We kicked off the week with testing our integrated prototype. We setup 5 tests, namely: precision, torque(ease of rotation), setup time, comfort and durability tests. During precision torque, each of our team members wore and used the device 7 times and we worked out standard deviation for pronation and supination. For torque test we attached a spring scale to the pushing rod and record the scale displacement at which the platform moves away from the zero mark. As for ease of setup test, we asked 10 random individuals try and set up the device on us with the help of instruction set we wrote
Based on the tests results we modified our CAD files files and printed out the new pieces to fix noted problems. We also learnt through drop test that hot glue was not appropriate to glue together our assembly so we screwed together the joints. We started to 3D print pieces for our high fidelity prototype and we assemble the prints as soon as they are done. i sew the nylon straps for latching our wrist and elbow clamps. I learnt the sewing from scratch and am so excited to have added a new skill on my job market.
On Thursday, we presented our bootcamp project for anteater enrichment device at Houston zoo. We got feedback on Friday and we were so excited to learn that they liked our ideas and posted recommendations on future improvements.
