1. Overview of Robotic Exoskeletons

Robotic exoskeletons are wearable machines that enhance or augment human physical capabilities. They are designed to be worn on the body, assisting movements and providing strength and stamina beyond natural human limits. Initially developed for military applications, these technologies have expanded into various fields, including healthcare, construction, and logistics.

The core principle behind robotic exoskeletons is to blend seamlessly with human motion. Sensors embedded within the exoskeleton detect the user's movements, which are then amplified or assisted by motors and actuators. This synergy allows users to perform tasks more efficiently, significantly reducing fatigue and the likelihood of injury.
