Alternative Methods for Controlling ROSbot

[srlessard]

Hello,

I would like to use an external USB keyboard instead of the WebUI to control the wheels of the robot. Does the Husarion team provide any support for external controls? Currently, an lsusb command confirms that the ROSbot detects the keyboard, but I do not know if there’s a specific launch file/ROS node you recommend I use.

Thanks,
Steve

Hello Steve,

I think that teleop_twist_keyboard will solve your problem.

Hi Łukasz,

I have been attempting to use this ROS node, and the node appears to run fine, however, I still run into a bridging error described in this thread:

Bridging ROS with CORE2 Module (Unable to sync with device)

Hello, When I go to perform the bridging step discussed in https://husarion.com/tutorials/ros-tutorials/3-simple-kinematics-for-mobile-robot/#3-simple-kinematics-for-mobile-robot-converting-motion-command-to-motor-drive-signal I receive an error message that states: Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino I’ve read the response from this thread: https://community-mirror.husarion.com/t/problem-with-bridgi…

Do you have any tests or potential solutions I can perform to either solve the bridging error or to learn more about the underlying issue?

Thank you,
Steve
