Prof Haijun Su at Ohio State University had his students design walking machines for their final project in ME 5751. Here are videos of four project teams from that event.

Team B:
Team C:

The linkage design software developed by Art Erdman and his students at the University of Minnesota, called LINCAGES: Linkage INteractive Computer Analysis and Graphically Enhanced Synthesis Package, was developed in 1977 through 2000. This is a link to his information site. His guide map that evaluates all of the linkages formed from points on the circle-point and counter-point curves was a nice innovation.
This link connects to a YouTube video shows the linkage design process using LINCAGES:
Just after I published my book Kinematic Synthesis of Mechanisms with its emphasis on leg mechanisms, I found two more interesting eight-bar legs from the designers at DIYWalkers.com
This is a Geogebra animation of the leg mechanism for the Strider walker. It is a symmetrical design that allows the formation of a second foot assembly by simply adding two more bars.
This is an animation of the leg mechanism in the TrotBot walker.
The animated four-bar linkage FHJD is constructed using dimensions as the quadrilateral ABCD. The dynamic geometry software Geogebra maintains the dimensions of FHJD as the points of ABCD are moved. The result is that the animated linkage changes to match the new dimensions. This can be seen in following Movie. For more information see Kinematic Synthesis of Mechanisms.
Here are the eight Movies in Chapter 6 of Kinematic Synthesis of Mechanisms.
Here are the four Movies in Chapter 5 of Kinematic Synthesis of Mechanisms.
Here are the four Movies in Chapter 4 of Kinematic Synthesis of Mechanisms.
Here are the four Movies in Chapter 3 of Kinematic Synthesis of Mechanisms.
Here are the six Movies in Chapter 2 of Kinematic Synthesis of Mechanisms.
Here are the three Movies in Chapter 1 of Kinematic Synthesis of Mechanisms.
