Robot drives at high speed upon loss of WiFi

Open matjazp opened this issue 6 years ago • 4 comments

When the robot looses wifi the robot apparently drives off at high speed for unexplained reasons. This occurred during a hackathon with multiple users logging in to the robot at the same time.

Can you provide more details on exactly what programs you tried?

Are you using move_basic, or cmd_vel only? What else is running?

  • Issue occurred when running either fiducial follow or Teleop
  • Robot operating in AP mode
  • Loss of Wifi induced by moving the robot away from laptop
  • Only seemed to be on certain (perhaps a single example) RPI
