Watch the video of CAM in action.
Looking to add some monstrous fun to school pep rallies and football games, Richard and three friends working toward engineering degrees at Colorado State University decided to create a robotic mascot. Controlled by two microcontrollers, "Cam the Ram" awaits input from a normally open button or an amplified condenser microphone. The triggering of either input sends Cam through one of four "routines" involving several counted actions that include blinking lights, an LCD screen, a fiber-optic pom-pom, and a speaker.

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
