2016-03-29 07:57:03 -0500 asked a question DARwin-OP walk with Gazebo!? Real hardware.

How i can make the real robot walk ? I have tested the simulation with the darwin-op urdf. I want know how interface the dynamixels with the ROS (usb2Dynamixel)

Hi , I'm having some problems with the pyserial. I execute chmod 777 /dev/ttyUSB0, but I get this error:

self.dxl_io = dynamixel_io.DynamixelIO(self.port_name, self.baud_rate) File "/opt/ros/indigo/lib/python2.7/dist-packages/dynamixel_driver/dynamixel_io.py", line 68, in __init__ self.ser.setTimeout(0.015) AttributeError: 'Serial' object has no attribute 'setTimeout'
