What does a small fish robot do?

Before retirement, cervical spondylosis was caused by long-term work. With the increase of age, the pain in neck and shoulder tends to increase, the arm can't be lifted, the back can't be rotated, and dizziness and insomnia appear. In order to relieve the pain, acupuncture and massage failed. Occasionally experience that the smaller the Harbin Institute of Technology, the better the robot. Now my arms can be lifted, my hair can be combed, and my sleep is obviously improved.
