Sony's Rebooted Robot Dog Will Fetch Ruffly $1,700

Sony shares rose more than 11% on Wednesday to a nine-year-high. The new Aibo features improved artificial intelligence software and enhanced motors and sensors that help the robot better resemble a real dog. The company said each device will develop unique behavior patterns depending on owner interactions and can work with other internet-connected electronics. The Aibo will be released first in Japan and cost ¥198,000 (about $1,700). New owners will also need to pay about $25 a month for cloud services to provide their devices with remote updates for things like teaching the robot new tricks.
