1.we will make this project with 2arduino , 2 ultrasonic , 2 Zigbee tx rx , LCD and pc interface point and cable . 2. there will be a box of say 1meter by 1meter , position of the athlete will be sensed by both the ultrasonic , one placed in the front and other on the left side of the shoulder , we will place two ultrasonic on a wearable band , which can be put on the shoulder of the athlete. 3.there ultrasonic have a range of approx 2cm to 400cm , we will judge the same in a 100cm by 100cm box , just like shown in the image. 4. Just after getting the data of the details from front and side sensor , we will find the position of the athlete from the wall . 5. here instead of athlete we will use a small box for 5by5cm , on which the digital circuit will be placed and will run on battery. 6. data from the box will get transmitted to another Zigbee , which can be placed for near about 100mtr. 7. received data on 2nd Zigbee , will be decoded by the another arduino , can be shown for the PC .
