Days 36 & 37: Driving Robots

After countless hours of gearbox building, wiring and troubleshooting, the practice robot is finally driving.  Furthermore, we have assembled one set of  bumpers.

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 33: Manufacturing

Today, we continued to work on manufacturing many of the primary parts for the robot.  The dog gears were started and are coming along great.  Furthermore, the bumper corner pieces are completed leaving the bumper pins as the only pieces remaining to be able to finish the bumpers.

Day 32: Manufacturing

While we are waiting for parts to return from the andoize shop, we have been doing a ton of manufacturing.  Today, we finished lightening all of the robot’s gears and finished milling bumper wood.  Furthermore, we cut the steel bumper pin mount pieces and worked on shafts and spacers on the lathe.

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.

Day 27: Prototyping, Manufacturing & Design

Prototyping

Today, the prototyping group worked on their minibot design.  The minibot is coming together.  However, we have hit a setback in that one of our motors has burned out and we need a replacement.

Manufacturing

The manufacturing team was hard at work today machining a number of plates and lathes for the robot.

The robot frames were dropped off at the powder coat sponsor early this morning and should be completed tomorrow.

A team of students marked out the locations for the embroidered team numbers on the bumpers.  They will be embroidered beginning tomorrow.

Design

Today the design team worked on the design for the bumpers and the control board.  We are hoping to get the control boards cut on a CNC router but are looking for potential sponsors.

Day 26: It’s Beginning to Look like Robots

Manufacturing

Today, we received all of our parts back from the welding sponsors.  All of the welds look great and beautiful and we were able to begin assembling parts.  The frames are being brought to the powder coating sponsor early in the morning and will be powdercoated soon.

In other news, manufacturing and prototyping continued and we got a shipment of parts in today.  We hope to finish machining in the next week.
