An automatic performance apparatus including a body, a clamping mechanism, a bow-waving mechanism, a stopping mechanism, and a control system is provided, which is able to play violin or cello.

An automatic performance apparatus including a body, a clamping mechanism, a bow-waving mechanism, a stopping mechanism, and a control system is provided. The body has an inner space and a top surface. The clamping mechanism is disposed on the top surface of the body, and is adapted to clamp and position the violin. The bow-waving has a installing base and a robotic arm. The installing base is disposed on the top surface of the body and is located at one side of the clamping mechanism. The robotic arm is connected to the installing base and is adapted to clamp a bow. The stopping mechanism is connected to the clamping mechanism and above the violin. The control system is disposed in the inner space and electrically coupled to the bow-waving mechanism and the stopping mechanism.
The preferred example of the present invention employs a side-mounted six-axis robotic arm with a maximum load of 6 kg and a flexible end-effector that holds the bow and has a force feedback function. The string mechanism is an array device with an innovative chord function.
This invention can be combined into a chamber orchestra, and there are currently no similar works in the world. In addition to entertainment, the present invention is also applicable to trade shows, department stores, hotels and other industries, and can be used to attract customers and achieve the effect of promoting commercial activities.
