Too many robot designers assume that their products will be operating with little human contact. So claims a team of NASA engineers who have devised a procedure to assure that safety as well as performance is stressed in the design of robots. The methodology involves five main steps and a number of subsets. For a given application, the procedure assigns minimum acceptable values for performance specifications, such as robot-tip velocities, payloads, position, force accuracy, and dexterity. It also provides values for safety requirements, for example, robot static and impact contact force, pinch forces, and crushing forces from robot weights. For a description of the procedure go to www.nasatech.com and access the Technical Support Package under the Machinery/Automation category.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
