At Berkeley Process Control's Technology suite at the Semicon West Show this year, one of the main demonstrations featured a broken robot. How crazy is that? Turns out there was a method behind this madness, which was to showcase Berkeley's new BX motion controller. "The controller can detect a mechanical problem and automatically compensate for it, maintaining move or motion profiles regardless of the health of the robot," explained Mario Lento, senior product specialist, who was tending to the robot. "It enables even sub-par mechanisms to operate as designed." The controller works by maintaining velocity and position following information in realtime while the current (or torque) loop is closed to preserve the quality of the defined motion. That real-time state of the current (or torque) is known and incorporated in Berkeley's suite of In-Situ diagnostics. Lento explains that this state information is measured and controlled in a variety of ways to determine how much effort is required to force a sickly robot to comply with its required quality of motion. For robots in critical condition, say there is not enough torque to maintain the required profile, the controller will generate an error or report profiles outside the limits.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
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
