I have used this one: https://www.poppy-project.org/en/robots/poppy-ergo-jr https://www.poppy-project.org/en/robots/poppy-ergo-jr but not with kids around. It is nice for makers as you get to build it and can modify its shape. It is a basic arm but with 6 motors you get more cool movement out of it. And it is controlled via a RPI and is all open source which I like. But for kids I don't know if the age target is suitable, the project targets education https://www.poppy-project.org/en/education/ https://www.poppy-project.org/en/education/ with visual programming and activities but I never tried..
