Abstract

The invention discloses a mechanical arm with variable degrees of freedom and a telescopic robot. The mechanical arm with the variable degree of freedom comprises a knuckle arm, a joint mechanism and a telescopic mechanism. The knuckle arms are cylindrical, the knuckle arms are arranged in sequence, and the sizes of the knuckle arms are reduced in sequence, so that any two adjacent knuckle arms stretch out and draw back; a joint mechanism is arranged between any two adjacent knuckle arms, the upper end of the joint mechanism is fixed to the lower end of the knuckle arm with the small size, and the lower end of the joint mechanism is connected to the interior of the knuckle arm with the large size in a sliding mode, so that when the knuckle arm with the large size is exposed out of the upper end of the joint mechanism, the joint mechanism is driven, and the knuckle arm with the large size is driven to rotate. The upper end of the joint mechanism swings relative to the lower end of the joint mechanism so as to change the angle between the two adjacent knuckle arms; the lower end of each joint mechanism is connected with a telescopic mechanism, and the telescopic mechanisms are fixed in the knuckle arms, so that the lower ends of the joint mechanisms are pushed to slide in the knuckle arms through telescopic driving of the telescopic mechanisms. The technical problem that a multi-degree-of-freedom robot occupies a large space in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of robotic arms, and in particular, to a robotic arm and a telescopic robot with variable degrees of freedom. Background technique [0002] The application of grasping robots has penetrated in various industries. For robots, they all have a certain number of degrees of freedom, and then determine an accessible space for grasping. For this type of robot, its relative size is convenient. Fixed, to achieve farther grasping only to change the structure of the entire robot to achieve. [0003] At present, most of the cables of assembled robots are placed outside, so it is necessary to design corresponding devices to protect or beautify the cables, so that the appearance can be more suitable for people's aesthetics. The use of the robot should occupy a certain range of space. When not in use, it is either placed in place, or it needs to be moved to a suitable position for placement. Therefore, a robot ...
