Assisting robot

Abstract

The invention discloses an assisting robot which comprises a multidirectional motion car body and a clamping device, wherein the multidirectional moving car body is provided with a first motion arm, a second motion arm and a transmission part connecting with the first motion arm and the second motion arm; each of the first motion arm, the second motion arm and the transmission part is provided with at least one multidirectional rolling device; the multidirectional rolling device is provided with a plurality of coaxial rolling units and a plurality of coaxial driving units; each of the rolling units is provided with a circular ring shaped bracket; a plurality of rotating wheels are annularly distributed on the circular ring shaped bracket in the circumferential direction of the circular ring shaped bracket; the rotation axis of the rotating wheel is parallel with the tangential direction of the outer circumference of the circular ring shaped bracket and is perpendicular to the rotation axis of the circular ring shaped bracket; a plurality of circular ring shaped brackets are fixedly connected one by one; the driving units are used for driving the circular ring shaped brackets to rotate; the clamping device is provided with a clamping mechanism and a handheld part; the clamping mechanism is used for clamping an object; and the handheld part is used for receiving applied force inputted by a user. The assisting robot realizes multidirectional flexible motion and turning through an integrated structure.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to an assisting robot. Background technique [0002] With the rapid improvement of modern productivity, the demand for object transportation has shown explosive growth. Existing transportation devices are mostly concentrated in the field of large and medium-sized machinery, such as cranes, booms, etc., which are difficult to be applied in daily life. [0003] There are also some handling devices in daily life, such as trolleys, small shopping trailers, etc., which mostly use the rolling of wheels to carry objects beyond people's own weight. However, limited by the structure of the wheels and the car body, most of the existing hand-held transportation devices only have the ability to move in one direction, the movement reliability is poor, and the flexibility is not good when turning. It requires a large driving force and is very laborious to use. If an external steering control ...

Problems solved by technology

However, limited by the structure of the wheels and the car body, most of the existing handheld transportation devices only have the ability to move in one direction, the movement reliability is poor, and the flexibility when turning is not good, and a large driving force needs to be applied, which is very laborious to use

If an external steering control mechanism is used, the structure of the car body will be bloated and the weight will increase sharply, which will bring additional side effects
