One leg shifting off-center on powerup

Postby TheGreatAndPowerful » Wed Oct 25, 2017 10:02 pm

I actually have a few problems at the moment:

1) When I turn on the mePed, the front left leg, immediately moves from the 90 degree position back about 15 degrees. As I have it walk forward, it continues to move further and further back until it gets bound up with the left rear leg. I don't really know how to approach diagnosing the error to even tell if it is hardware or software. I suppose I could switch that leg with another to see if the problem stays with the leg. My initial assumption is that the servo motor doesn't know where it's center position is located.

2) I find that even if I direct it so go back, left or right, it only wants to move forward. I can get it to dance (8) and wave(2) and when I choose a new command, it repeats the last command at least once but even trying to go back, if it was going forward, it just continues to do so.

3) Are the eyes (ultrasonic sensors) active? I thought that the would keep the mePed from running into a wall or other object but it does not. I have been going throught the code from the website trying to learn and to see if that is functional or not.

4) You had mentioned, and I see the connector, that there is an option for a bluetooth receiver on your custom board. I was wondering if you recommended a sensor for that position. I work with some iOS and Android developers and they could help me right an app to use that I believe.

Thanks for your help
