Toys From My Childhood

Zerak toy robot
The Zeroids were a line of toy robots from the Planet Zero introduced by the Ideal Toy Companyin 1967 and re-licensed by Toyfinity in 2013 along with the later "STAR Team" revival. Consisting of Zerak, Zintar and Zobor, the Zeroids powered their way into the imaginations of young boys for nearly a decade. Zeroid robots were powered by a small DC electric motor that could be removed. These DC motors appeared as the brand name "Motorific" in Ideal Corp racing slot cars, and "Boaterific" powered scale motorboats.
The original sales pitch read, "Moving across the landscape, overrunning all obstacles as inexorably as the Future itself, these amazing, efficient and powerful automatons have but one purpose - to serve their masters at work and play!"
The storage cases in which the robots came could be used for other purposes. The robots were battery operated, and had wheels with rubber treads to propel themselves across the floor. There was a bottom mounted reversing switch that would allow the robot to reverse when it touched a special plastic plate, or turn the robot off, when in backed up into its display case.
Zerak, the blue robot, was originally the "commander" of the three robots. Zerak came with hook hands, and interchangeable magnetic hand and a throwing cup hand. Zerak's right arm could be cocked, and made to throw objects. [Wikipedia]
