The goal of this test was to determine the accuracy of the 9DoF sensor in calculating the applied force needed to counter the effects of gravity while the chair is at an angle. To accomplish this a test code was run with the 9DoF sensor which used the measured angle and the mass of the chair to calculate the force of gravity pulling the chair down the ramp. With this code running, the chair with the test dummy was placed on the test ramp at a set angle. A spring scale was then attached to the front of the chair and used to hold the chair in place thereby measuring the force needed to counter the force of gravity at that angle in newtons. This value was then compared to the value produced by the 9DoF sensor and the test code. This test was repeated for several angles to ensure consistent results. It was found that the test code was capable of calculating the force needed to counter gravity within the goal of 10N of maximum error.
