Week 4

Jan 30 2021:

Inverted belt direction on the intake elevator CAD model. This was completed by using a chain to sprocket output that leads to a pair of gears that mesh to reverse the direction of the input shaft. The shaft assemblies were also modified to make the shafts fit the intake tower better. The assemblies still need spacers to be added before they are finalized. The next order of business is to couple the bottom belting to the the back vertical belt to make them run together off of the single motor output.

The manufacturing team was training on the CNC mill. The speeds and feeds needed to be refined for the 4 flute vs 2 flute end mills. The programming inputs needed to match the machines gearing output. This initially didn't match and caused vibrations throughout the machine. The team also reviewed lathe operations and safety standards.

Our programming team was working remotely on the code. Some of the team members will continue to work remotely for the next few weeks.

The game design team reviewed previous FRC games and compared them to their current design. The team concluded they needed to simplify game play to allow audiences to follow easier. They also noted they needed the challenge to account for rookie and veteran team capabilities. This caused the team to reconsider some elements of the game and potentially different scenarios to implement existing elements.

Feb 1 2021:

The team developed an excel sheet that will help us monitor the progress of the 3D models and if their 2D part drawings are completed. The sheet will also host a To Do List for each sub assembly team to reference. When 2D part drawings are completed then they will be sent over to the Machinist Tasks tab. A machinist will be assigned to the task, and progress will be updated until completed.

The sheet will also allow us to keep track of which commercial parts we will be using for this years design. We can review our inventory, and begin to develop our shopping cart for parts that we will still need.

The programming team continued to work remotely. Team members downloaded Labview to their home computers . They downloaded their latest version of the code by connecting to the controls laptop via zoom and sending themselves an email with the zip file of the code. They unpacked the code, and needed to troubleshoot / reconnect sub VI's that were broken in the process. Since they are working from home they also needed to re-download the specialty libraries such as the CTRE and REV VI's.

Once they completed getting set up they worked on coding the intake system for the robot. This included calling out sensors and locating a place for them on the robot. The team also looked off of old models and finding out how to control each individual ball.

The CAD team refined the extended intake side plates, continued making drawings & fine tuned the base.

Game design finished side barrier gates in their CAD model.

The machining team worked on manufacturing bearing block plates.


Feb 2 2021:

The CAD team worked on finalizing more drawings for each assembly. They worked to completed assembly and part details as sub teams. Each sub team is lead by a mentor that works with the students for quality assurance of drawing standards.

The manufacturing team worked on creating bearing blocks made out of aluminum. They referenced the ABS 3D printed version from last year to check their parts for accuracy. They choose to make it out of aluminum because they wanted to be able to tap holes into the material.

The game design team installed gates to the field CAD model. The game pieces were also modified for aesthetic purposes.

Feb 4 2021:

The programming team simplified their tele operated code, and began setting up their autonomous codes.

The CAD team created their design binders and printed a second copy for the machine team to use. Team members began to prep our quality assurance techniques by setting up machining team folders, and containers for subassemblies to be placed into. Some of the design team members started manufacturing some of the simple mounting brackets for the shooter. These brackets have a large tolerance so they can be made using hand tools, bandsaw, & drill press.

Toward the later part of the evening design students were given a walk through of how to use a manual mill in our school machine shop. Unfortunately due to the lack of familiarity with the machine shop our process time took significantly longer because our students needed to aimlessly search the area for tools, equipment, and materials that were needed to complete the parts. This was a necessary learning curve, and will not likely be as difficult in the future due to this evenings learning experience.

The machining team worked on creating a MasterCAM file for the bearing blocks. The team also used the internet connection that was installed earlier this year to the machine controller to send MasterCAM files to the machine through Path Pilot. We simply needed to set up an account online, and login to our machine to access the files. Our freshman team members worked on CAD and helped organize drill bits and end mills from a sponsor donation.

The game design team worked on flushing out the game manual to prepare for their submission later this weekend.
