Decision ProcessMSD II Project Schedule
Build, Test, and IntegrateFirst test completed is the wood demo test with the actuator provided by Linak that will be used to power and operate the bath tub seat. In addition testing of the turn table that will be on the base of the seat to allow the chair rotate in the tub.

Test Plans & Test ResultsAfter testing with the wood demo, some weight was applied on top on the device which resulted in the rod attached to the actuator which helps with raising the legs deformed. After stress calculation it was agreed that a 3/4" 304 SS rod was needed. Wood Demo Dowel Bend
Waterproofing solutions were tested for the actuator. A Ziploc space bag was purchased and test with the actuator as well as a bellow. The bellow as a result had the best results for moving with actuator and keeping water out. Ziploc Space Bag Test
Suction cups were purchased by SeaSuckers and were tested on how much force they can take.
Seat and sliding component for the device were tested after being built and assembled. The rotating part had to have lubricant added to make rotating easier for the user.
Final Prototype4 Scissor legs were machined from 304 stainless steel using a water jet. Bushings and alloy pins were place in the middle holes to create the scissor concept.
An adapter was machined from milling and drilling to be attached to the actuator to push a rod that will be connected to the clevis. The clevis are mounted on to a carriage which are on rails to help slide and raise/lower the scissor legs.
