Automated treadmill that adjusts speed as you run
For runners, here comes a treadmill that automatically changes speed to match the pace of the runner. The automated treadmill uses sonar technology to tell exactly where the runner is on the treadmill. If the runner picks up pace and moves toward the front of the running belt, the speed automatically increases. If the runner slows down and moves toward the back, the speed decreases.
New York: For runners, here comes a treadmill that automatically changes speed to match the pace of the runner. The automated treadmill uses sonar technology to tell exactly where the runner is on the treadmill. If the runner picks up pace and moves toward the front of the running belt, the speed automatically increases. If the runner slows down and moves toward the back, the speed decreases.
The researchers started with an inexpensive sonar range finder which is used to measure the distance between an object and the sonar device. They attached it to a microcontroller and a computer, which was linked to the electronics in the treadmill. The sonar is set up behind the treadmill and aimed at the runner's back, just between the shoulder blades. The speed increases until the runner returns to the middle of the belt.
