The robot includes a body, the body has a working face thereon, a mechanical arm is provided on the working face, the mechanical arm is fixedly connected with a guiding means at one end away from the 10 body, the mechanical arm has a first joint component and a second joint component, the first joint component is connected to the working face, the second joint component includes a second joint seat, a second joint shaft, and a second joint arm, an encoder and a clutch are provided on the second joint seat, the clutch controls the second joint shaft to rotate, the second joint shaft is sleeved with a torsion spring thereon assisting 15 the second joint arm to rotate. In this technical solution, with the design of the torsion spring in the secondjoint component, when an operator rotates the secondjoint arm to adjust a spatial posture of the mechanical arm, the torsion spring can enable a doctor's operation to be more labor-saving, thus reducing a load of the doctor in an operation process.
