Case #87: Jason Was An Honorary Member of the Captain Nemo Fan Club

NO RATINGS

Inspired by 20,000 Leagues Under the Sea, Jason built this underwater Remote Operated Vehicle (ROV) so he, himself, could explore the depths of his bath tub, swimming pool and beyond. Employing mostly off-the-shelf parts, the ROV is controlled via Visual Basic commands sent over an RS232 serial port. Powered by bilge pump motors and equipped with a video camera, the ROV was developed on a flexible platform that will allow the addition of advanced capabilities such as joystick control, temperature/pressure sensors, air lift balloons, and sonar.

LATEST ARCHIVED BROADCAST
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
