Abstract

The invention relates to an under-actuated continuum mechanical arm which comprises three driving motors, three driving ropes and a plurality of joints connected in sequence. Each joint comprises a movable platform and a static platform; the movable platform in each joint is connected with three driven ropes; each joint is connected with three variable-diameter driving mechanisms, the driven ropes in each joint are in one-to-one correspondence with the variable-diameter driving mechanisms, and each driven rope in each joint is connected with the output end of the corresponding variable-diameter driving mechanism; the variable-diameter driving mechanism comprises a variable-diameter pulley, and the variable-diameter pulley comprises a variable-diameter outer ring body; and the outer ring body of the variable-diameter pulley in the variable-diameter driving mechanism at each joint is driven by a corresponding driving rope to rotate. The mechanical arm is simple in structure and small in overall weight and size, and meanwhile the flexibility and the load capacity of the mechanical arm can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to an underactuated continuum mechanical arm. Background technique [0002] The continuum manipulator shows a long and thin shape as a whole, and is composed of multiple subsections connected in series. The components of each subsection often have greater flexibility, which makes the continuum manipulator have good compliance characteristics and flexibility. In view of the continuum manipulator Due to the above characteristics of the manipulator, the continuum manipulator is widely used in various fields. [0003] The Chinese patent with the publication number of patent application CN108237524A discloses a continuous robot driven by a line. The robot includes a drive system and a mechanical arm. Mechanism and drive line, the linear drive mechanism is set on the support base, one end of the drive line is connected to the linear drive mechanism, the other end passes through t...
