Let's Make Robots!


Trouble with servos!

I’m working on a robot that’s supposed to place dominoes in a track. As part of the design, there’s an arm that grabs and places the dominoes.

Picaxe resetting or stuck in fatal loop


I'm reprogramming Robot Leader, and I'd like to be able to use PWM to pulse his LED eyes. The only problem is, I also have to command a servo to turn his head, and the Picaxe28x1 does not allow you to use PWM while you are using the servo command. They both rely on the same timer.

Suicidal Picaxe Program

Here's what happens on a Picaxe 28x1 in a project board when you connect pin C.7 to the Reset pin. Check out areas F and H in this photo.

The reset function in a Pic(axe) is made so that when it is pulled low, the chip resets. An on-board 4700 Ω resistor keeps the pin high during normal operation. The little button pulls it down.

This Picaxe really is stuck in a moment and refuses to believe:

what is wrong?! ..and what can i do!?

okay..         so i just finished my new robot(8 servo quadropod)and started makeing a test program.   when the test program was done i downloaded it to the picaxe and it worked! then i started to try out use the srf05 to see if it was plugged in the right way! so i made another program and tryed it and that worked too!
