Problems solved by technology

At present, it is difficult for wheeled mobile robots to move in all directions in a narrow space. In order to adapt to more complex terrain and narrow spaces, mobile robots must be able to move in all directions and have strong obstacle climbing capabilities. However, due to the harsh environment of earthquake rescue and detection, it is necessary to make better improvements in the size and weight of mobile robots

Abstract

The invention discloses a wheel-tracked mobile robot based on Mecanum wheels. The mobile robot comprises four Mecanum wheels, four track leg mechanisms, a vehicle body, four main driving mechanisms, four track leg swinging mechanisms and the like, is an important part of a ground mobile robot, a has the characteristics of small size, light weight, and long working time, and is often used for earthquake rescue, investigation and detection and the like. The mobile robot has multiple movement modes of wheel type, crawler type and crawler and leg combined type, front and rear crawler legs can swing by 360 degrees, the front and rear crawler legs can also serve as driving systems, and the proper movement modes can be switched according to terrains, so the mobile robot can adapt to more complex terrains and narrower spaces.

Description

technical field [0001] The invention relates to the technical field of mobile robots, in particular to a wheel-track mobile robot based on Mecanum wheels. Background technique [0002] The wheel-track compound mobile robot is an important branch of ground mobile robots, and it has a close relationship with people's life. In daily life, ground mobile robots are mainly used to assist people to walk, climb stairs and other obstacles. They can also help people transport valuables to their destinations lightly. Stair climbing is the most common obstacle. [0003] Now, due to people's higher and higher requirements for mobile robots, the demand for walking and obstacle-surpassing capabilities in unknown environments is also increasing. At present, it is difficult for wheeled mobile robots to move in all directions in a narrow space. In order to adapt to more complex terrain and narrow spaces, mobile robots must be able to move in all directions and have strong obstacle climbing c...
