PM helped shave nearly 20 percent off the cost of a lawn mower blade-stop assembly, which won the grand prize in the competition's lawn-and-garden category. Previously, the assembly's drum and pulleys had been machined, cast and stamped. Burgess-Norton Mfg. Co. used PM to add features that ease assembly to the mower blade. Among them are a molded key on the pulleys and hexagonal pockets on the drum. The pulleys are also sinter bonded together into a single component. Burgess-Norton forms the parts to a density of 6.9 g/cm3 with an ultimate tensile strength of 280 MPa and an apparent hardness of 50-80 HRB.

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.
