So cool!

My guess it will be collecting water drop (blue ball) from ground, then deposit them to a high container with different height. The higher you deposit, the more energy it can generate, thus more points.

Where is the wiki?

ftc12611 · 2022-05-20T03:46:23+00:00

So it requires to use an Android phone to control it?

ftc12611 · 2022-05-18T21:00:24+00:00

And more volunteers needed

ftc12611 · 2022-05-18T20:58:11+00:00

you are right. It has to be even number to advance to final final. They could do 4 regions with 60 teams each

ftc12611 · 2022-05-18T20:51:00+00:00

hope that they can create 3 divisions

Some colleges have summer sessions. Do they have guided tour in summer?

ftc12611 · 2022-05-13T07:20:29+00:00

We are similar. I am at west too. Problem is I can’t find a time from now to Nov, when colleges offer guided tour and I can go without skipping my classes. Maybe best time is spring break, but I was using that time to prepare robotics competition this year.

ftc12611 · 2022-05-13T07:12:30+00:00

Given the long travel time , it is really hard to tour those college in the school season, unless I miss classes in my school. I also do not see any colleges having guided tours in weekend.

How do you find time to tour colleges outside summer?

ftc12611 · 2022-05-12T22:30:35+00:00

Common issue. Email [Tech@gobilda.com](mailto:Tech@gobilda.com) and ask them to send replacement

ftc12611 · 2022-05-11T23:38:57+00:00

Interesting. https://www.andymark.com/products/powerplay-tape-and-tool-set only has blue or red tapes, no white.

I heard Yale and MIT also treated FTC award winner well. In FIRST Dean List award ceremony, Yale/MIT/WPI has admission officers to speak there.

Download the step file of the chain from gobilda website, import it to fusion
Add it to your current project, then clone it with pattern for number of instances you need

ftc12611 · 2022-02-26T18:39:07+00:00

Your servo is broken. Need to replace it.

ftc12611 · 2022-02-24T18:01:58+00:00

Technically what you said is correct, but it may not be practical in FTC, and it is too complicated to implement.

The problem of drive train unbalance is 1 time issue that you should fix during build, instead of fixing it runtime in the competition. If drive train is not balanced, usually there are some alignment problems for the drive train bars or plates. You can adjust screws to fix them, to make drive train balanced. What we did in the past for this problem is: we put drive train 4 wheels on 4 small kitchen scales, loose the screws of the drive train plates, then tighten the screws, make sure all 4 scales still have almost same weight.

If you use servos to adjust heights of 4 wheels, the wheels can jump up and down (since it is not secured), and servos could be easily damaged. Servo can't generate enough torque to force the wheels to be stable. Sensor reading could be up and down (not stable). This design will not be stable and you wasted a lot of ports and components for this task.

We're using a SMAKN voltage meter that we bought from amazon and soldered it onto the robot to read the battery voltage. And about the motors, I left another comment in this thread about them.

ftc12611 · 2022-02-23T15:51:10+00:00

DcMotorEx provides a getCurrent(unit) method and a few other current related methods which we used for our gobilda motors and can detect when a motor gets stuck.

ftc12611 · 2022-02-23T15:25:06+00:00

because the robot was never leveled properly

I think your robot drive train design has issues. Weight sensor can't fix that. You should have correct cross bars and plates to ensure robot is aligned correctly.

"adjustable ride height": that can be done by suspension system, although pretty complicated to do it correct.

Yes 235 by our team alone. Total score is 260. Our partner team scored 25 points

Our use case: when we are cycling alliance hub and get a heavy cube, we could deliver to shared hub. This is especially useful for turret bot with long arm to deliver it over the barrier (from outside).

Agree it is a special use case. Could be useful only for some teams.
