South Korean robotics company Robotis is well known for their Bioloid line of robotics kits, but the firm is also positioning itself as a provider of robotics platforms for the educational market. Their new Ollo product line is a constructable robot kit aimed squarely at young robot builders, specifically those aged 7 to 10. That positions the Ollobot neatly underneath the LEGO Mindstorms NXT, which LEGO has positioned primarily for the 10+ audience.
The Ollo range currently consists of three products: The Ollo Bug Kit (~$99 USD), which includes a programmable module (the CM-100), a motor, an IR receiver, wireless controller and a host of plastic elements; the Ollo Action Kit (~$30 USD), which provides an electric motor and more plastic elements; and the Ollo Figure Kit (~ $20 USD), which just includes plastic building elements. Robotis has also developed some educational materials around the Ollo, which you can see an example of here.
