The doors of the Koenigsegg CCX open using the “dihedral synchro-helix door actuation” system. You can see this movement on the video
Cambridge University provides a useful overview of materials properties such as the chart below.

Joseph Klann provided a useful comparison of the leg designs for the Mondo Spider and Theo Jansen’s Strandbeest at this unfortunately dead link: http://www.mechanicalspider.com/comparison.html. I keep in here in case he brings it back.
Here is an excellent web page about the Klann and Jansen leg mechanisms, as well as other leg designs: Dog Feather Designs.
This article compares the leg designs: Mechanical Spider Using Klann Mechanism
This is a youtube video prepared by William Thielicke that illustrates the two leg mechanisms.
This walking machine is known as the Mondo Spider. More information is available at Mondospider.com.
The leg of the mondo spider has the topology known as a Stephenson six-bar and is described in US Patent 6,260,862 awarded to Joseph Klann. Access it through the link:
Wikipedia calls this the Klann linkage which is described here:
Theo Jansen builds amazing walking machines.
Each leg is an eight-bar linkage. The Wolfram Demonstration Project models this linkage in a Mathematica notebook. See the link:
The National Institute of Standards and Technology provides an on-line periodic table. Access it and other information at the link: Periodic Table

This design concept is an 8-bar linkage developed by Minshan Tsai and GimSong Soh for my advanced mechanisms class lifts the top of a recreational vehicle to create a second story, UCI Robotics and Automation Lab. It is on YouTube:https://mechanicaldesign101.com/wp-content/uploads/2009/04/rv-overhead.mov
This linkage to lift the lower rack in a dishwasher was developed by Marshall Meek in my advanced mechanisms course (UCI Robotics and Automation Lab) It is accessible on YouTube:
