Days 42-43: Scrimmage Preparations & Robot Finishing

Scrimmage Preparations

After a very stressful period of the field shipment being delayed, it finally arrived at about 1:30PM on Saturday, Day 43.  We immediately started assembly and had it just about done before dinner time.

Robot Finishing

Both us and our sister team, 1868 have been finishing up our robots.  Today, 254 ran its first tube test and scored several tubes on all rack locations after loading tubes from the ground and the human player.  The scoring mechanism works great but the elevator and arm need some additional programming to increase controllability.

Day 41: Chairman’s Submitted and All Parts Back

Chairman’s

Today, our Chairman’s Submission was published.  You can read it here.  The Chairman’s Award is FIRST‘s highest honor, celebrating excellence as a whole team in addition to success on the field.

Assembly

Today, we got the last batch of parts back from the powder coater.  At this point, all parts have returned from their respective sponsors.  Assembly has started and will continue tomorrow.

Scrimmage Preparations

Unfortunately, our practice field has gotten stuck in Chicago and got slightly delayed.  Due to the generosity of NASA, our title sponsor, the field was expedited and will be here between 5AM and 7AM on Saturday.  We will need to work extremely hard to get everything ready for the scrimmage.

Day 40: Elevator

Today, the elevator worked for the first time.  It is extremely fast.  We are taking the final batch of parts to the powdercoating shop in the morning.

Day 38: Machining, Wiring & Pneumatics

Machining

Today, the machining team worked on the elevator second stage top and bottom caps.  The bottom caps are complete and the top caps are in progress.

Furthermore, on the lathe, we worked on various spacers and shafts.

Wiring, Pneumatics & Programming

Today, we finished (except for sensors) wiring the bases on both robots.  Our second cRio arrived and we flashed it, allowing us to run both robots simultaneously.  We plumbed the pneumatics on the base of both robots and ran a pneumatics test on the practice robot.  After fixing several leaks, the system is good to go.

Control Boards

Today, we got the control board back from the CNC routing sponsor.  The next step is assembly.

Day 35: Gearboxes, Field Trips, Bumpers and More

Today at the lab, we got our parts back from the anodize shop which allowed us to finally start assembling gearboxes.  Everything looks great and this task should be finished in the next few days.

On a separate note, we had several FIRST Lego League students who came to tour the lab today.

Also today, the manufacturing and assembly teams were hard at work finishing the bumper frames. We will wrap fabric on the bumper frames tomorrow to hopefully finish the bumpers.

The minibot team has just about completed the CAD model of the final minibot. The design is now due for review and manufacturing in the next few days.

Day 34: Manufacturing, Programming & Bumper Assembly

Manufacturing

Today, the manufacturing department was hard at work finishing most of the parts for the bumpers and working on the shifter dogs and minibot deployment rail end caps.  We hope to have every machined part done by Monday.

Programming

The programming team has been busy over the last few weeks perfecting teleoperated drive code.  Using a mix of linear, exponential and logarithmic functions, they have refined Onslaught’s teleoperated control.

Bumpers

The bumpers are coming together.  Today, we put all the steel nut plates onto the bumpers and cut pool noodles to length.  They should be completed tomorrow.

Day 31: Wiring & Manufacturing

Wiring

Today, we continued wiring the robots.  The competition robot is coming along nicely and is nearing completion.  It should be completed in the next few days as soon as our remaining orders come in.

Manufacturing

Today, the CNC team was lightening gears and cutting dog teeth into the shifter gears.  On the lathe, several team members worked tag-team all day to keep the machine running constantly while making spacers and shafts.

On the mill, we were working to turn out the wood backings for the bumpers which should be completed tomorrow so that bumper assembly can proceed.  We also received the bumper fabric back from embroidery today.

Days 29 & 30: Wiring Weekend

First of all, I apologize for not putting a post up last night.  I got home late and forgot to grab pictures off the camera before leaving and thought that a blog post without pictures might be a bit boring.

Anyway, today was our big weekend of wiring the robot.  After countless man-hours of work put in by many dedicated team members, the practice robot wiring is complete and the competition robot is half-way complete.  We are still waiting on some components to mount on the comp robot electronics board before we can finish wiring.

On Sunday, we were able to successfully test all of the speed controllers and relays on the practice robot.

Machining is coming along well too.  The gears for the gearboxes are almost done being lightened and we are sending out many parts to anodize in the morning.

The programming and controls team has been hard at work.  We have put together joysticks for the control board and have worked to put provisions into the code for the control board.

Day 28: We Have Robots!

Today, we got parts back from both the anodize and powder coat shops and began assembling and wiring the frames.  Our sponsors are the best, allowing us to get frames powder coated in 1.5 days so that we can catch up on our schedule.
