Active motor assistance means that the exoskeleton is equipped with its own motors that actively help the user with movement. These motors, technically known as actuators, generate force and supplement or replace human muscle strength. The system operates based on sensors that detect the user's intention to move. Once the sensors detect a signal, such as muscle tension, the exoskeleton's control unit activates the motors that perform or support the given movement. The goal is to reduce physical strain, increase the wearer's strength, or enable movement for people with mobility limitations. This is in contrast to passive systems, which do not have their own motors and use only springs or dampers for support, for example.
