Problems solved by technology

However, since the encoder is directly arranged on the driving wheel or the driving motor, once obstacles block or the ground is wet and slippery, the driving wheel will slip, resulting in inaccurate moving distance of the robot converted by the encoder

Abstract

The invention discloses a displacement detection wheel, a robot chassis and a movable robot. The displacement detection wheel comprises a fixed support, an axle and a displacement wheel rotationally installed on the axle. The end face of the axle is in rigid connection with a magnetoelectric encoder. The displacement wheel is in rigid connection with a strong magnet arranged face to face with themagnetoelectric encoder at an interval. The axle is connected with the fixed support through a Hawken linear mechanism. A torsional spring used for pushing the displacement wheel to be tightly attached to the ground is connected between the Hawken linear mechanism and the fixed support. According to the displacement detection wheel, the displacement wheel is free of transverse displacement duringupward movement through the Hawken linear mechanism, and the displacement detection wheel can be installed conveniently on the premise that an existing regional space is not changed; force is applieddownwards to the displacement wheel through the torsional spring, the displacement wheel is tightly attached to the ground, and then slipping of the displacement wheel can be effectively avoided; andthe strong magnet and the magnetoelectric encoder are installed on the displacement wheel and the axle, the displacement of the robot is measured by the magnetoelectric encoder, and the cost is low.

Description

technical field [0001] The invention relates to the field of autonomous mobile robots, in particular to a displacement detection wheel, a robot chassis and a mobile robot. Background technique [0002] A mobile robot is a comprehensive system integrating environmental perception, dynamic decision-making and planning, behavior control and execution.
