AI Technical Summary
Existing pea planters cannot completely free up manpower, cannot achieve reasonable control of planting density, and cannot plan paths and avoid obstacles according to the geographical environment of farmland.
A wheel-legged spherical seed planter was designed. It uses a servo motor, large gear, small gear and roller mechanism to achieve autonomous walking. It combines ultrasonic ranging and infrared sensors for path planning and is equipped with seed picking and sowing mechanisms to achieve quantitative sowing and obstacle avoidance.
It has achieved autonomous walking, reasonable planting density and path planning, and can avoid obstacles, thus improving sowing efficiency.
