Zero-ing Our Robonova-1

Has anyone else encountered any problems while trying to set the zero positions for the servos on the Robonova? When my collegues and I attempted to do this, we were flabbergasted when a knee servo started ssssmmookkin’. Furthermore, our servo controller seems to be out of commission; moreover, we checked if power was being supplied to the board and it is. The LED turns on, though we suspect that it’s wired directly to the power slot. The knee servo that started ssssssssmmmookin’ does not longer work and without a functioning servo controller, we are stumped. We might have inflicted some damage on the board indirectly by charging the battery irregularly (off and on for like 10min periods and with the board attached) and it may be possible that we had the board turn on while it was charging. Does anyone have any ideas on how to solve this problem? We called Hitec, they told us that we need to send the defective board to their Customer Service Center.

Wow! I don’t think charging the battery could ever be the cause of a servo ssssssssmmmookin’ 8)

I have found Hitec are good at replacing damaged controllers and servos.

You might have made errors in the construction, so some servos are stalled, they will get hot and burn out. If you have the charger connected then you applying over 7Volts supply, when the spec is 6V, so they go even quicker.

If are not confident with your construction, add the servos one by one and zero them in turn, feeling the temperature and checking the correct servo moves. Servos may stall if you have the wrong servo disk position, or servos plugged in the wrong place. Zero positions are all usually close to 100.

The controller LED is turned on by software. Are you sure your serial communication to the board is OK, and the board type is set to C3024 ?

thanks for the advice. We are currently working on establishing a connection with Hitec so that we may send the unit back and have them fix it. Does anyone know if this would be free of charge?
