The fully rotating head mounted on top houses the single eye and sensors, together with a spotlight and basic communicator with a cheap voice synthesizer, short range radio, and communications jack. The barrel-like main body contains the Calpower 238B nuclear power unit (200 KW output with two year endurance comparable to a truck engine) and eight rechargeable energy cells with a 270,000 KWS output, together with an integral mechanic toolset and the computer brain. Handy has the distinct, lumbering appearance with easily identifiable sub-assemblies. The original General Atomics International Mr. The success of this model resulted in the development of several additional models, including dedicated medical and military versions. Despite its sophistication, it was also cost-effective, making it the perfect domestic servant robot. The resulting model was a sleek, elegant design capable of self-programming and initiative, more than making up for halving the number of arms to just three. In order to maintain their market share, General Atomics entered into a joint venture with RobCo Industries, combining its talent with General Atomics' experience in robotics. By the 2070s, it was an automaton surrounded by more advanced designs utilizing cutting edge neural networks. Handy was, it was still a design rooted in the technology of the 2030s, with a compact computer brain that was incapable of learning or executing complex tasks without extensive programming. However, as rugged and reliable as the original Mr. Handy was designed to perform its own nuclear fuel replacement and radiation cleansing, as well as carry out maintenance and repairs on other units (it was not possible for it to carry it out on itself). To minimize maintenance overhead, each Mr. The Calpower 238B nuclear power unit and self-maintenance modes were key to its success, ensuring each robot's longevity. So reliable, in fact, that it only received one major hardware update in 2039, to eliminate a bug causing interference in the operation of the multiple arms.

Used widely on both the American and Mexican markets (especially after the Mexico City earthquake of 2042), it was a rugged, reliable design. The first Mister Handy was introduced to the robotics market in 2037 by General Atomics International, as a general purpose construction and maintenance unit.
