| 摘要 |
The present invention provides a sensing ball comprising a ball body on which several sensors (2,4,5,8) are mounted, and in the ball body are mounted motors (17,35), an eccentric device driven by the motor and a controller for controlling rotation of the eccentric device, in which the sensors are connected to the controller. When a moving object approaches the sensing ball, the sensors generate sensing signals and input the sensing signals into the controller, and the controller controls rotation of the eccentric device and drives the ball body to roll back and forth in a specified direction or keeps it static based on the sensing signals. The sensing ball according to the present invention can realize a relatively strong interaction with a moving object, for example, when a child approaches the sensing ball, the sensing ball can move away from the child, therefore stimulating his/her curiosity and attracting him/her to walk or crawl so that the child may learn to walk or crawl in this way.
