Scientists have designed a robotic onesie that uses tracking sensors to help struggling babies crawl

Crawling is one of the first signs of healthy development in babies. When a child doesn’t start to crawl before the age of one, it can signal development deficits. In some rare cases, it may be a sign of cerebral palsy (CP), a neurological disorder that severely impacts muscle strength and movement. Around 10,000 babies born each year in the US will be affected by this incurable illness that can cause delayed development of the brain, muscles, and motor skills.
