Robotic exoskeleton

Robotic exoskeletons are wearable devices that enhance human strength and endurance, with applications in medical rehabilitation and industry.

About this subject

Robotic exoskeletons are external mechanical structures that attach to the human body, providing motor support or force amplification. Originating from military research in the 1960s, such as General Electric's Hardiman, recent advances in sensors, actuators, and batteries have made commercial versions viable. In medicine, exoskeletons like the EksoGT and ReWalk enable spinal cord injury patients to walk again, while models like the Indego are used in rehabilitation clinics. In industry, devices such as the EksoVest and Hyundai Vest assist workers in repetitive tasks, reducing strain injuries. Technology is divided into rigid exoskeletons (with metal frames) and soft exosuits (fabric with cables), each with specific advantages. In Brazil, research at USP and Unicamp develops low-cost exoskeletons for rehabilitation. The global market grows at 30% annually, driven by aging populations and industrial automation.

Frequently Asked Questions

How much does a robotic exoskeleton cost?

Prices range from $50,000 to $100,000 for full medical models, while industrial versions may cost between $20,000 and $40,000. In Brazil, values are higher due to import costs.

Can exoskeletons be used by able-bodied people?

Yes, especially in industry to reduce fatigue and prevent injuries. There are also prototypes for military use, enhancing soldiers' load capacity.

What is the battery life of an exoskeleton?

Most models operate for 2 to 4 hours on a single charge, depending on usage intensity. Research aims for solid-state batteries to extend this time.
