Hey everyone! We’re team 11101B Barcbots Getting There, and we’ll be attending the North Dakota Signature Event @ Mall of America this weekend. Here’s our robot reveal!
Robot Specs:
2 motor Intake
6 motor 450rpm 2.75" Drive
1 piston Aligner
1 piston Loader mech
Two-wheel 2" Odometry
Programming Specs:
Optical sensor color sort
Inertial sensor + 2 rotation sensors (odometry)
Feel free to ask any questions below!
How’d you make your nets?
Basically we used satin cord. we kinda made a rectangle with it, the top string had knots measured out so that there were holding each piece of string keeping them from shifting. We used lark’s head knots to attach the string to the top string. Then take two ends which weren’t attached to each other and used more lark’s head knots to tie them together, making a diamond shape, until we reached the bottom string in and tied them off.
Some videos might be able to help you visualize it, In addition here’s a photo of me making the netting. We used a warping frame to keep the tension even, since strings have a tendency of expanding with force.
just wondering, how much does the robot weigh? Do u think front to front intake will be optimal or cause difficulty on the driver? Are there any problems u experienced with basket jamming when unloading?
@Zayn_11101B, I’m curious, why did you choose to use 3 motors for your intake (11w + 2 5.5w) instead of 2 11w motors? Are the two 5.5w motors connected by a differential? We have a simmilar design but we just have one location for the long goal and high center goal. We thought this was the most efficient way, but we are seeing most teams going for this 3 motor version. What were your thoughts when choosing this?
Cool & creative. Well done!
how much does the robot weigh?
about 15-16 lbs
Do u think front to front intake will be optimal or cause difficulty on the driver?
Right now, we don’t see a major issue with front-to-front, but we’ll probably reflect and iterate after MoA based on our driver & robot performance.
Are there any problems u experienced with basket jamming when unloading?
We use an “agitator” mechanism in the basket which constantly moves the blocks around. This has solved all jamming issues involving the basket.
Isn’t the drive 3.25" instead of 2.75"? The video description says 3.25 and you can tell in the video.
6 motor 450rpm 2.75" Drive
Accidently wrote 2.75 when originally writing the post. The robot is using 3.25", sorry for any confusion
Can you please elaborate more on the “agitator” How does it work and can you order it through VEX?
We plan to implement this type of mechanism on our f2f bot too, but it’s not a set part, it’s just a way of moving the parts in the basket around to prevent jams. For example, we plan on doing this by using a mesh/sprocket roller combined with a rubber band/sprocket to reintroduce the blocks into the intake system to score.
Congrats on making finals! Do you plan on implementing descore after how much it impacted the matches, or will you completely rebuild for locals?
Can you share a picture of what you are talking about?
