What to know

Bittle is a small, open-source robot dog you can build yourself or buy pre-assembled. It walks, does tricks, responds to voice commands and can be programmed with block coding, Arduino or Python.

It is a learning tool, not a companion pet: the appeal is building and programming it. That makes it one of the most popular robot dogs for teenagers, classrooms and adult makers.

Good for

Teens and adults learning robotics
