I have a problem when I try to control my robot using keyboard. The robot first takes so much time to response then when it responds, it lags and sometimes drives forward when I ask backward , sometimes it drives when I did not send any signal to drive even though the internet connection is fine, battery was above 10V and i did not encounter this issue before i happened this week. what could be the issue? also, this issue happened indoor and when I tried to do it outdoor it became worse.
Hi @jaj,
Thanks for the detailed description. As a first step, we recommend trying gamepad teleop (remote controller), as it is typically more responsive and can help determine whether the issue is specific to keyboard input.
The behavior you’re seeing (delay, lag, and unexpected motion) is often related to command latency, multiple command sources, system load, or power conditions. We’d like to gather a bit more information to help narrow this down.
Could you please share:
- The robot serial number
- The exact battery voltage reading (since behavior can vary significantly depending on voltage)
- Whether there are any other robots or ROS 2 systems on the same network
- If you are running any additional nodes besides the keyboard teleop and driver
- CPU usage while reproducing the issue (you can run
topand share a screenshot or output)
Additionally, could you try running the robot in SUPPLY mode and repeat the teleop test? Please let us know if the behavior improves.
Also, please let us know how you are connecting to the robot (SSH, remote desktop, etc.).
Looking forward to your response so we can continue troubleshooting with you.
Best,
Jason
