An exoskeleton is a supportive outer structure that protects and gives shape to certain animals, like insects and crabs. Unlike humans, who have internal skeletons, these creatures have hard shells or coverings that help them survive in their environments. This outer layer not only provides protection from predators but also helps in movement. In recent years, scientists have developed robotic exoskeletons to assist people with mobility issues. These wearable devices can help individuals walk again or lift heavy objects, making daily tasks easier. By mimicking the function of natural exoskeletons, these innovations are changing lives and enhancing human capabilities.
