Robot drives at high speed upon loss of WiFi

[matjazp]

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.

Steps to make it occur

• Run a program any program
• After loss of WiFi
• Stop for 2 minutes
• Robot will drive off at high speed!

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

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

[davecrawley]

• 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
