Human Arm Model
Extension As the tricep muscle cord is pulled with a Force Sensor, another fixed Force Sensor records the tension in the bicep muscle cord.
Human Arm Model
Curl
As the bicep muscle cord is pulled a short distance, the end of the arm moves through a very large distance, showing the mechanical advantage of the arm. The load at the end of the arm can be varied.

Free Throw
To perform this motion, an elastic cord is used as the bicep muscle cord and the tricep muscle cord are pulled with a Force Sensor. The motion of the arm and the release speed of the ball are measured with the built-in potentiometers using the Angle Sensor.

Angles and Forces During Extension: The upper graph shows the angles of the elbow (violet trace) and the shoulder (blue) as the arm is extended. Shown in the lower graph, the bicep tension (red) has little change at first and then rises sharply as the arm reaches out, while the tricep tension (green) rises steadily.
