Robotic arm and robot

The utility model discloses a robotic arm and robot, robotic arm include two arm components that connect through the pivot rotation and wind pivot and one of them arm components fixed connection's wire drawing, the pivot is on a parallel with arm components's length direction. The utility model discloses a robotic arm can rotate for another arm components through the feasible arm components who is connected with the wire drawing of pulling wire drawing, under the conditions, the drive arrangement of pulling wire drawing may not be limited to the rotation junction of setting at two arm components, but set up outside robotic arm, thereby alleviate robotic arm's dead weight, simplify robotic arm's structure, and simultaneously, under the tensile force of wire drawing, arm components can rotate around another one arm components, thereby realize rotation?control. The robot includes foretell robotic arm. 本实用新型公开了种机械手臂及机器人，机械手臂包括通过转轴转动连接的两个手臂构件及绕所述转轴与至少其中个手臂构件固定连接的拉丝，所述转轴平行于所述手臂构件的长度方向。本实用新型的机械手臂可以通过拉动拉丝使得与拉丝连接的手臂构件
