Problem Statement
Need to build The Jansen mechanism using household objects.

Work flow

 * Research: Googled how to build Theo-Jansen mechanism. Found a site with PDF and tutorial on how to build out of wire and paper.
 * Preparation: Straightened coat hanger to be used as wire. Printed plan on photo paper because it's stronger than normal paper. Cut the paper into appropriate pieces. Went according to plan. Noticed potential problem is paper may be too small for coat hanger, also may have to make smaller angles.
 * Construction of Camshaft: Analyzed tutorial. No needle-nose pliers to make angles from wire, had to use wrench, which worked. Bent wire to make camshaft. See video for angles. Hard to keep spacing consistent.
 * Construction of Hubs: Made hubs out of cut-up pen tubes. Attached hubs to camshaft.
 * Construction of Legs: Began assembling legs, but were too flimsy. Created legs out of strong folder paper. Used razor to cut legs out of folder, folded and glued legs into triangles, and attached legs to hubs with tape.

Test, Verification, Validation, and Certification
Tested and legs move but not very well. Haven't added other wire. Camshaft angles are off, and possible too big.

Possible implementation process improvements
Make angles on camshaft precise and small.

Next Steps
Reconstruct camshaft smaller with more precise, sharper angles.
