Integrated System Build & Test
Table of Contents
Team Vision for Integrated System Build & Test PhaseAccomplishments:
- Solenoids rotate the boat switchers without issue - confirmed the output force & stroke length is sufficient
- Machined microcontroller (uC) rail, 2 solenoid rails
- uCs mounted to their rail with standoffs
- Developed code to coordinate solenoid and motor movement
- Identified reset issue root cause & improved code - previously we were tripping over-current limit on startup due to immediate movement requests. Adding startup buffers helped.
- Deliver Appropriate Signals: The controls team is working through this to integrate the computer interface and set up independent PWM for all motors.
- Generate Path: This has not been started yet, but once the code has been set up it should be possible for mechanical engineers to do this.
- Load User Instructions: in progress.
- Deliver Appropriate Signals: There should be minimal rework since the only main difference from the horn gear movement is the clock rate. This will be addressed after horn gear movement is further along.
- Load Movement Rate: This may be hard-coded for prototype
- Deliver Power: still waiting on connectors from digikey order, using Brandon's power supply in the meantime
- Tension Fiber: We originally hoped to simplify design by removing the spring and slider portion of the tensioner, however there is too much slack that needs to be taken up so it will be added back in.
- Hold Bobbins: The boat and track method has been kept constant for most of the project so far. Minor updates are being made for tolerancing. Experimentation is being done with the flange above the boat to try to resolve problem #10 (see below)
- At this time, additional safety and user separation methods are lower priority. The motors are low speed and low torque so there is minimal risk of injury.
Surprise! The Novel Coronavirus, CoVid-19 led to a nation-wide shutdown, and campus was closed the week after the end of our spring break extension week. After this point, we were not able to access any of our hardware and our focus shifted to documentation.
Test Results Summary
Summarize test results and assess effectiveness of test plans to unambiguously demonstrate satisfaction of the engineering requirements
- Quantitatively summarize the capabilities, performance, throughput, and robustness of your subsystems as demonstrated by execution of the test plan. Document your testing with photos or videos in addition to test data.
- Evaluate how well the test plan was able to confirm satisfaction of subsystem and system requirements
- Include snapshot of testing completed to date, and include link to live requirements and testing document

Plans for next phase
- As a team, where do you want to be in three weeks at your next demo with your customer (if you haven't already done this)?
- As an individual on the team, what are you doing to help your team achieve these goals? (Use the individual 3-week plan template for this)
