What affects patrol accuracy?
Here are some tips to improve patrol accuracy.
- i) Scout’s Mecanum wheels are optimized for hard floors. It may drift on some soft carpets.
- ii) The initial angle is critical. During patrol path setup and each patrol, the first thing the bot would do is to calibrate. That includes comparing the front view to determine the launch angle. Please make sure that you don’t step in front of the camera during patrol setup and patrol. If both patrol setup and the patrol are in the same lighting condition, e.g. both in night vision, the initial angle is calibrated with better accuracy.
iii) Patrol in open space. The team is still improving the algorithm. For now, each time the bot performs obstacle avoidance, the accuracy drops down. Fewer obstacles, the bot can be more accurate to follow the pre-programmed path.
- iv) Always start with simple patrol loops. End the patrol path setup 3ft in front of the charger so that the bot won’t run behind the charger.
- v) Calibrate the IMU sensors from time to time via the App. Setup -> Control -> Calibrate IMU Sensor. During calibration, the bot should be on a leveled surface, so that gravity won’t affect other planes.
