The Flowing of the Dao

Motoman DA20

The DA20 dual-arm robot provides high-speed motion with two six-axis arms that provide enhanced, “human-like” flexibility of movement, opening up a wide range of applications to be performed by robots. This revolutionary, innovative design makes the DA20 robot ideally suited for a wide variety of assembly, packaging, part transfer, machine tending and other handling tasks that formerly could only be done by people. The unique DA20 features 13 axes of motion (six axes per arm, plus a single axis for base rotation).

The DA20 robot has a 20 kg (44.1 lb) payload per arm, a 765 mm (30.1″) reach per arm (from centerline of base rotation to tool mounting surface), and a repeatability of ±0.1 mm (0.004″). Both robot arms can work together to double the payload or accomplish intricate tasks. In addition, both robot arms can perform tasks independently without degradation of throughput. The DA20 robot can also transfer a part from one of its arms to the other with no need to re-grip the part. It also provides “jigless” operation, allowing one robot arm to hold the part while the other performs the required process(es).

Basic Fire Control Mechanisms, OP 1140, 1944, describes the mechanical computing elements used in U.S. Navy fire control systems. These components are the building blocks of some of the most successful analog mechanical computers ever built.

Thanks, Gene.

Providing a taste of what third-generation sequencing might look like, Pacific Biosciences last week outlined its single-molecule real-time, zero-mode waveguide DNA-sequencing technology, and its progress to date.
