These lecture notes introduce students to research on classifying linkage systems which involves a variety of ideas such as Assur groups, Baranov trusses, and Rigidity theory. Organizing the increasing complexity of machine systems to guide inventors has attracted researchers for literally generations and has generally been called “Type synthesis.” The goal is to provide a systematic way to explore the types […]

UCI, Vital Link and Orange County high schools and colleges are working together to organize a Rescue Robotics event in May of 2015. The Rescue Robotics challenge provides an opportunity for students in information and communication technology programs across Orange County to test their skills using ground and aerial robots to find and identify simulated […]
The ATHLETE Rover is a mixture of a wheeled rover and a walking robot, or better a walking truck, created by engineers at Jet Propulsion Laboratory to be used for manned and unmanned missions to the moon. ATHLETE, which stands for All-Terrain Hex-Limbed Extra-Terrestrial Explorer, is a six-legged walker that is taller than a person. […]
BYU Professor Larry Howell studies lamina emergent mechanisms, in other words, machines that emerge from flat pieces of material. If you think about the subtly complex movement of a children’s pop-up book, the way a page elegantly untucks itself to display a scene and then tucks itself back in, you wouldn’t be too far off. […]
Professors Carlos Castro and Haijun Su have developed what they call DNA Origami Machines and Mechanisms to pave the way for new small scale devices that could revolutionize medicine, manufacturing, and environmental sensing. DNA Mechanisms made from links of relatively rigid dsDNA bundles joined by soft ssDNA strands have the potential to provide machines for […]
The MechGen iPad App helps you design a link that connects an input crank to the coordinated rotation of an output crank. Locate the two cranks and define their input and output angles and let MechGen FG design linkages for you. The design data and an animation of your linkage is easily distributed by email. […]
A design problem that engineers frequently encounter is a curve that changes shape. For instance, take a spoiler on a high performance car. To get optimal performance, the downward force should be increased as the car takes a turn. An ideal way to achieve this is to allow the spoiler to change shape. This is […]
Training people to diffuse landmines and other live ordnance left behind in conflict areas has always been a difficult thing. Successfully training Explosive Ordnance Disposal (EOD) Technicians requires hands-on education that gives the technician a true understanding of how a triggering mechanism inside live ordnance actually functions. For this reason, this kind of education requires […]
Wearable electronics or “wearables” are seen as the next great wave of technology and commerce. Much of the popular talk about these kinds of products revolves around things like fitness trackers, augmented reality devices, and other machines you can wear that interact with, track, or add on to your experience with the world around you.
