Robot precision

[wol aye]

Dear All,

Please kindly help to throw more light on the issue below:

Since every robot has different behaviour to different conditions based on loading effect, power draw, weight, dimensions, drag, delays in controller, e.g. An extra weight on an already built 2WD AMR robot could change its precision, except someone would need to re-calibrate the robot. How then have they been able to build an autonomous robot like Amazon Zoox that works precisely even with 1 or more passengers on board without affecting its performance?

Regards,

Wol
