Robot Learning to Walk: Advancements in Rehabilitation and Leg Injury Treatment

Scientists have created a robot that learns to walk like a toddler, improving its steps and balance with each stride. Funded by the National Science Foundation, this innovation aims to enhance rehabilitation techniques and devices for those with leg injuries. The robot employs a passive dynamic design, mimicking human walking by using gravity, springs, and motors, which requires minimal energy.

In what way does the robot improve its walking ability?
