AI Technical Summary

⚠Technical Problem

The steering mechanism of traditional lawnmowers is prone to wear and tear, leading to a decrease in accuracy. Furthermore, non-contact solutions are not strong enough to resist interference or are affected by instability in complex outdoor environments.

⚗Method used

An angle sensing device employs transmitting and receiving electrodes coupled by capacitive coupling. This utilizes the principle of capacitive coupling for signal transmission, avoiding mechanical wear. The absolute angle of the steering device is determined by the circumferential distribution of the electrodes and the change in the coupled signal.

🎯Benefits of technology

It improves the precision and response efficiency of steering control, simplifies the steering system structure, reduces assembly difficulty and cost, and enhances adaptability and stability in complex outdoor environments.
