Claim Text:
1. A transmission device comprising: a timing belt transmission configured to cause rotation of an output hub, wherein the timing belt transmission includes a timing belt with conductive properties that wraps around an input hub and the output hub in a loop; a voltage source coupled to the timing belt to apply a voltage to the timing belt; a first detector positioned between the input hub and the output hub on a first side of the loop of the timing belt for detecting a given resistance of a portion of the timing belt as the timing belt is placed under a tension and stretches due to a load at the output hub; a second detector positioned between the input hub and the output hub on a second side of the loop of the timing belt for detecting a given resistance of a portion of the timing belt as the timing belt is placed under the tension and stretches due to the load at the output hub; and one or more processors for determining output torque of the timing belt transmission based on respective resistances of the timing belt output by the first detector and the second detector.
