My wife bought a $300 Lego Mindstorms kit but my 3 year old didn’t have the dexterity to put together the blocks and the programming interface was a little above her level. Your kick-starter says that your link bots can be controlled just by tilting a connected module or using a phone. Is it really that simple? These things look big and easy to handle, are they kid friendly? She sometimes still puts things in her mouth, so I’m trying to avoid small parts (Lego’s were a terrible idea). Plus, it seems like two link-bots costs about the same at a typical Mindstorms set.
I was at maker faire and I saw a bunch of young kids playing with the linkbot. It seemed like most of the accessories were large enough to not be a big choking hazard either. I think that as long as you have the right set up the linkbot would be a lot of fun.
