Hi, I just downloaded packages and tried to follow tutorial but I got error message

How can I fix it?

Hi :)

You can change baudrate number in launch file. Please check baudrate supported by your dynamixel in wiki

Thanks Darby

Hi Darby,

It seems like I am having trouble with LN-101, because it works with my USB2Dynamixel Do I need to make some changes to for LN-101?

routiful commented 6 years ago

Have you succeed to connect Dynamixel to Dynamixel-workbench by using USB2Dynamixel? Would you explain me how to connect LN-101 to Dynamixel?

hoon0629 commented 6 years ago

I used CM-700 controller to connect. Yes, it worked with USB2Dynamixel through TTL connection, but LN-101 connection does not work..

routiful commented 6 years ago

If you want to use CM-700 with LN-101, you need to firmware to pass packet for controlling Dynamixel.

OpenCR has example code
