Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Redefining the project by looking at larger tanks
Determining tank parameters to test and compare
Design possible designs and modification for treads
Accomplishments from Previous Week
Literature review on treads and wireless communication
Physical testing on a variety of tethers
Revised tether model based on tether tests
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Source the new larger tank
Perform scaleable testing to determine the tank's performance. (Katie, Yazeed, David)
Purchase large piping and soil for future testing (Katie, David)
make a CAD for pipe test configuration (JiuQi)
Modify the Tamiya tank for further testing.

Improve traction
Encouraged buying a larger tank, testing in larger tubes. This helps quantify our tests for traction and pulling better. The data will hopefully be scaleable and useful in designing smaller tanks.
Possibility of 3D printing custom treads design/modification?
Finalize tether findings
Determine cable parameters the contributes the most tension is difficult, so maybe a general qualitative approach is better. Trying many different tether samples and trying to draw conclusions.
Consider purely recovery tether if fully wireless communication is used.
We still want to validate the model by pulling tether through a PVC pipe and find possible deviations
Is spooling feasible? Try to answer this without knowing fully the size of components going on the tank. Stay theoretical.
How to experimentally quantify those two things
Make documentation more detailed so replication is easier
Design artificial burrow testing tube (adding dirt)
The pipe needs to take in the new vehicle
Can just use PVC piping for tether test for model
Derive a mean to place soil inside the pipe for testing
Ian: tank design could be applied to other burrowing animals besides just burrowing owls

Idea: adding studs to tank for traction
Research maximum ground pressure and sinkage: what’s the maximum weight that could go on the tank.
This would hopefully increase traction.
