1 feb 1969 anni - First Small, Electric-Powered Six-Axis Robot

Descrizione:

Unimate’s robots were large and powered by hydraulics, causing them to leak and thus limiting where they could be used. In 1969 Victor Scheinman designed a small robot arm with joints powered by electric motors embedded in the arm itself. The “Stanford Arm,” as it was dubbed when Scheinman built prototypes, could move much more quickly than previous robots, and without the mess of hydraulics. This opened the door for robotics to think about using robots in drier, indoor environments, or even on desks (the original prototype weighed only 15 pounds). It also had six axes of movement, or “six degrees of freedom,” allowing it to more closely approximate the range of a human arm. And it was the first robotic arm to be controlled not just by turn-by-turn instructions stored in memory, as with the Unimate, but by software in a computer. This meant that the Stanford Arm could perform calculations in real time and, in later iterations, react to its environment (such as with touch sensors or a vision system). The era of faster-moving industrial robots with fine-grained computer control was born.
