Robowrangler Sheet Metal Giveaway Round 2
 

Hello All,
The Robowranglers have been doing a lot of organization as we move into our new shop. We are cleaning out and getting ready for FRC STEAMworks in 2017. Through this cleaning we've identified several spare parts and assemblies which we don't have a home for.

In the past, we've had a few other FRC teams ask for some of our extra sheet metal (we do our best to help out with these requests). In each of these cases, the teams would later comment on how much they learned about sheet metal fabrication techniques by analyzing the components and assemblies they received. We know it is helpful to review a CAD model, but there can be a benefit from holding a part in your hand and trying to bend it in different ways.

We're offering a several different Robowrangler assemblies to other teams for educational purposes. These are all spare components since we don't disassemble our competition robots after a season.

If you're interested in one of the items listed below, send us an email at robowranglers148@gmail.com with your request, and we'll do our best to accommodate. Items will be sent on a first come first serve bases. Please send a first and second request and we will do our best to send your #1 item.

If you have any questions about these components or this offer, shoot us an email!

Thanks,
Madison

1.Renegade 2016 Prototype Chassis 1
This was a prototype drive used in 2016 Stronghold to test the durability of #25 chain and 775 pro motors. This was also used to test our wheel configuration on the competition defenses.

2. Renegade 2016 Prototype Chassis 2
This was a prototype drive used in 2016 Stronghold to test the durability of #25 chain and 775 pro motor gearboxes. This was also used to test our wheel configuration on the competition defenses.

3. Batman Chassis 2015
This is a spare drivetrain chassis from our 2015 robot, Batman. It was shaped like a C so it could intake full stacks.

4. X-006 Chassis 2012 (x2)
X-006 was a prototype drivetrain before the 2013 season. This drivetrain tested butterfly modules.

5. Renegade 2016 Chassis
These are spare C channels from Renegade’s drivetrain. These show how wheel spacing works and certain sheet metal bends.

6. Renegade 2016 Intake Rev 2 (x3)
This was the second redesign of our 2016 intake. This sheet metal shows how to compactly fit a motor and gears in a tight area.

7. Renegade 2016 Intake Rev 4 (x3)
This was the fourth redesign of our 2016 intake. This intake was more efficient than the previous one. This intake shows sheet metal bends and has a better presentation than the previous Rev.

8. Vader Shooter 2014
This is a spare catapult used in the 2014 game.

9. Renegade 2016 Catapult Rev 1 (x3)
This was the first design for our catapult. The sheet metal design efficiently shows lightning patterns.

10. Renegade 2016 Catapult Rev 2
This was the second design of our catapult. It worked better because it had a lower bend angle.

11. Renegade 2016 Structure (x2)
These sheet metal pieces were made to connect the hangar and catapult to the belly pan/drive base.

12. Renegade 2016 Drum
This was our hangar drum. This design shows how the same sheet metal part can be used multiple times to create a solid piece.

13. Batman 2015 Stackers Rev 1
These stackers were used in the 2015 game during auton. They were mounted off of Batman's rails.

14. Batman 2015 Stackers Rev 2
These stackers were used in the 2015 game during auton. They were mounted off of Batman's rails.

15. Batman 2015 Stackers Rev 1 with flaps
These stackers were used in the 2015 game during auton. They were mounted off of Batman's rails.

16. Batman 2015 Arms
The purpose of these arms were primarily for structure. They connected to the 4 Bar in the back and stackers in the front.

17. Robin 2015 Back Arm
This piece was for structure at the top of Robin. The sheet metal is a C shape and connects from one side of Robin to the other, while resting on the human player station.

18. Robin Base + Robin Trap Door 2015
These were the components of the bottom of Robin. The base was the very bottom that sat on the ground and totes were stacked on. The trap door kept the totes aligned inside Robin and was shut until Batman drove into Robin to intake a full stack. These parts show how sheet metal can be designed on a larger scale.

Re: Robowrangler Sheet Metal Giveaway Round 2
 

This leads to a 404, FYI.

Re: Robowrangler Sheet Metal Giveaway Round 2
 

Thanks. Should be fixed now!

Re: Robowrangler Sheet Metal Giveaway Round 2
 

What an awesome resource for teams, thank you for doing this again!

Re: Robowrangler Sheet Metal Giveaway Round 2
 

One of the coolest things any team does. Thank you.

Re: Robowrangler Sheet Metal Giveaway Round 2
 

Thank you SO much for offering this opportunity. I sent an email about 30 minutes after it got posted (I was at a slight disadvantage with it being posted at 7am Pacific Time :p), I hope that was quick enough! Do you know about when we'll know if we got anything?

Re: Robowrangler Sheet Metal Giveaway Round 2
 

This is an amazing opportunity for teams of all levels. Thank you Team 148 for providing not only your digital design models to teams, but working to help improve the knowledge of others!

Re: Robowrangler Sheet Metal Giveaway Round 2
 

Team 148 very generously gave our team a spare raptor head from their 2011 season a few years back that we keep in our shop with our old robots and other miscellaneous mechanisms we have acquired. I have to say that being able to look closely at the design and how all the pieces fit together was a great resource for me when I started learning how CAD sheet metal parts. This is truly a great resource, and I think it's awesome that team 148 is doing this!

Re: Robowrangler Sheet Metal Giveaway Round 2
 

I will forever be jealous of the level of resources and expertise it requires to create the robots you guys make. 2 prototype chassis' in a season? Holy cow. I can't imagine being able to do that.

Keep inspiring us 148.

Re: Robowrangler Sheet Metal Giveaway Round 2
 

Thanks for offering these parts up to teams, 558 would like to get our hands on some sheetmetal parts for sure. I noticed you say this was used for testing the 775pro motors in the drivetrain. Would 148 share what they learned? Thanks.

Re: Robowrangler Sheet Metal Giveaway Round 2
 

Our testing showed that the 775pro motors would function fine in the drivetrain. We had no issues with the motors. While we identified several specific failure points which would be fixed in the final design, these individual lessons contributed to the larger lesson of: "Overkill is totally appropriate for this game." That philosophy drove MANY decisions on the final robot including the decision to go with CIM motors in the drive, the addition of bearing plate doublers on the final drivetrain, the increase of material thickness in most locations, and more. Renegade is one of our toughest robots, in part because this chassis taught us we needed to build it that way.

We are overwhelmed with the number of responses we've received. We are going through all of the emails and will get back to everyone by tomorrow!

Re: Robowrangler Sheet Metal Giveaway Round 2
 

Madison... could you provide picture(s) or drawing(s) of bearing plate doublers?

Thanks!

Re: Robowrangler Sheet Metal Giveaway Round 2
 

They can actually be seen in the picture linked in the original post for the Renegade Drive rails. Looks like the sheet was just doubled up and riveted together. Link copied below.

THANKS, Bailey!

Re: Robowrangler Sheet Metal Giveaway Round 2
 

Very interesting, can you share in the details of the gearbox design and ratios you tested. It seems a number of teams had varying success with the 775pros in drivetrains during the 2016 season. Thanks again.

Re: Robowrangler Sheet Metal Giveaway Round 2
 

It probably needs it's own thread to do it justice, as it's a pretty big subject and one that would be great to have some of the other users( I know 148 did not use them during the competition season) such as 3360, 16, 1296 and 3310 also share their thoughts( if they want to) in. Probably better to create a new thread than hi-jack a new one with what will inevitably be a big discussion that will be highly referenced by teams searching the forums in the future.

Re: Robowrangler Sheet Metal Giveaway Round 2
 

How funny, we've been doing the same thing. A lot of our old laser cut sheet metal from back in 2004 is now destined for a new home.

Except in our case, there is no new building we're moving into, and our stuff will likely go to the scrap yard to eventually be melted down.
