FIRST Robotics Competition Team 5817 "Uni-Rex" 2016 Robot Reveal: Ankylosaurus
 

FRC Team 5817 "Uni-Rex" is proud to present our FIRST Stronghold robot, Ankylosaurus.

This robot is the result of over 2000 hours of student time, and we are very proud of our team for getting this done in our first official year with FRC.

None of this would be possible without our parents and mentors, as well as our sponsors: POM Wonderful, ADCO, Sanger Unified School District, Sanger High School, SunBurst, Solidworks, Cap's Coating, and Electric Motor Shop, as well as many other generous donors.

Our robot is made almost entirely of 18 gauge, black powder coated stainless steel, with some custom designed 3D-printed parts.

You can watch our official reveal video here.

You can watch some additional footage here and here.

And just for reference, this is what an Ankylosaurus looks like.

Woah!

This looks so impressive from a rookie team! That shooter is so powerful :eek:

A rookie team... Finished robot that can complete major tasks of the game with 17 days to spare. With a functional swerve drive. Am I overreacting or is this possibly the best rookie team ever? :eek:

(Not to mention the gorgeous anodizing).

It is clear from the video that you have an Omnidirectional Drive, from the pictures and video I can't quite tell what it is can you elaborate?

Re: FIRST Robotics Competition Team 5817 "Uni-Rex" 2016 Robot Reveal: Ankylosaurus
 

Very neat. How are you getting so much power out of 2 cims for the shooter though?

Re: FIRST Robotics Competition Team 5817 "Uni-Rex" 2016 Robot Reveal: Ankylosaurus
 

We are using a 4-wheel swerve drive based off of 221's Revolution swerve. All the parts were sourced by the team and built in-house. They have worked pretty well so far. :)

Baby swerve modules (and our offseason robot in the corner).

We are running a MiniCIM on each side, geared up at a 2:1 ratio. It puts the motors near the peak of their power curve, and we have seen up to 7000 RPM on the output.

Re: FIRST Robotics Competition Team 5817 "Uni-Rex" 2016 Robot Reveal: Ankylosaurus
 

We have a swerve drive setup with skids designed into the frame to allow us to climb over the defenses.

We are actually only running mini cims, we went through several prototypes getting the most powerful shot we could.

Re: FIRST Robotics Competition Team 5817 "Uni-Rex" 2016 Robot Reveal: Ankylosaurus
 

Really impressive, especially for a rookie team. My only worry is your shot may be too powerful, if you hit the top of the goal it may bounce out even with the chains.

Re: FIRST Robotics Competition Team 5817 "Uni-Rex" 2016 Robot Reveal: Ankylosaurus
 

Just out of curiosity, how is this calculated?


Also, in regards to your drive train, how many of the defenses can it cross?

Re: FIRST Robotics Competition Team 5817 "Uni-Rex" 2016 Robot Reveal: Ankylosaurus
 

We have students log in and log out at each meeting. We have 12-15 active members, each put in up to 200 hours.

We can cross all of the defenses including the low bar, although some are more difficult (a result of using 3.25" wheels). The ramparts are the toughest for us, although we only began testing on it yesterday, so that could change. I don't have any video to show you as of now, so you'll just have to take my word for it. :D

Re: FIRST Robotics Competition Team 5817 "Uni-Rex" 2016 Robot Reveal: Ankylosaurus
 

6 of the defenses are very easy for us to accomplish. The two easiest by far are the low bar and rockwall. The remaining 3 defenses are more difficult. However we have successfully driven over them it takes some driving practice to know how to approach each one. We have a practice bot that will allow our drivers to work on practice more and more after bag and tag. As well as finalize our auto.

I don't think that bouncing out will be a problem, we have noticed that the balls lose a lot of their energy after hitting an object. And the spin will help it go in the down direction.

That looks great, what the experience level of your mentors on staff? I see some old school design features in the robot. :p

Re: FIRST Robotics Competition Team 5817 "Uni-Rex" 2016 Robot Reveal: Ankylosaurus
 

They are an offshoot of 1671.

Re: FIRST Robotics Competition Team 5817 "Uni-Rex" 2016 Robot Reveal: Ankylosaurus
 

We have two mentors with >5 years of participation in FRC. They have been a huge help with the organization and planning behind the team.
