Spring 2016 Updates

Since the last semester, the Fail-Safe team has made a significant amount of progress. During the time from the last post, the team has taken on the role of motor for propulsion. Other changes that has occurred involved the team working to together to reduce the cost of the bogie.

Cassie has taken lead in the fabrication due to her having the best schedule to work with the tech shop. She has already fabricated most of the parts. The cost to waterjet the plates ourselves was the same cost as having another party help except doing it ourselves would allow us to work on our own schedule. However, we do have an issue do the the limitation of machine time we have access to.

Christopher has taken lead in finding the right motor for the bogie and will also take lead in controls. The motor he found most appropriate for our parameters is the Crystalyte SAW400-series motor with the 4825 Controller, as shown in Figure 2.

Lastly the rest of the team is working on helping with finalizing designs to mount the motor and he appropriate wheels for the bogie. The design is for the bogie is slowly being modified as other groups are making modifications which require us to change our design due to the fact the the bogie will house all of the other teams projects. We are also helping Alex with working on the guideway. The team is working well with the intention to finish by Maker's Fair.
