We used a manual mill and manual lathe to build most of the parts of our robot, as well as a water-jetting sponsor for important yet obscure parts (transmission plates/brackets, funny shaped gears). Lots and lots of iterative CAD modeling and packaging went into the design of our climbing mechanism, but that is a process that is not easy to document!

Team 1816 The Green Machine in Curie has cool stuff for you to see!

Our robot this year utilizes, and won the rockwell automation inovation in control award for:
-3D printed "augers" (helixes) That hold and index frisbees when in a triangular pattern.
-Ornate water jetted baseplate for the frame of the shooter.
-Fully automated vision control system with point and shoot accuracy.
-Fully CAD-ed robot
-3D models with moving parts to show off the robot.

Come to our pit and any of our team members can give you more detailed information, or ask for Kevin. You can also look at our website www.edinarobotics.com for a picture of the robot.

Re: FIRST Behind the Design Book 3.0 (plan)
 

We've been waiting years for this book, thanks!


I wonder if you could do a small bit (perhaps one robot) showing how a robot can be built without any modern manufacturing techniques? Just to put it all in perspective. I doubt we have sufficient documentation of our low tech build, but someone might.....

Re: FIRST Behind the Design Book 3.0 (plan)
 

Team 696 is interested.

Re: FIRST Behind the Design Book 3.0 (plan)
 

This would be awesome. Kids these days (:rolleyes:) put way too much emphasis on having computers doing all the work instead of using their brains. Our school has a CNC (only, doesn't have handles!) mill, CNC routing table, and 3D printer and at the insistence of a few of us mentors we are just getting a manual mill.

Looking forward to reading it!

Re: FIRST Behind the Design Book 3.0 (plan)
 

I'll buy at least one!

But it really should include team 1899. Using laser cutter, common "door skin" plywood, a bit of epoxy and some brilliant CAD, they have created the lightest, stiffest, cheapest robot frame at worlds.

Okay... technically I haven't seen all the robot chassis going to worlds, let alone conducted stress tests and detailed financial analysis of them, but I'm more than confident that they deserve to be "in the book".

And, for the record... this isn't one of those million dollar lasers that cuts steel... this is a relatively affordable wood/plastic type of machine. I encourage you to try standing on one of their backup chassis!

222 would be happy to have you come visit our pit in Galileo!

Since I am a sponsor and mentor of 222 I will be in attendance at the championship.

We have a wide assortment of 3D printed parts on our robot this year. Everything from sprocket spacers to frisbee launching device to bearing blocks.

Here is our original frisbee launching device in the lower area of the picture. At the end of the build process we figured that it was critical to redesign the "pushing" device to allow for frisbee stacking. We were quickly able to 3D print a new design that was shorter and also wedge shaped so that the forward motion pushed the frisbee forward into the launching tire. The backward motion is where the wedge shape came into play by allowing the wedge to push the stack of frisbees up and over the pusher device to fire the rest of the frisbee stack.

If you do happen to be interested in speaking to me and I'm not in the pits when you stop by just ask for a team member to text/call me so we can find each other.

Re: FIRST Behind the Design Book 3.0 (plan)
 

The students of FRC2168 would be happy to discuss our robots design and our manufacturing style with you. We'll be on Curie this year (the team's first year ever making it to Championships).

Here's a picture of the rev 2 robot this year. The team completed a complete redesign of our superstructure between regionals.

No matter what I will likely do the same thing I did last year and post up the design break down of both machines I mentored this year.

Thank you again for getting these books up and going again. They are an awesome resource for the community.

Vince,

We have a nice control system to control the angle of our shooter. It is very precise. It won a control award at Boilermaker. Stop by FRC 1741 in Newton.

I am looking forward to meeting you.

We use the DI/O ports of the sidecar, one each for red, green, and blue, and a custom circuit for the LEDs.

Re: FIRST Behind the Design Book 3.0 (plan)
 

125 is interested. We are very proud of our design, and our pit crew would be happy to explain the systems and how we designed and manufactured them. Please come find us on Galileo.

Re: FIRST Behind the Design Book 3.0 (plan)
 

I'm excited to see the positive responses about the next book, and I look forward to meeting you all at the Championship. Keep those posts coming!

Re: FIRST Behind the Design Book 3.0 (plan)
 

You're more then welcome to stop by 1902's pit and talk with some of our students. We'll be in Archimedes (just look for the pig face beacon on the wall).

Our 'Users Manual' is here if you want to get an overview of our design and build process.

Thanks for doing another edition, I look forward to reading it.

Re: FIRST Behind the Design Book 3.0 (plan)
 

Hi Vince and Stephanie! Great news that a new book is in the works! If you have time, please feel free to stop by Team 78's pit. We will be in Archimedes. There are several robot parts that were 3-D printed and some parts that were cut out with a waterjet/CNC mill. The kids would love to show our hard work! See you in St. Louis.
