I haven’t seen a low boiler robot yet! :ahh: This is so cool! Good luck this year!!!
And 3683 builds another simple, yet scary robot. 2502 had a great time with you guys in Galileo Quals, and against you guys in Galileo Semis.
I always love when teams keep it simple, and execute simplicity perfectly!
Awesome!! Glad to see someone other than us focused on the low goal and gears.
I’m so stoked to see a team who executed at such a high level on the low goal!
Can’t wait to see it in action.
I had originally wanted my team to go in this direction but the students wanted the high goal, glad to see someone pulled it off…

Is it just me, or does it look like that hood is adjustable to shoot up to the HG too?
I noticed that as well. It almost looks like they attempted to shoot high in the beginning. Had issues with their shot and ultimately decided to shoot low as it would gross them the most points.
Regardless looks fantastic. Good luck!
That hood (or entire shooting apparatus) appears to be able to actuate. Pneumatic cylinder or something. Is that for your climb? Other things in mind? Or perhaps my eyes are fooling me.
Also, hello from your neighbors! Our robot is not nearly as impressive as yours, in it’s current state.
Edit: I just noticed the two comments above me, the problem with getting distracted with work things partway through composing a post. (I was thinking maybe high goal as well, just that angle is strange. Could just be perspective.)
Potential feeder bot situation
The hood assembly does actuate up and down via pneumatic cylinders, this holds two purposes. First is to actuate our climb out and the second being to feed other teams over their hoppers.
Nice looking robot this year, I’m curious about your active gear delivery, do you have any additional images or description of the system, it appear to be two L-shaped pivots actuated pneumatically?
Nice low goal solution!
That’s awesome! I love bot’s that specialize. Do you guys have a practice robot this year? If so, our teams have got to meet up before Waterloo.
Good luck this weekend! We’ll be watching the stream and cheering you on.
Looks nice, but it also looks like you have stuff outside your frame perimeter and doesn’t look like it started inside. Specifically the air tank and it looks like the uprights are canted outward over the bumper. Remember, at start of the match, everything except bumpers needs to be inside the frame perimeter, not just inside the max volume.
I’m assuming that’s because this is the “expandable” hopper - it starts the game inside the frame perimeter, then expands out once the match is started.
The Hopper expands over the bumpers using a four bar linkage and surgical tubing and starts the match fully inside the frame. This picture was taken of our practice bot which has a older version of the hopper. On our comp bot we have nylon webbing hard stops that stops the hopper from expanding past the bumper.
This answers my question. 
See you over the march break!
Congratulations Dave yet again on an amazing build season! Can’t wait to see you guys compete this week and cheer you on as you progress through this season.
P.s Danny I love the signature, we all know Sven is clearly your favourite Dave mentor 
The gear enters the cage via a pneumatically actuated ramp and sits snugly between two c shaped claws. The claws are pneumatically actuated around a pivot point which forces the gear out of the robot and onto the peg.

We’re going to need to talk about this Dan.
