Problem Statement
To create a practical version of this animal powered strandbbeest out of everyday found materials.

Designing the Implementation Process
The design includes a 5 inch animal running ball with two 10 inch supports on the side of the running ball. The sides of the running ball had 3/16 inch drilled into the sides and then a dowel, 3/16 inch, was inserted through the holes that were drilled.





Test, Verification, Validation, and Certification
So far the animal ball seems to work and the dowel in the holes does not require glue in order to it to have a tight seal.

Quality and safety assurance
A problem could come out of the design because it is plastic and with the holes drilled on the side along the line of where the two halves of the sphere are pieced together could crack with the pressure exerted by the wooden dowels.

Possible implementation process improvements
A better idea would be to use the drill bit that was originally used, 3/16 inch, and heat it up to the point where it could easily burn a hole through the plastic just by simply pushing it through. The heat would cause the plastic to bond around the hole and help prevent it from cracking with pressure.

Next Steps
The next step was to build a functional prototype of one of the strandbeest legs and showcase how it worked. However, this did not happen. The popsicle sticks close together created a lot of friction and so duct tape was used to lessen the friction and stop the popsicle sticks from cracking in half, while it did cut down the friction and the duct tape held it together, it started problems of its own. The head pins would not work in between the popsicle sticks and the duct tape so I used thumb tacks to really hold things together. and it provided a smooth surface for the stick to rotate around. The thumb tacks could only hold so many popsicle sticks and you cannot add another thumb to help hold the sticks because then it would not rotate properly. The design of the legs needs to be completely rethought or a better joint part needs to be used.
