I'm trying to remember what these toys were.

I remember they were little vehicles that were either programmed to specific tasks or they were controlled by RC but I can't remember.

They collected balls around the field.
One looked similar to a cement layer vehicle but it was a brush instead of a stolid wheel.

Another one was like a bulldozer, another one had a vacuum type setup I think and another had a crane.

I think they were all yellow and around the size of a large crayon box.


Similar styling to pic related but it wasn't lego.
I think they had specific proprietary battery packs and charging stations.

Only knew 2 richfag friends who had them.
