In the field of wearable robots, high power density and highly efficient actuators are required to handle the high power motion without becoming heavy and bulky and hence hamper their mobility. Typically, electrical motors are used in combination with high gear ratio gearheads or lever arms in order to achieve the required torques. These gearboxes consist mainly out of several stages of simple Planetary Gear Trains (PGTs). However, this approach leads to big and heavy gearboxes when high torque is needed. An alternative design to obtain the required torque increase can be based on the more compact design of Compound Planetary Gears (C-PGTs). It is shown that the latter mechanism can achieve a gear ratios up to 1:600 while withstanding an output torque of 100Nm.
