This ROS package defines several nodes and message types for working with the Brunel Hand by Open Bionics. It is documented on the ROS Wiki at https://wiki.ros.org/brunel_hand_ros
hand_dev_file: device file corresponding to serial connection with Brunel Hand. Default value is /dev/ttyACM0
/fpose /motion_primitive /raw_input
Installation and dependencies
This package is being developed with the ROS Kinetic distribution as its initial target, but backward and forward ports are planned.
- serial (on GitHub: https://github.com/wjwwood/serial/)
As an initial demonstration, try
roslaunch brunel_hand_ros toggle_fist.launch
This will start examples/toggle-fist.py and the main interface node, named
proxy. The hand should begin to alternate between open and closed fists.
Internal interface notes
For interaction with the hand firmware directly over USB, the serial connection speed is 115200 bps (bits per second), and no carrier-watch. E.g., using C-Kermit and supposing that your host computer associated /dev/ttyACM0 with the USB device,
kermit -l /dev/ttyACM0 > set speed 115200 > set carrier-watch off > set terminal lf-display CRLF > connect
After connecting, try
# to get the system diagnostics, and try
? to get the
list of serial commands.
