Real-World Applications of Robotic Exoskeletons
What Are Robotic Exoskeletons?
Robotic exoskeletons are wearable devices designed to enhance human physical capabilities. They consist of a mechanical framework that supports and augments the user’s movements, often integrating advanced technologies like sensors, actuators, and control systems.
Key Components:
- Sensors: Detect user movements and environmental conditions (e.g., force, motion, bioelectric signals).
- Actuators: Provide mechanical power to assist movement (e.g., electric, hydraulic, or pneumatic systems).
- Control Systems: Manage the interaction between sensors and actuators, ensuring smooth operation.
Types of Robotic Exoskeletons:
- Powered vs. Unpowered: Powered exoskeletons use external energy sources, while unpowered ones rely on mechanical design.
- Lower-Limb vs. Upper-Limb: Lower-limb exoskeletons assist with walking or lifting, while upper-limb devices enhance arm and hand functions.
Understanding these basics is crucial for exploring their real-world applications.
