ideal zeroid robot: zobor (date unknown)
Here's another robot from the late '60s/early '70s toy line from Ideal, the Zeroids. Each toy scooted about on motorized treads. Zobor's early box was cleverly designed to add to the play value - the robot could pull the box along on its wheels, carrying cargo like a wheelbarrow. The robots came with different hands (some magnetic) and a variety of accessories.
One of my school buddies had this specific Zeroid, and I coveted it fiercely. I managed to pick up this one years later on eBay, and other than some missing accessories and paint wear, it's in good shape. eBay is really the only place to buy one of these, and examples in decent condition start at roughly $70-$100 each. The more complete it is, of course, the more it'll cost!
