Two of the robots pictured here were created by researchers at the University of Sheffield. AnTon, made by Dr. Robin Hofe, is an animatronic speaking robot that is used to study the mechanisms of speech production. eMo, made by Prof. Noel Sharkey, is capable of sensing its environment and displaying emotions. The images are clear glass ambrotypes, made by the wet collodion process.
There are also a few images of toy robots made with wet collodion and dry plate processes. I call them “tin toy tintypes”.
