MECHANICAL ARM AND SELF-GUIDING OPERATION METHOD FOR MECHANICAL ARM

WIPO Patent Application WO/2019/095506

A1

A mechanical arm and an operation method, said mechanical arm comprising a base (10), a plurality of joint arms, a ranging device (30) and a control device; the plurality of joint arms comprises a first joint arm (11) and a second joint arm (12), the plurality of joint arms being connected to each other in an end-to-end manner and provided in a same vertical plane; the ranging device (30) is provided at the end of the second joint arm (12), and the control device is configured to acquire, when the ranging device (30) locates an operation target of an operation portion (40), a first distance between the ranging device (30) and the operation position of the operation target (50) and an included angle between the first joint arm (11) and the second joint arm (12), calculate coordinates of the operation target (50) with respect to the base (10), and calculate a rotation angle of each of the plurality of joint arms according to the coordinates, thereby controlling rotation of each joint arm. The invention converts the inverse solution operation of a three-dimensional space of the mechanical arm into the operation of a two-dimensional space, simplifying the calculation process, reducing the operation amount, and improving the system processing performance.
