Week 4

Jan 25 2025:

We've been refining our CAD model to include the intake, extension, and pivot assembly. The meshing points between all these assemblies still require lots of work but we are trying to expedite our progress as our deadlines for CAD is approaching. The need for extended time by the CAD team is increasing and our manufacturing team remains ready to create final robot parts.

Intake prototypes were refined to include a horizontal and vertical rollers. We have reached frustration due to our lack of prototype robustness. We have lost time due to trying to make things work for quick solutions, but that has been. 

Jan 27 2025:

We mocked up a climb and tested to see if our gearbox would handle picking up the robot. The gearbox only had one motor so we expect better results when we can attach additional motors, but we saw a reasonable amount of movement from our single motor prototype.  

We connected our horizontal prototype to the base of kitbot to get a consistent height for our intake testing. We modified our cat tongue grip tape pattern to bias the game piece to one side. We see this effect in the video below but it wasn't as repeatable as we would have liked. The limitations are assumed to come from the lack of structure in the wood and some of the hardware. 

We will look to modify the pattern and the amount of compression for future tests to see if that will improve our results. In addition to adding silicone to the outer roller for "touch it, own it" effect we are looking for.

We continue to refine our prototype of intaking in a funnel shape to work on orienting the coral. We are currently not able to get the game piece in if its against the wall of the reef. With some driver training we could easily push the coral to the side and acquire it. 

Jan 28 2025:

We made 3D printed versions of our bearing blocks for the telescoping tube to test our tolerancing for bearings. We cut some 6in tubes to test our mounting on a small scale and prove our scaled up model. 

Our intake team worked on tuning the inline spacing for coral testing the compression effect at the loading station and placing on the reef. The base material below the surface of the coral allowed the game piece to enter and exit the mechanism quickly.

We found that the large wheel made a big difference in centering the wheel. The key feature we found was the larger diameter wheel wouldn't jam on the face of the coral. A critical finding we are looking to improve on immediately to optimize the window of our intake.

We added a second motor to our climb prototype and we saw an improvement in our lift. The next point of improvement will be increasing the chain tension. 

We will look to improve our attachment point to be wider to two of the four cylinders rather than the single one. Next we will iterate how to improve alignment methods

Jan 30 2025:

The intake team worked on our funneling system for coral by using some eagle belting instead of wheels. This is to see how well the belting compares to the wheels.

We updated our part tracker in our manufacturing area. We remounted the screen to make it easier for team members to access the screen and input data. 

Students created a form to attempt track who is working on the mill and lathe. They would like to have more information about the tooling used in an attempt to set up a preventative maintenance schedule. 

The programming team worked on using new tools, setting up vision systems and tuning systems to prepare for auton paths.

CAD models continued to be refined.


We implemented a Everybot climb barb as a latch mechanism to the cage. 

We added a "Foot" to brace against the bottom. It prevents us from sliding down the cage as we rotate the arm for the lift.
