Deployable archway
This animation of Jerome Choe’s concept for a spherical archway was generated by Mikhail Zhuk. Spherical rhombus elements form a foldable structure. (UCI Robotics and Automation Lab)
Stackable fold-up emergency shelter
Mikhail Zhuk animated this design concept for an eight-bar linkage to deploy a collapsible emergency structure. A physical prototype is under development. (UCI Robotics and Automation Lab)
Elementary Robotics
The basic properties of robots can developed by studying planar serial chains. Select this link for my notes on elementary robotics: http://synthetica.eng.uci.edu/mechanicaldesign101/McCarthyNotes-5.pdf
CMU’s Introduction to Mechanisms
Yi Zhang, Susan Finger and Stephannie Behrens have prepared an on-line introduction to mechanisms consisting of eight chapters and almost 100 figures. Access it at the link: http://www.cs.cmu.edu/~rapidproto/mechanisms/tablecontents.html
Four-bar linkage analysis: Slider-crank
The slider-crank is an important mechanism with a wide range of applications. Here are my notes on its kinematic analysis. http://synthetica.eng.uci.edu/mechanicaldesign101/McCarthyNotes-3.pdf
Four-bar linkage analysis: 4R quadrilateral
The four-bar linkage is a basic machine component. It comes in two primary forms the 4R quadridlateral and the slider-crank. Here are my notes for the analysis of the 4R quadrilateral. http://synthetica.eng.uci.edu/mechanicaldesign101/McCarthyNotes-2.pdf
DC motor torque and power

DC motor basics
The basic principles of DC motors are presented by Joe Wolfe of the University of New South Wales (Sydney, Australia) at the link: http://www.animations.physics.unsw.edu.au/jw/electricmotors.html Northwestern University (Chicago, Illinois) presents the basics of a DC motor in the Wiki page: http://hades.mech.northwestern.edu/index.php/Brushed_DC_Motor_Theory
Mechanical Properties of Steel
The MatWeb site provides detailed information about materials such as the tensile strength of various compositions of steel. For example the search “low carbon steel” results in the list of links to information: http://www.matweb.com/search/QuickText.aspx?SearchText=low%20carbon%20steel
