Some Good news, Some Bad...

Well, I haven’t updated in a while, so I figure I will fill y’all in…

Today I received a letter from a school district in California telling me that I have officially passed the NASA Ames robotics course I took this summer. That was some good news! I have finished the control system for my robot, but was having some problems with it, so I broke it down and am working from the ground up, trying to find what is wrong. Unfortunately I do not have an oscilloscope to read the waveforms. I am going to try to get that working, and then I’ll be in good shape!

Too bad you don't live by me or you could borrow my FLUKE network tester. It does square waves and sine waves. Comes in pretty handy at work too :p

I'm absolutly sure that it's a hardware problem, I swaped the servos out twice to see if it was either the servos, or whether the HSERVO command wasn't running on those IO pins. And then I tried just wireing up the servos to see if they still move, and they didn't. According to thier specs they should be able to power the legs, but I used alot of aluminum so it might be too heavy for them. The knee and ankle servos work fine, but as you go up the leg those servos burn out. So i'm thinking of maybe using balsa wood being it's verry light and pretty stong. But thanks for your help.
