Taking care of a baby is such a pain, what with all of the personal attention it demands. Luckily, this robotic crib does the heavy lifting for you.
The Suima crib, developed at Kyuushuu University in Japan, is designed to rock your baby to sleep if it wakes up crying. It does this by sensing cries using a microphone. When detected, the crib starts to sway side to side every 1.8 seconds, or about as fast as a parent's heartbeat. Apparently, this speed helps lull the infant back to sleep quickly.
The crib is available for rent in Japan for about $100 per month, or you could buy one for between $4,500 and $5,500. [CrunchGear]
