What a weird and wonderful history we have.
In 1929, we had a robot dog that would chase a light and bark. 1929. It was almost 20 years after that (1947) before we had transistors....Philidog, a French robot exhibited at the 1929 International Radio Exhibition in Paris. Philidog would follow a specific light obediently, and when it got too close to the glow, would stop and begin to bark. A decade later, the Sparkos were meant to upstage the French. All the Sparkos were modelled on Scottish Terriers and meant to be shown off with their master, a smoking robot, at the 1939 World's Fair. They were supposed to follow any light, and chase after visitors playfully....the first to perish died tragically before the Fair even began, when a careless worker left the door to its storage area open. According to sources at the time, a car passed the door. Immediately, the dog saw its headlights. Off it went. Apparently it, 'rushed headlong towards it and was run over, despite the efforts of the driver to avoid it.'
