Prototyping 1/11/2022

After kickoff, we jumped right into prototyping! We researched designs used by teams in years past to get a general idea of what we wanted our storage system to look like. After we found some good references, we tested out two types of systems; pulley and wheel.

Prototyping 1/12/2022

We started by using belts to move the cargo, but quickly found out that the belts would not stay seated in their wheels. Then, we started using smaller black rubber wheels to move the cargo, which worked better. We ended by trying to connect the two rows of black wheels, and were close to getting it working.

Prototyping 1/13/21

We finished the fist prototype design and tested it to see how well it worked. We found that we needed to do some small tweaks like make the back board a little closer and move around the height of the wheels. We tested the capability of it by hand feeding two balls and out taking them as needed.

Prototyping 1/15/2022

Today, our storage team worked extremely closely with intake in order to get the intake and storage to work as one mechanism. We mounted it 11" away from the bumper, and then we added Lexan in a curve following the trajectory in order to make the transition smoother. We attached the top two axles to belts and pulleys in order to make them move simultaneously and then tested intaking the balls up the storage. Our goal when intaking was to try to find a point that the ball jammed, in order to find flaws in our design. We discovered that the ball got stuck between the second intake axle and the first storage axle when we out-took the ball, so we put Lexan over that gap to solve the issue.

Prototyping 1/16/2022

Since our storage and intake mechanisms were fully functional together, we decided that we should start planning for our actual storage system while shooter was still prototyping. First, we had to consider how our storage mechanism would be oriented in order to allow for the intake to retract into the starting frame perimeter. We figured that the simplest method would be to pivot the storage back at an angle into the robot and have the storage in that fixed position to allow for the intake to have enough room to fold back in. Our only concern with this method was that the storage might interfere with the hang in this orientation. From there, the cargo team and the hang team sent one representative to make a rough robot real-estate to give us an idea on the amount of room we had. While we were waiting, the rest of cargo began to consider other options, including spring loading the second intake axle so that it becomes flush with the first axle when inside the robot and folding the intake up, with the second axle being the pivot point. After dinner we verified dimensions and used those dimensions to create a shopping list so that we can get started on designing our storage mechanism.

CAD 1/19/2022

After a team integration to get everyone on the same page, cargo joined as a group to assemble our prototypes in CAD in order to figure out how to retract intake and what angle storage/shooter will be in order to maximize space efficiency. We each made separate assemblies for each mechanism and then placed them in a drive base assembly. Once the intake, storage, and shooter were all in one assembly, we were able to properly constrain and align the mechanisms to what we believe is the most beneficial positions. By placing the storage 48.82 degrees from the top of the drive base and by setting the intake pivot point to the top of the storage, we were able to retract the intake into the frame perimeter. Tomorrow, we will try to assemble this complete cargo pathway using the tools in our shop and see if all of our dimensions are still accurate.

CAD Prototyping 1/20/22

today we started putting the robot together based on the cad model we made. we made the storage to spec as it is in the cad model and are planning to add the intake and shooter soon. we put the storage on a base mock up on a 26 by 28 frame of our robot.

CAD 1/22/22

CAD was redesigned to more accurately reflect what the mechanism will likely become. An adjustable bracket was modeled after one of our designs from 2017 and the top 2 axles of the storage conveyor were placed on this bracket for easy and quick adjustments to the mechanism. A new mounting bracket was started to better integrate the bottom axle of the storage mechanism as the pivot point and back axle of the intake.

CAD 1/23/2022

Today, we made a mounting bracket for the second and third storage axle motor. We also examined the belts that we would need for the axles. Then, we began to look into where we will mount the intake pistons on the storage. We made a CAD model of the intake, storage, and shooter in one assembly to see how it all fits together and to determine where we will place the sensors.
