Day 35. Feb 12, 2016

Today, the anodized parts for the final competition robot arrived. We will even use anodized rivets!

All of the drive gearboxes are complete, for the final practice and competition robots.

We have mounted the shooter, intake, and intake minicims.

Today, we began recording our reveal video as well!

Day 34. Feb 11, 2016

Today, we assembled several gearboxes.

BAG motor versaplanetary gearboxes for the measuring tape:

We are slowly disassembling the V1 robot. Some electronics are still in working order and are useful for programming.

Protobot

We are hard at work assembling the V2 robot. The drivetrain and intake are on their way to completion.

Day 33. Feb 10, 2016

Today, we assembled the final practice robot’s shooter.

We also began to assemble the drivetrain.

We machined several aluminum tube components to be used throughout the robot as well.

Day 32. Feb 9, 2016

Today, we bent all pieces of metal for both our practice and competition robots. For the drive plates, we borrowed Team Spectrum’s (#3847) brake.

We also worked on wiring the Talon motor controllers and the versaplanetary encoders for the shooter.

We began programming PID control for the shooter today as well.

One of our mentors built a hanging bar for us.

The CAD for the final robot is finished and almost completely finalized!

Day 31. Feb 8, 2016

Today’s main achievement was plasma cutting new copies of our robot’s sheet metal components.
We also cut new tube components for the robot and drilled the holes they required.

We also experimented with the CNC router, attempting to use it to drill holes in aluminum tube, and cut lexan.

We cut and bent a mount for the battery out of lexan, and planned how to fit and organize the electronic components as well.

Day 29. Feb 6, 2016

Saturday, in plan this is the big CAD day to finish everything up but at first we decided to get all of the parts tested to see what was wrong and what we had to change on the robot. Today we had a lot of members show up and a lot got done.

Here is the list for CAD:

  1. Intake needs to move back as we don’t have a good handoff between the intake and the shooter.
  2. Intake also needs to be changed to fit between the 8 inch bumper rule from each corner.
  3. The shooter needs to be higher angle (a lot of testing was done today on the angle/trajectory of the shot and how it reacts to different angle/speed)
  4. Electronics are cramped so we need a good place for them in CAD and on real robot.
  5. Gearboxes could be moved down and we have a lot of space on outside of the wheels so we can shorten the robot.
  6. Bumpers need to be added as well as the supports.

Most of this was done but some of it will be done at home by some of the members. The parts will be cut after school Monday so there is time to check everything and get things finalized before then.

A lot of work was also done on the scaler. The idea we have been dilligently working on for the last 3-4 days had to be scrapped as it was not very well executed, did work well at all actually.

For the hanger the current prototype is a tape measure that will deposit a hook onto the bar which will winch us up as high as we need to go.

This will be easier as we have tested this and the big tape measure does not bend, takes up less space and will be very quick to go up to the climber bar. This should give us a lot more space to work with as well as this will be a much more compact system.

Our scouting group also created a sample template for scouting which will be iterated on to create the final scout sheet we will use at our regionals.

It is now week 5! Only 2 weeks left of build season and a lot to do!

Day 28. Feb 5, 2016

Today we did a lot of prototyping and figuring out what everything will look like and what it will do.

Here are the parts we worked on:

We got the shooter and intake on the current drive train and were able to test it a little:

Here is the shooter test:

Here is the drive going over different obstacles:

So far everything is going to plan.

We also continued to work on the hanging mechanism.

Day 27. Feb 4, 2016

Not a lot was done today as we had a decently bad turnout but we put the intake on the robot with just 2 2x1s of aluminum. This allowed us to see what the final dimensions and intake would look/act like.

We also planned for the following day expecting a lot of people as it is getting to crunch time.

The basic schedule for the next couple of meetings:

  1. Friday – final intake, shooter and drivetrain all together working
  2. Saturday – hanger prototypes done and tested, CAD finalized for final cutting of the practice and competition robot
  3.  Monday – plasma cut the final robot (2 copies)
  4. Monday after school – clean up plasma cut parts (both copies)
  5. Monday night – bend both copies of the robot
  6. Tuesday AM – give one copy to anodizing
  7. Tuesday start building the practice robot (non-anodized version)

Tomorrow we will finish building everything and make a plan for what to change in the final CAD iteration and the final robot version.

Day 26. Feb 3, 2016

We worked on assembling parts today. We assembled the gearbox, intake, and shooter.

Assembled intake Version 1:

2-4 (4)

Assembled shooter Version 2:

2-4 (3)  2-4 (2)

Assembled gearboxes for drivetrain:

2-4 (1)

We employed some interesting methods for machining, including using our drill-press as a manual lathe for plastic.

We also broached plastic parts and steel bevel gears.

2-4 (6)  2-4 (5)

Day 25. Feb 2, 2016

Today, we bent the second version of the shooter, and the first version of the intake. The intake is a little flimsy so we will test it and will probably have to make it a little beefier at least where the bearings are.

We also fully put the 8-wheel drive base together and tested it. Looks good so far! We are going to start finalizing the drive and shooter as soon as we get the shooter on this drive.

 

We continued thinking about lifting at the end of the match.

Besides this prototype we are working on a 2 bar (kind of like 4 bar) arm that we will put together tomorrow and test and put a picture on here.

Unfortunately the liquid nails did not secure the steel to the wood successfully. We used bolts instead.

Adam also ate a peanut-butter and jelly sandwich for the first time today.
