Update
It is Kick-Off time, we are tuned in watching the stream and getting ready for the next 3 days. Also, our stream is up at: Twitch

Update
The game has been revealed! We are now unlocking the Game Manual and giving it a good read.

[Ga3ta]

Update
We have started digging into the points of the game, reading which interactions are allowed and which aren’t in order to device a strategy to follow to design our robot.

[merfin04]

Update
The dust is starting to clear and now we are evaluating different prospects for our robot. We are only discussing the “whats”, and after consideration, we will start assessing the “hows”.

[Ga3ta]

Update
We played around in the simulator and discovered that algae is quite tricky to remove from the reef. We also experimented with our own algae and realized that it was almost as bouncy as the 2019 cargo. We are now crunching the numbers on scoring cycles to back up our strategies and afterwards, decide to follow the one that results in the best scores.

[Ga3ta]

Update
After the lunch break, we decided on a strategy. Based on points and actions, we decided that our robot would focus on scoring corals on the first and second level of the reef, since they are below the starting configuration limit height. We also decided that we wanted to be able to remove algae from the reef and be able to manipulate them to deposit them in the processor. Our priorities for prototyping were set as follows:

1. Deposit corals on the first and second level
2. Manipulate algae to deposit them in the processor
3. Be able to hang from a shallow cage
4. Remove algae from the reef

We have bought materials to build a simplified version of the field elements and will work in parallel to build said elements, as well as our prototypes for the mechanisms.

[Ga3ta]

Update
We decided to start with the coral placing mechanism. Our idea is to prototype a giant pivot with a gripper consisting of compliant wheels at the end in order to vertically place corals at level 2.

After deciding on the idea, we did a quick Crayola CAD in OnShape to start getting measurements.

In the meantime, we started manufacturing a reef-like structure with PVC in order to test out the mechanism.

Update:
Right now a beta YOLO (You Only Look Once) model is being trained for Algae detection using computer vision

We’ll keep you posted about how it works and keep labeling more pictures for a better performance.

Update
And this is a big one. After several hours of design and manufacturing, we have our first two prototypes built and almost ready to test out. The first one is a coral intake, that has a hopper like structure that ensures that corals enter vertically. We tested it out and found out that after taking in the coral, the vibrations of the mechanism moved it to either side of the mechanism, misaligning it, which is not the ideal, since we want it to be perfectly vertical.

The second prototype of the night is an algae grabbing mechanism, which is similar to many 2019 cargo intakes. It consists of 4 compliant wheels that form a “C” shape that compresses the algae. Our prototype is also adjustable in the distance between both spinners and the distance from the back of the mechanism to the axis of rotation of the spinners. We plan to adjust them in order to get the best compression factor that allows us to secure the algae without damaging it and it falling over. Our initial tests reveal that using compliant wheels with a higher robustness allow it to store it better, because compliant wheels that are more malleable store potential energy at the moment it intakes an algae, and when the motors stop spinning, this energy is released and throw out the algae. More rigid wheels store less energy and allow the algae intake to better hold them. The compression factor was also key, we found out that compressing the algae 2 inches was too much stress for the ball, so the next tests will evaluate a smaller compression. The distance that the algae intake covers was also important. Our initial design contemplated only grabbing the algae from the center back, so 8 inches of algae are contained within it, but our prototyping revealed that more distance is required.

Our programming team also managed to figure out how the new control system and radio work, enabling the M14 drive train. Our problem was that the new control system and roboRIO image require us to have the 2025 version of the Phoenix Tuner X, which as of now, we couldn’t obtain from the Microsoft Store. We are still waiting on the offline installer for the latest version of the Phoenix Tuner X.

And in the meanwhile, our first field elements are almost done! The reef’s first and second level were left drying and will be available for tomorrow’s extensive testing.

Update
Last update of today. Our last prototype of today was this pincher. It excels at grabbing the corals horizontally and has a strong and sturdy grip. We hope to attach it to a more robust structure tomorrow to be able to corroborate whether it can pinch an algae or not.

I can’t tell from the picture, how far apart are those wheels?

[Ga3ta]

Update
So last night before going to get some sleep, we decided on an intake. The hopper/vertical-grabbing intake was discarded because it was just too complex trying to line up the coral in the vertical position without it flying over to one of the sides. On the other hand, the C-shaped horizontal intake is simple enough, and with a wrist on its base, we could use it to place corals both vertically and horizontally. While the original idea was to avoid using a wrist since it means spending resources on an additional motor and encoder to have precise rotations, the v-shaped intake just needs to be further analyzed and prototyped, and for the exercise of Ri3D we just do not have the time and have prioritized moving with the wrist c-shaped intake.

We will stick to our decision and mount said intake in a pivot structure which will be the base of our robot. We plan to have an arm that swings around to grab corals from the coral station and then place them both on the first and second level of the reef. This was planned in order to not have a complex elevator mechanism that would be needed for the third and fourth level of the reef.

We leave here attached the Fusion CAD models for both of our intake candidates.
