COVID-19 Continues

Since the lockdown has been placed on California residents, the Wayside Team will no longer be meeting in person. The project will be completed virtually on Solidworks. There will be no more work done on the physical project. Thus the project now has the capability to expand beyond previous budget limitations. The Wayside team will have the ability to aim higher since the project can't physically be built. More robust material can be used in the assembly. 

The mechanical team has decided to change the springs to constant force springs. Force sensors will be added. Adjustments will be made accounting for the wear on the contact shoe (Figure 1).

The electrical tabletop setup (Figure 2, 3) current flow issue has been resolved. The current flow issue we had previously was due to the power supply we were using. We switched out the power supply and now the system works.

The tabletop setup (Figure 2, 3) works and now the electrical team needs to work out how to scale up the system using a 36V power supply.

The electrical team will design 3D harnesses (Figure 4) for the assembly via SolidWorks Electrical. This will be accessed through desktop.sjsu.edu which gives access to ME lab computers. Electrical schematics will show where sensors will go.
