Does anyone have experience working with Dynamixel ax12a motors? I’m having trouble using their arduino libraries. The only function I’ve been able to get working is the ax12a.setEndless. I read that the signal that they require is half duplex, so I’ve tried using a variety of chips/transceivers (thvd1452, thvd1410, and SN74LS241N) to no avail. Has anyone else had this problem? Are there good alternatives to the ax12a in terms of size and power output?
