This is a sturdy little robot that I made a while ago that can get over anything. Well, not exactly, but it can get over dictionaries! It has 4 treads that can pivot freely, enabling it to have great traction when driving over books etc. Here’s the movie:

Here it is… my latest creation worth publishing! It’s a sumo bot that was for the NXTLOG sumo challenge that as usual I missed due to the deadline being a couple months before I made this. Oh well, at least I can still post it here! So, pretty much what’s cool about it is traction. It has 6 wheels that give it awesome traction. The only disadvantage is that it drives kind of slowly, but if it collides with the opponent boy are they going down! The program isn’t really worth posting because it just has the robot stay on the table. There is no ultrasonic sensor to seek the opponent because due to limited space in my LEGO room (AKA bedroom) It would detect my dresser and attack it

Hello, I’m NXTMonger, and I would hate to have a post just telling you who I am so here’s one of my projects: It’s called PPS – Ping Pong Shooter. It has a magazine of about seven ping pong balls and can shoot them out quite fast. In the video it’s remote controlled by me.
