4. General Notes

  • When conducting experiments with the A1 that may impact its stability, the emergency stop and leash provided should be used where necessary.

  • The A1 should be powered off and its battery should be replaced whenever there is only 1/4 of the battery LED indicators left lit and blinking. This indicates that the battery level is low (0-25%).

  • Before powering off the A1, be sure to bring it down to the damped proning state first to prevent the robot from dropping down from a height. To do so, get the A1 to the “proning state” with “L2+A” and finally press “L2+B”.
