Considering that the present motion-sensing games can only realize a virtual experience

a motionsensing controlled two-wheel self-balanced fighting robot is designed. The robot is designed on the basis of twowheel balanced car

which has the characteristics of flexibility

celerity and stability

making it possible to replace legs of ordinary robots. The motion-sensing part is composed of 13 MPU6050 sensors

of which 12 of them are equipped on the controller’s arms and one on the waist. According to the launching angles of each MPU6050 sensor

the sampling sites are labeled on controller’s arms. And then by Lagrange’s Interpolation Polynomial

controller’s attitudes can be detected. Through wireless serial port

information of controller’s attitudes are sent to robot so as to realize robot control. The designed two-wheel self-balanced fighting robot possesses the features of drivability

high stability and strong entertaining.
