CES 2018 kicks off with oddball gadgets

Personal robots are learning more tricks, but they're still figuring out how to be truly useful.

Buddy is tiny, cute, and supposedly able to keep an eye on grandma, teach the kids math, and even catch a burglar.

The rolling robot from Blue Frog Robotics is crammed with the trendiest new tech like voice-control, video calls and assistant features. Blue Frog is also asking developers to come up with their own apps for Buddy.

The company has tested and demoed Buddy for years, but is getting ready for an official launch soon. The price will be about $1550.
