The school system where I am uses the Cutebot version with grades 1-8. I use the more complex robots at the high school.
These are my robots as of now.
These are the robots I have or will be testing and comparing.
The two that stand out in terms of using them in a high school setting and having advanced features are Cutebot Pro and Maqueen Plus V2. A third which is still in the box is the Maqueen Plus V3 and that one may be too much, too expensive, with too many built in functions to use for education. I don’t know yet.
At the back on either side are animatronic robots I am experimenting with. They are made of cardboard and could possibly be assembled by children. Maybe. I don’t know about those yet.
