Make your Duckiebot Move Tips: Be VERY patient
- close the Portainer Interface (containers) when it's not moving again or refresh the page;
- reconnect with the docker token: https://docs.duckietown.org/DT19/opmanual_duckiebot/out/dt_account.html
- Keep entering $ ping yourrobotname.local until it prints time in the terminal;
- Turn off the demo and turn it back on in the contanier; run the demo code in the terminal;
- Keep pressing/testing/waiting until the command is processed. Be patient and the robot will move eventually!
