Hey everyone! We’re team 11101B Barcbots Getting There, and here’s our early season robot reveal!
Robot Specs:
Feel free to ask any questions below!
For your guys doinker, are you running any PSI control on the piston? Cause Im having trouble with it hitting the ground on 100-60 psi.
We are not running any PSI control. The doinker occasionally hits the ground but the rubber bumper absorbs the impact.
Could you explain to me what the “doinker” is and what it is used for? I’ve heard the term here and other places but I’m not familiar with it. Thanks.
How are you guys using the tank tread to slap the ring onto the stakes?
The doinker is the arm we have on the front of the robot. It comes down using a piston, and is able to push rings and goals out of the corner.
As the intake spins, hooks that sit on the chain pull the ring directly onto the stake.
What RPM/gear ratio are you using for your drivetrain?
The initial post has specs written out.
66W (6 motor)
450 RPM 36:48
8x 3.25" wheels
All Omni Drive
check the first post.
Are you guys planning a build for speedway?
What code did you use for the drift at 0:47 in the video? Or is that just the omni wheels acting up?
Yes, we are planning a build for Speedway.
With an all-omni drive (and driver practice), you are able to drive the robot into a controlled drift. The segment at 0:47 in the video is not programmed, it is driver control.
Great robot, at this point in time it very well may be the best robot rn. I do have some questions, how much does it weigh, how much psi does it need to climb, how often in matches did you actually use the climb, do you have plans to do wall stakes in the future?
Around 16 pounds
The climb requires at least ~20 PSI, and uses up ~6 PSI per activation.
We used it in majority of our matches.
Yes
It depends if u have pneumatics then yes but if u don’t I would say no
would robot length be a con when it comes to moving around the field? 3.25 450rpm is rather long, did that affect driving?
Length of your robot may matter in some cases but, for most part, no. Most drivers just get in practice time with their bot to get used to the layout.
