2910 Robot, 2022

Simply amazing watching yourselves + 2046 both together and against each other at PNW Bonney Lake, congrats on the win!


Is there a full video of the auto at Bonney Lake? The PNW recordings only show the cargo going in.


Just amazing!

TBA doesn’t automatically get the wide versions of PNW streams. If you click the little “Search on Youtube” button on TBA usually the wide version pops up. Here’s QF1-1 Wide for example, not sure which matches the 6 ball auto was used.


Here is the full field view of a match where we ran the 6-ball auto.

Here is a better view of of the 6-ball auto.

Our shooter belt came off at 65 seconds left in the match when the blue bot popped a wheelie onto us. Once we figured out why it wasn’t shooting we played some defense. 2046’s climb is so good.


2046’s climb is ridiculously good and fast. <— FIFY :wink:


That 6 ball is so fun to watch! The speed and fluidity in all aspects of your robot, programming and driving are inspiring. It was rough going up against you and quite a pleasure when we were with you. I’m looking forward to seeing your team again and all of the other great teams in the PNW this weekend.


Hey is there any chance you will be releasing the robot cad at some point?

Yes, absolutely. The CAD is actually in a pretty complete state. Just needs a little bit of tidying up and it will be ready to make public. We should be able to release it within in the next week or two.


Brilliant performance this year 2910.

Question though… Now that this whole official season thing is behind us. At max swing on the trav rung, when it looks like you are going to launch above the alliance wall, are your bumpers outside of the plane of the driver station wall or does it just look that way?

No part of the robot ever crosses the plane of the alliance station wall. The robot is too short at that point to reach that far. It is pretty cool to see a good portion of the bottom of the robot above the alliance station wall from behind the glass. And if another team was in alliance station one we typically would let them know what to expect.

Most of the time throughout the season we weren’t going all the way up and hooking the hood on the transversal rung, but we ended up doing it a lot at champs because it allows more clearance for other robots to climb behind us on the mid or high rung.


Awesome robot, had a blast playing with you guys on Newton and Einstein!


Sweet I can’t wait.

CAD Release!

CAD files of our 2022 robot Thor as it competed at championships are now public on our GrabCAD partner space.

Well that was quick!!

This is so awesome, thank you for doing this! I always look forward to seeing your team’s CAD releases, the detail is incredible. What program do you all use for CAD?

I had a quick question, the hook circled below, is that to keep the climber stowed? Does it start the match latched? If I’m guessing correctly, when you climb, you pull down the climber slightly to clear the hook then run the intake to un-latch, then un-winch to extend?

You are correct. The constant force springs are enough to back drive the climber gearboxes when the robot is turned off. Those hooks are to prevent the climber from extending. The hooks are spring loaded with some surgical tubing (not shown in the CAD). When the match starts the robot homes the climber to the down position and the hooks unlatch allowing the telescopes to extend when we are ready to climb.

What gear ratio and/or strength of CF springs did you use?
We had a similar set up but nowhere near enough spring force to backdrive our gearbox. Though we had less stages on our telescoping arms than 2910 so that would reduce the spring force.

Each stage had 4 of these 2.3 pound constant force springs 9293K263 per telescope assembly. So a total extension force of about 18.4 pounds minus the weight of the stage.

I think the main reason why they were able to to be back driven was because the gear ratio was pretty aggressive. 13.2:1 on a ≈2"D pully.

Having more stages doesn’t inherently increase the extension force. For example if you have 1 constant force springs on each stage of a 4 stage elevator (total of 4 springs) your extension force is not going to be any more than the force of 1 of the springs. The springs are in “series” not “parallel”.
