At the Pack Expo West show in Las Vegas next month, Danaher Corp. will be making its first major product announcement since it went on a buying spree a few years back, acquiring well-known companies in the motion arena like Pacific Scientific, Kollmorgen, and Warner Electric. These former competitors got together, and using their collective engineering acumen, developed a new brushless servo motor, known as the AKM line, which will be marketed under the Kollmorgen label. What's notable about the new motor? For one thing, it's leveraging technology that Pacific Scientific originally developed for the Segway—one of the most challenging apps for motors around, say company engineers. But that's only part of the story. "One goal was to try and get as much torque as possible in the smallest possible package," says John Stroup, Group Executive, Danaher Motion. Stroup says that in tests against competitive motors, the new AKM exhibited about 30% higher torque density. He wouldn't reveal exactly how engineers did it, but it's likely they played games with windings, magnets, and slot fill. Another goal was to develop a cell-based manufacturing strategy to make up to 12,000 different versions from a standard motor platform. The strategy reduces the likelihood that an engineer will need to order a custom product, avoiding any additional charges, says Stroup. He also expects lead times to drop significantly.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
The DDV-IP is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the user.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
