Problems solved by technology

[0002] With the continuous expansion of self-service and intelligent transportation needs in enterprises, hospitals, libraries, etc., people's requirements for the autonomy and flexibility of transport vehicles are gradually increasing, and the existing transport robots cannot meet the increasingly complex needs.
At present, the transport vehicles on the market generally adopt differential steering mechanism, the movement of the vehicle body is not flexible enough, and a large turning radius is required when turning
When the driving space is narrow or crowded, it cannot meet the requirements of use
The control method is also relatively simple, mainly using the magnetic navigation method, the cost is high, the driving route is fixed and difficult to adjust, and cannot adapt to different workplaces

Abstract

The invention discloses an omni-directional mobile transportation robot. The omni-directional mobile transportation robot comprises a shear type lifting mechanism and a car body, wherein the shear type lifting mechanism is fixed on the car body and comprises a transportation table, a screw sliding table, a stepping motor and a shear type support, and the stepping motor drives the screw sliding table to move and then controls the transportation table to lift and drop; the car body comprises a frame, a walking mechanism and a lower panel; the walking mechanism comprises Mecanum wheels, wheel motors, suspensions and motor mounting plates; a storage battery, a control panel, a brushless DC motor drivers, a Bluetooth expansion board, a voice sensor, an obstacle avoidance sensor and a stepping motor driver are fixed on the lower panel; tracking sensors are arranged on the walking mechanism. The transportation robot can realize omni-directional movement, transports objects flexibly, has a transportation table lifting function and can select and switch a control mode according to different working environments and transportation requirements, and therefore, adaptability and working efficiency of the transportation robot can be improved.

Description

technical field [0001] The invention relates to an omnidirectional mobile transportation robot. Background technique [0002] With the continuous expansion of self-service and intelligent transportation needs in enterprises, hospitals, libraries and other occasions, people's requirements for the autonomy and flexibility of transport vehicles are also gradually increasing. Existing transport robots cannot meet the increasingly complex needs of use. At present, transport vehicles on the market generally adopt differential steering mechanism, the movement of the vehicle body is not flexible enough, and a large turning radius is required when turning. When the driving space is narrow or crowded, it cannot meet the requirements for use. The control method is also relatively simple, mainly adopting the method of magnetic navigation, which has high cost, and the driving route is fixed and difficult to adjust, so it cannot adapt to different workplaces. Due to the different height...
