Pamphleteer, aka "Little Brother," is a propaganda robot which distributes subersive literature. Pamphleteer is designed to bypass the social conditioning that inhibits activists' ability to distribute propaganda by capitalizing on the aesthetics of cuteness. The robot's form references a tradition of robot aesthetics developed in science fiction and popular media.
They also have robots that do sidewalk graffiti and roadway stenciling of your urgent subversive text.
