I remember all of those except the Arctec Gemini. There were also some noteworthy lower-end toy robots, like: https://en.wikipedia.org/wiki/Big_Trak https://en.wikipedia.org/wiki/Big_Trak https://en.wikipedia.org/wiki/Armatron https://en.wikipedia.org/wiki/Armatron Less-known were electronics parts mail-order catalogs with sections of assemble-it-yourself small robot kits (not much more than a PCB, components to solder, and some motors), like: light-seeking robots, line-following robots, Logo-style turtle graphics pen robots. And occasionally a magazine would have an article a homebrew robot that some teen had built. To kids with access to scrap wood, garage sale appliances to strip for parts, and the occasional Radio Shack or mail-order component purchase, these homebrew robots seemed more accessible than ones costing hundreds or thousands of dollars.
