The Robowranglers are proud to present our 2021 robot, Kolibri.
Huge thank you to our sponsors, Greenville ISD, Innovation First International Inc., and L3 Harris, for their unwavering support during this unprecedented season.

That music sounds familiar…
Congrats on your win in Helium!
If you don’t mind sharing… what did the prototyping process end up looking like? Was there a specific reason you chose 4 wheels over 3?
If I had to guess…
Yeah that’d do it, and the battery is practically on the ground.
Tumbleweed seems to have shown similar issues, just not as extreme.
Uh? Not a nonagon?

In the video you state that you set out to build the fastest robot in your history. Looks really fast, but did you succeed at it being the fastest 148 robot (which is a pretty high bar to hurdle)? What is the theoretical free speed?
Looks like you have 2 drive motors per swerve module? Am I seeing that correctly? That would give you a lot of power to the wheels as long as you had sufficient traction. Any other tricks buried in there that you didn’t reveal?
Is triple-motor-swerve-module the new thing now?
If you don’t need motors/PDP ports for other mechanisms then why not.
I suspect it won’t go past this year but with the new PDP stuff coming out it’s possible that it could continue
The robot always looks great as always! Congrats to all of you guys on the amazing work and the win in the Helium Group!

Oh the pinion guards are just for wire protection…
And the bottom placement of the intake motor is interesting.
And I don’t see any vision system, I assume you played the GS odds.
The RIO is really hidden well. No bent sheet metal that I see. And fav feature has to be the zip tie attachment for the torsion spring.
Joking aside looks awesome as always, this robot is incredibly clean!
Nice work! Sick times, especially on the Lightspeed Circuit. That’s hella fast.
Great robot and times. That lightspeed circuit time is INSANELY fast!! Congrats on another great robot and for winning your division!
Awesome robot and very interesting swerve modules. I love how the video is a tumbleweed throwback. A couple questions:
Maybe my eyes are deceiving me, but are the drive motor pulleys a different size? If so, how are you using that to your advantage? Are they always receiving the same percent output?
How are you initializing the steering angle on the modules? I’m not seeing a steering encoder. Is it done manually on power up?

I figured hall effect based on this part that looks like a magnet holder:

Very nice team 148!
Congrats on the Helium Division Win from 5675 the 5th ranked team.

I was watching the reveal video again for Kolibri, am I still am confused what the point of the 3 falcon. If you look at 0:53, when they were showing off the swerve, only the 2 side falcons of the modules we active, the center falcons weren’t doing anything. Can someone explain why they have a 3 falcon? I assume they were using it as the encoder but they could have just used a CANcoder or something.

the center falcon was moving too they just had 2 falcons for every wheel
