Team Vision for System Level Demo with Customer

This phase our team wanted to have the system put together and controlled at least locally by the micro-controller. We wanted to make sure that all the sensors worked as expected in the system and actually try and collect data from a shock absorber. A stretch goal was to actually have FSAE team members try and use the dyno as well as members from the Baja and HotWheelz testing it.

The team got a lot of the dyno built. The dynamic portion of the system was completed to the point that the unit would exercise a shock absorber. The motor control was worked out and the micro-controller can start, stop, and modify the speed of the motor.

Due to manufacturing problems, the static crosspiece that holds the force sensor, shock body, linear potentiometer and temperature sensor was unable to be assembled. Also, the safety enclosure was made too wide and couldn't be fitted in time for this review. Because of this, we weren't able to actually take measurements of a shock and test the full system.

Test Results Summary

The full system could not be tested, so there are currently no quantifiable results from testing. We have been able to verify that the micro-controller can operate the motor but we can't tell if it can keep a constant linear velocity under load or that it can measure the temperature, linear speed, and force at the proper times and report them back to the user interface software.

Plans for next phase

The team hopes to have a fully functional unit that has been tested and documented for the final review. We still have the crosspiece to manufacture and test, the sensors need to be mounted and wired to the controller board, and the remainder of the safety circuit needs to be mounted and wired.
