Embodiment Construction
[0025] In order to solve the problem of the travel path deviation of multi-motor-driven mobile equipment caused by individual differences in motors, transmissions and wheels in the prior art, the present invention provides a calibration method and device for multi-motor-driven mobile equipment , by monitoring the motion trajectory of the mobile device, and adjusting the control parameters of the motor of the mobile device according to the motion trajectory of the mobile device, to eliminate the deviation path caused by the individual differences of the motor, transmission and wheels, so that the Mobile devices are capable of traveling in a straight line. The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The invention discloses a calibration method and device of a mobile device driven by multiple motors. Movement track data of the mobile device is collected in real time; when the deviation between the movement track and a preset route is larger than a preset threshold, control parameters of the motors of the mobile device are adjusted according to the preset route, and the mobile device is enabled to move along the calibrated route. According to the invention, the mobile device is calibrated without additional circuit design, so that the production cost is greatly lowered; secondly, the calibration process is aimed at the final moving path of the mobile device, and the problem that the calibration effect cannot reach an expected effect due to errors of wheels after only the motors or a transmission device is calibrated is solved; and finally, the operation is simple, and the calibration device of the mobile device driven by multiple motors can be automatically calibrated, so that the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a calibration method and device for a mobile device driven by multiple motors. Background technique [0002] With the increasing intelligence of electronic devices, more and more electronic mobile devices such as four-wheeled robots, sweeping robots, and even electric vehicles have entered our lives. In order to make the structure modular and reduce the difficulty of design, these devices are often driven by multiple motors. An important problem that follows is that if no control adjustment is added, due to the individual differences between the motors, transmissions and wheels, the When walking in a straight line, it is often impossible to travel in a straight line. For example, due to the fact that the rotational speed of multiple motors is not necessarily strictly the same under the same conditions, or due to the different materials of the gears of the transmission dev...
