. Why? (Hint: I’m drafting a new EV3 book right now, and this is gonna be one of the robots included. If I show you all features now, why write book? Please understand, and don’t let this upset you!) Enjoy!
