Now a day’s MEMs (micro electro mechanical) devices took very good market in the day to day life products. Out of these MEMs devices Accelerometer is one of most popularly used device. The accelerometer can measure static or dynamic acceleration. In static acceleration it can measure the tilt of the system to which it is connected and in dynamic acceleration it measures the acceleration of the system with respect to free fall acceleration. When the accelerometer is used for tilt measurement it gives the three analog value X,Y and Z. X,Y and Z is the tilt with respect to reference value.
In this project we are using a accelerometer to read the body gesture values and with these gestures we will control a rover. To have protection on control we are using a totally new concept of gesture password protection. In gesture password we will store a sequence of body gesture like we use a sequence of alpha-numeric values for our email-ids.A microcontroller is used to convert the analog value of the accelerometer and to drive the motors of the robot.
The rover is designed with differential drive mechanism to have low turning radius and can be travel on some of the uneven surfaces too. To avoid our body’s unwanted responses we also used some of the algorithms in our programming.
In future the project can be extended by using some surveillance camera and the mechanical rover structure to an all terrain vehicle. In that case we can use that model as Accelerometer controlled surveillance all terrain vehicle.
