item #ET-18 by Heathkit

image missing

Begun in 1979 and released in 1982 as an educational tool by Heath, a division of Zenith, I got my first glimpse of this fantastic piece of engineering on the Mr. Wizard's World television show on Nickelodeon. From that moment, I have dreamed of owning one of these.

I understand from my research on the internet that, when Heathkit ended support for the Hero robots, the remaining stock and all rights were sold to a company called Mobile Ed Productions. Inventory, documentation and rights were then sold to Robert Doerr of RobotsWanted.com in 2002. I am, therefore, unable to obtain either owner or technical manuals for these robots in downloadable format. In the future, I hope to be able to offer this service to you for free. In the meantime, any documents will have to come through him or eBay...

If you have any documentation not copywritten by Heath / Zenith or any old advertisements that you would like to share, please email me so that we can add them to this site. Of course it goes without saying that you should also contact me it you have any of the Hero family robots (working or not) that you would like to part with. I would REALLY love to find a kit!
