ROTH walked autonomously for the first time this weekend thanks to his new 4000 mAh LIPO battery! Unfortunately a short time later one of his servos overheated and took out the servo controller shield (culminating with the white puff of death). Ironically the overheating had nothing to do with the battery and occurred while ROTH was plugged into the wall. This isn't the first time that overheating servo issues have been observed, but this is the first time that they've caused any problems. The most likely cause is a design issue that requires the hip servo to be nearly constantly engaged. As a result the hips have to be redesigned.
Also, there have been a few requests for the parts manifest for ROTH. Keep in mind that this is still subject to change, but here is the most current draft. Let me know if anyone has any questions.
