Elevation at end of match

[Tman6000]

At the end of the match we have realized that when the timer runs out our elevation motors disable, does this apply to the competition, or is this a code problem, we have them set to hold

No matter what all motors are set to coast after a match in competition, you might want to consider using a ratchet (which might have to be pneumatic depending on what your elevation looks like.)

Hope this helps!

This is normal behavior. You will need to figure out a way for your robot to stay elevated at end of match.

Plenty of ideas on the forum - use the search function.

Or use a gear ratio that will stop itfrom falling.

Consider old seasons with similar tasks. Starstruck had a post in a corner situation, and many teams used simple arm to kind of do a curl up. A benfit being the position of the bot when power ends has it stay folded without ratchets or locks.

Think before you post. I have seen new users post blatantly incorrect information on the forum. Don’t just post what you think cause your friend Bob told you it is true. Try and find the source for what information you are giving (and maybe you’ll actually learn something new while your at it). And if you do realize something you said is wrong, delete your post. All you’re doing is hurting new users like yourself.

There is no realistic gear ratio that would stop it from falling. You would need some sort of lock because all motors are set to coast after the end of the match. However, this wouldn’t apply to a pneumatic elevation.

Topic I made a few months ago to look at.

Robots on the elevation bar at the end of match

At the end of matches they use the game switch to stop the robots from moving that way they can score everything correctly. If we were say using a claw when the match ends the robot would begin to slide or even fall. So i am wondering how it stays up while there scoring the match at the end. Is it in the building or programming

You could make a passive locking mechanism or a ratchet system on your lift(If that’s why your using) This is an example of a passive locking mechanism: https://youtu.be/F42B3qwYk1M?si=jRxEJIpYDeuRVd8t

Im using a gear ratio. Im sorry if you think its a bad answer and unrealistic but it is seriously the thing id do. If you dont believe me im more then happy to post a photo

[Money]

Sorry, I might have been a bit harsh.

I don’t fully understand the “gear ratio” locking mechanism that you’re suggesting. Could you please elaborate with a picture or explanation to help me understand? Thank you.

[jpearman]

Probably a large gear ratio, perhaps compound gearing. The weight of the robot is then not enough to back drive the motors.

But pictures would be best as an explanation.

[Money]

Ahhh okay…

When I was saying that there was no “realistic” gear ratio I was thinking about it in terms of my robot, which is on the heavier side (to put it lightly). I guess that could work with most robots though.

[Brainiac]

My robot weighs alot and works fine for me yes it is just a big gear ratio that the weight carnt over come ill get a photo in a bit

[Brainiac]

Sorry, forgot to get a photo. pretty much its just a small gear attached to a big one and ive got 2 of them. That is enough to hold it.
