An electric lifting chassis for a field operation robot

Abstract

The invention discloses an electric lifting chassis for a field operation robot. The electric lifting chassis for the field operation robot comprises a main rack, a power source, a controller, walking mechanisms, steering mechanisms and lifting mechanisms, wherein the power source, the controller, the walking mechanisms, the steering mechanisms and the elevator mechanisms are installed on the main rack, the controller is connected with the power source, the walking mechanisms, the steering mechanisms and the elevator mechanisms respectively, the walking mechanisms, the steering mechanisms and the elevator mechanisms are connected with the power source respectively, the walking mechanisms comprise a plurality of wheels and driving torque motors, an inner rotor of each driving torque motor is connected with a wheel axle of each wheel, the controller is connected with the driving torque motors, the controller converses an output rotation speed of each driving torque motor according to a set vehicle speed and controls the rotation of the inner rotor of each driving torque motor to drive the wheels to rotate, a first encoder is arranged in each driving torque motor, the first encoder is connected with the controller, and the controller adjusts the rotation speed of the inner rotor of each driving torque motor according to the speed signals fed back by the first encoder to achieve accurate walking.

Description

Technical field [0001] The invention relates to an electric lifting chassis, in particular to an electric lifting chassis with adjustable wheel pitch used for four-wheel independent driving and steering of a field operation robot. Background technique [0002] At present, the technology of small field robots has become a research hotspot at home and abroad. As the main body of field data collection and data processing, the robot chassis is mainly used to carry multiple sensors to realize the robot's navigation and path planning, and complete specific field tasks. However, due to the complex working conditions in the field, there are extremely high requirements on the driving ability and steering ability of the robot chassis. When working on different crops, the chassis needs to be automatically adjusted according to the crop height, and the crop planting standards in my country are different, resulting in changes in crop row spacing. Larger, it also requires the robot to automatic...

Problems solved by technology

However, due to the complex working conditions in the field, there are extremely high requirements for the driving ability and steering ability of the robot chassis. When working on different crops, it is necessary to automatically adjust the chassis according to the height of the crops. Moreover, the crop planting standards in my country are different, resulting in changes in the row spacing of crops. Larger, also requires the robot to automatically adjust the different line spacing

In the current electric chassis at home and abroad, there is no technology for electric lifting chassis with adjustable wheelbase for four-wheel independent drive and steering.
