LAS VEGAS - Evollve Inc. showed off Ozobot Bit Sunday night at CES Unveiled. This 1-inch robot can sense colored lines, detect patterns such as intersections, read flashing light codes, and play back up to 500 commands. It's also programmable using a color-based code language and a block-based programming editor. The company is aiming it at kids as an interactive tool that can teach them programming skills by allowing them to make their own courses for Ozobot Bit to follow, or by making their own games. The device also interacts with an Android and iOS app. In the included image, several Ozobot Bits are following paths that cross from tablets to hand-drawn paper and back again. Ozobot Bits are shipping now for US$49.99 for one, or a two-pack for $99.99.
