If there ever needed to be proof that the Adept Quattro Robot is the fastest robot in the world, this is it!
This video demonstrates the unmatched speed of the Adept Quattro robot and technical achievements in robot system performance. This is more than simply motor speeds; to manage the robot doing this much in so little time takes a high performance motion controller, software, and electronics.

To the user this means increased product throughput, but not at the cost of control over the motions. Adept's SmartController CX and V+ programming language allow the management of the specific motions: speeds, accelerations and accel profiles, end-of-motion tolerances and behavior, etc. When manufacturers look at automation in a cost-per-pick analysis, being able to pick products faster and more reliably means an improvement to the bottom line.

The unique patented design of the Adept Quattro robot enables this level of performance with its four-arm parallel kinematic (known as PAR-4). This is differentiated from the three-arm delta style robots commonly seen in the industry. The four motors share the load and contribute to the motion, thus reducing the load on the individual joints and allowing greater speeds, higher payloads, and improved performance throughout the entire robots work envelope.
