This is Zobor, one of the three original Zeroids released, the other two being Zerak and Zintar. These were later joined by Zogg, who was initially part of an action set, and Zemo, who was made up of parts from the original three.
They also came with two additional hands, one was magnetic so the robot could carry small metal objects. The other was a missile launcher using the robot’s spring loaded arm.
The storage cases of the three original Zeroids had other uses. Zobor had a ’Cosmobile’ used for transporting light objects. Zintar had a Lunar Sled, and Zerak had a control station.
Made by the Ideal toy company, the original Zeroids were released in 1968.
Here’s a short film showing Zobor in action.
