New micro brushless motors from Sanyo DC Micro Motor Division feature a ceramic air bearing design and frictionless, quiet, high-speed operation. The design eliminates the need to lubricate with oil, which tends to break down over the life of the motor. A 20 mm-size motor is available, with a 14 mm-size model to come. The motor has already been applied in a rear projection television color wheel, because it runs at high speeds and temperatures and is very quiet. It is also suitable for medical applications requiring high-reliability where an out-gassing oil bearing might cause an unacceptable level of contamination.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
