Thanks Bullit,

How can i add sensors to the TTL or RS485 line ?

Any idea when the new board is expected?

CM2 based humanoid questions

2008-10-28T12:11:20+01:00

Welcome to the RoboSavvy forums.
I'll try to answer your questions as best I can.
#1 The connectors should be wired in parallel
#2 The CM2+ schematic is here
The CM2+ supports both TTL (on J4) and RS485. Unfortunately the CM2+ does not bring out the AtoD lines from the ATMega128 so you'll either have to modify the board or add sensors on the TTL or rs485 bus. I also know that Robotis is soon to release a new controller that once again brings out AtoD channels. (The CM2 - the older model, brought out the A2D channels but had no TTL interface)

CM2 based humanoid questions

2008-10-28T06:45:26+01:00

Hi,

I have recently started building a Dynamixel based humanoid (Rx28 & Rx64 based).

I had few newbie questions ?

1. I wanted to make a little daughter board to sub divide the serial bus, so i thought i would solder 4-5 Male 4p molex connectors on a pcb. question is how do i interconnect the ports ? direct parallel( all same pins connected ) ?

2. How do i connect some sensors to CM2+ ( analog or digital )? i found few sensor boards for the CM5 but nothing for the CM2. ( since the CM2 is RS485 based and the CM5 is TTL ). Also is there some way of converting from RS485(4p) to TTL(3p) and back ? Can i somehow connect a AX12 to the CM2+ for the head ?

BTW , I have been reading through the forum for the past few weeks and you guys rock! especially for newbie s like me

Thanks
