Here are videos of the designs for the four legged mechanical walkers obtained by Teams 1, 3 an 6. This is the final project in my Fall 2019 Kinematic Synthesis course. Team 1 Team 3 Team 6

This video shows how the linkage systems moving spooky decorations designed by my six student teams were combined into a Halloween display.
The Halloween decorations designed by project teams 4, 5 and 6 can be seen in the video
Students in my MAE 245 Advanced Kinematic Synthesis class have designed Halloween decorations using a four-bar linkage by itself or in combination with a parallelogram or pantograph linkage. You can see the work of teams 1, 2 and 3 in the video:
Here are the solid models of some of the walkers designed by UC Irvine students in my Spring 2019 course MAE 183 Kinematic Synthesis of Mechanisms. Walker Group 1 Walker Group 2 Walker Group 4 Walker Group 6 Walker Group 8 Walker Group 9 Walker Group 10
This is an animation of the leg mechanism for a mechanical walker designed using function generators to drive the hip and knee joints. A second parallelogram linkage is used to construct a translating leg that allows placement of the foot trajectory where ever the designer chooses.
This is a series of four videos that show how to: Specify three positions for the foot of a leg consisting of a hip and knee joint; Use three position synthesis to design a four-bar function generator to guide the hip joint; Then use three position synthesis to design a second four-bar function generator to […]
The graphical construction of a four-bar function generator that coordinates three input and three output angles is presented in the video below. It is possible to coordinate as many as five input-output angles, but this requires numerical calculations using software like our MechGen FG iOS application. More notes on Kinematic Synthesis Also see my book Kinematic […]
Our MechGen FG iOS application provides five position synthesis for four-bar linkages. A Demo of the iPad version is provided below. It is also available on the iPhone.
The graphical construction of a four-bar linkage that coordinates two positions of an input crank with two positions of an output crank is presented in this video using Geogebra. A linkage that coordinates the values of input and output angles is called a function generator. It is possible to design a four-bar linkage to coordinate […]
