Today I went to a FRC. It was fun, and I joined a team only 3 weeks earlier, and hopefully things will turn out good. So far they want me to be their lead programmer, and it sounds like fun. Today’s match was a ton of fun and it is a great place to meet people that love robotics. I think these robots are more fun than your typical robotics, and it beats the FLL by 100 times better. These robots make your Lego NXT sets look like toys [well, lego's are toys aren't they?]
They seem to have a lot of fun and it included having the best food I’ve had at a robotics event – a group was fundraising for their robotics team and was selling these great burgers that were amazing [partially because they were cooked on a propane stove] and it was just a fun experience.
On the bad side, I found out that port A on my newer NXT no longer works – the motor output is fried. The rotation sensor seems to work OK though… Probaly something I should report to Lego.
I could probably take it apart and find the problem, but there’s no point. I’m probably better off making it into a full rotation port and build a rotation sensor so that I can do it without a huge motor. I looked up the specs, and it’s a simple trigger system
1 degree equals this en-emulated into the two signal wires:
And opposite order for the other direction.
I tried making one with light resistors, but I can’t get it to work. Probably better off using them as light sensors. I feel that light sensors reflecting off an object is more accurate at telling distance than the Ultrasonic, which works best in port 4 than any other [partially by the raised transfer speed/communication]
I’m thinking I’ll work some more on the printer.. make a skid steer out of the other robot for now, at least it only takes 2 motors, and I could use the prototype board to make a third motor port…
There were a lot of cool ideas at the FRC and am considering what to build out of the ideas I saw there,n I could really improve my robot with their ideas.
