Petoi Bittle X vs Doly
Two robots for people who want to open them. One walks on four legs and comes as a kit; the other rolls on tracks and is a small computer you can reprint.
Which one to buy
Choose Petoi Bittle X if
you want a real legged gait, backflips, thirty-five voice commands and a curriculum to learn from.
Choose Doly if
you want a desk pet that navigates by itself, recognises faces on the device and can be rebuilt with a 3D printer.
Bittle X arrives as a kit and takes about an hour to build unless you pay for the assembled package, and it runs about an hour per charge. Petoi says ten and up, and a child under ten will need a grown-up. Doly is the most expensive desk robot here, expects tinkering rather than unboxing, and its development ran late after the crowdfunding campaign.
