Lego nxt robot fighting

We do have experience coding. Was it because we the adults work at Lego? A clear goal, a bit of research, and lots of integration testing! First we set a goal. Nevertheless, I convinced them to start in small steps. We knew nothing about these kind of competitions so we started by looking at some youtube clips to see what kind of designs and strategies people were using. That gave us some ideas. We had our candidate!

Time to train him up. The original SmartBot was gradually stripped of sensors and stuff and became DummyBot — our training dummy. Not just once, but repeatedly. So we went through a bunch of cycles of integration testing and tweaking the hardware and software. We kept failing over and over often in funny ways , but every iteration we got a bit closer to winning. One interesting thing happened along the way. We noticed on the youtube clips that many robots tried to lift and topple their enemies.

So Dave built a pretty elaborate construction for that, and I helped write the code to control the lifter. In theory it was awesome, in practice it was useless. We wanted to keep Robit simple and focused on one thing — putting up a proper fight!

We figured that would help us get under the wheels and push or topple the opponent. Nothing unique, most robots have something like that in the front. However it was hard to get the right angle of attack.

So the software needed some work. A robot should also avoid leaving the arena, usually by means of a sensor that detects the edge. The most common "weapon" used in a sumobot competition is an angled blade at the front of the robot, usually tilted at about a degree angle towards the back of the robot. This blade has an adjustable height for different tactics. Robot-sumo is divided into classes, fought on progressively smaller arenas [2]:.

The robots usually have to fit in a one-foot cube. Classes are further divided into remote-controlled and autonomous robots.

Also, there might be a tethered category varies. Sumo robots are built from scratch, from kits or from Lego components, particularly the Lego Mindstorms sets.

Some sumo bots are built with only wood and motors for more of a challenge. The usual size for the wood is 12" by 12". It makes it hard to construct a really large robot with this piece of wood. From Wikipedia, the free encyclopedia.
