Assembly and robot having the same

An assembly for a robot, comprising:

• a shoulder;
• an arm rotatably connected to the shoulder;
• an armor decorative member connected to the arm and located adjacent to the shoulder;
• a connection assembly located between and rotatably connected to the arm and the armor decorative member, wherein relative rotation between the arm and the connection assembly and between the armor decorative member and the connection assembly enables the arm to continue to rotate after an upper end of the armor decorative member comes into contact with the shoulder;
• and
• a connection shaft;
• wherein the connection assembly comprises a first connection member, a second connection member, a first torsion spring and a second torsion spring, the first connection member comprises a first end rotatably connected to the armor decorative member and a second, opposite end, the second connection member comprises a first bar and a second bar, the second end of the first connection member is rotatably connected to the first bar, the first torsion spring is connected to the first connection member and configured to apply a restoring force to the armor decorative member, and the second torsion spring is connected to the first bar and the second bar and configured to return the first connection member and the second connection member to original orientation thereof with respect to the arm;
• wherein the first end of the first connection member defines a first connection hole, and the armor decorative member defines a mounting hole, one end of the connection shaft is fixed in one of the first connection hole and the mounting hole, and an opposite end of the connection shaft is rotatable in the other one of the first connection hole and the mounting hole, thereby rotatably connecting the armor decorative member to the first connection member.
