Since 2003, the Complubot robotics group has carried out activities related to educational robotics with students aged 6 to 18 years.

Throughout this time, participants in these activities have experienced, proven wrong and learned much of what they were doing or trying to achieve.

Year after year the knowledge and experience was accumulating to get a way to design, develop and build robots.

Lottie Lemon is the expression of this effort, a whole set of experiences that will take you directly to the world of educational robotics.

A learning robot

Lottie Lemon is not intended to be the best solution to a specific problem, our goal has been to provide a simple, stable and very inexpensive platform to experiment.
