Six caterpillar automatons are known to exist, but only two have diamonds, rubies, turquise and emeralds. One of them was sold for $415,215 at Sotheby's in 2010.

It was the Swiss textile manufacturer's fourth robot (he made the first when he was only 12!). It could move, walk, talk, sing and... yodel with the help of his twelve electric motors and an ultra-short receiver.

Eric was made by A. H. Reffell, a motor engineer, and Capt. William H. Richards, a WWI-veteran, to open the Exhibition of the Society of Model Engineers in The Royal Horticultural Halls, London. The aluminium Eric was able to speak, tell the time, shake hands, sit down when told, look around, and gesticulate. He worked with a 12V electric motor with some electromagnets and three miles of wire.

Dr. Motor from Hungary by Ferenc Tarján (1929) and an unknown automaton from 1937

The Charlie Chaplin-lookalike robot, Dr. Motor, was in a big store for years in Budapest to answer questions about anything. It could gesticulate and look around, but of course it wasn't able to think: a big loudspeaker was included on its chest, and a local comedian spoke through it. Some people believed that Dr. Motor was a real talking robot, and they loved to ask incomfortable and nosy questions like "Have you seen Budapest by night?" and "Do you have a lover?".
