Bionic Limbs - Science of Innovation

In the Robotics and Human Engineering Lab at UC Berkeley, Dr. Homayoon Kazerooni develops robotic exoskeletons to help people with paralysis walk again. Inspired by humanoid robots, Kaz's work in bionics mimics human movement using lightweight motors and computers. Volunteer Steven Sanchez, paralyzed from a BMX accident, uses the exoskeleton to regain mobility. The lab also explores other mobility innovations and emphasizes the importance of patents for sharing and protecting ideas.

What is the primary purpose of the robotic exoskeleton developed at UC Berkeley?

• To improve military capabilities

• To enhance athletic performance

• To assist people with paralysis in walking

• To aid in construction work

What inspired Dr. Kazerooni to develop the exoskeleton?

• A science fiction movie

• A government project

• A personal injury

• Observing humanoid robots

In the exoskeleton, what acts like the human central nervous system?

• The lightweight motors

• The battery packs

• The carbon fiber leg braces

• The computer

How does Steven Sanchez control the exoskeleton?
