摘　　要：介绍了一种用于残疾人的智能交互系统——头部动作识别系统的主体硬件框架,包括头部运动测量单元的设计,采用了三轴陀螺仪L3G4200D和三轴加速度传感器ADXL345。机械臂的执行器驱动单元设计,该部分采用MOSFET驱动,有电流反馈。机械臂结构设计,该部分采用线性执行器电动推杆,推力1500N,速度在2mm/s至60mm/s之间可控,行程200mm,机械臂底盘支持360度全向旋转,整体水平作用距离达1.2m,垂直作用距离1.0m,腕关节支持360度旋转,夹持机构开合行程30mm,可以应对一般家庭应用。为机械臂控制算法的工作提供了硬件平台。Intelligent interactive system based on head movements recognized for disabled people is introduced in this paper. Headmovement measurement module is designed with a 3-axis digital gyroscope L3G4200D and a 3-axis accelerometer ADXL345. Actuator of manipulator is driven by MOSFET. Motorized faders which is a kind of linear actuator is selected to drive themanipulator,the thrust of it can go up to 1500N, it can move between the speed of 2mm/s and 60mm/s controlled by MCU. The stroke can be as far as 200mm, the chassis of it can turn in 360 degrees. The level of the horizontal and verticaldistance is 1.2m and 1.0m. the wrist also can turn in 360 degrees. The stroke of the clamping mechanism can be as far as30mm. Generally speaking, it can qualified ordinary home use. Its feature satisfies the system need. The hardware designsupplies control algorithm with a stable platform.
