How to create a great map?

Tip 1: Select a feature-rich area as the start point

A good start point need to has rich features, such as corners, pillars, left and right passages, inclined walls, etc.,

Note: please make sure Nimbo always can see the 90° corners within 15 meters

Tip 2: Recording map at a low speed

It is recommended to use a speed of 0.6m/s to record the map. It will help the robot to scan the feature points of the current environment

Tip 3. Avoid turning at the beginning

Each turning process will build up errors (tire spinning on the ground) during recording the map. We recommend going a straight line at the beginning of map recording, and avoid sharp turning at the first few minutes.

Tip 4. Turn 360° before turning the corner

When the Nimbo need to turn a corner, make Nimbo turn 360° first.

Tip 5. Make more overlap when close the loop

When back to the start point but the loop cannot be closed, continue walking along the previous map for a while more than 10 seconds, more than 2 meters

Tip 6. Finish a small closed loop first

The robot should finish a small loop first. After the small loop is completed, the map is gradually extended to the periphery for map construction.

Avoid making areas with similar features such as long straight hallway as closed-loop points.

Tip 7. Avoid recording map that are unrelated to the current loop

Nimbo will cumulate errors during the process. And it is easy to cause the loop to be too different between the start point and the end point, which will result in failure.

Tip 8. Avoid turing around and walk back and forth before the closing the loop

Try to take Nimbo walk straight instead of turning around and walking back and forth, which will cause the failure of closing loop and make the map being blurry

Tip 9. Try top recording the map next to the wall

One side of the Nimbo is a open area, please make Nimbo close to the wall on the other side to finish the map.

Tip 10. Recoding map in a large area

In a large area, such as shopping malls, there are many transparent glasses and the environmental characteristics are not obvious. If there is a position with more features in front of the robot, such as pillars, left and right passages, inclined walls, etc., you can stop at the appropriate position, then make a 360° turn close to the feature-rich position, and wait for the area clearly shows on the app. Please do not make Nimbo go back during the rotation.
