Comments

hi @raess1 . thank you |
This Doisyg node you posted also fails to work. It has trouble reading data. |
HI,
I am trying out the roboclaw with ros and i have sucessfully made it work with teleop_twist_keyboard and joy_teleop. The problem is that the Roboclaw_node dies after a while when i have the button "pressed in" or the joystick pressed in.
I get the following error:
process[rosout-1]: started with pid [14545]
started core service [/rosout]
process[roboclaw_node-2]: started with pid [14562]
process[diagnostic_aggregator-3]: started with pid [14563]
Traceback (most recent call last):
