Do you adjust the power or angle of the shooter for closer shots, or is it the same for both of the position you shoot from?
I completely agree. Additionally, when teams beginning clearing the field in some matches, like we are already seeing, it will probably be more beneficial to score the field balls first, so that the other alliance can’t score them. Then one robot can score the driver control loads and then possibly go for elevation before the match is over.
Interesting, thanks for the reply.
I can definitely think of some huge advantages in having a two motor launcher, as it seems everyone else is using 4 or more. It would definitely leave some room for a decent lift,
Would I be correct to say that 2R is using turbo motors on their base? We’re using high speed motors on ours, and its wonderfully fast, but not as insanely fast as 2R’s. (High speed motors are our limit, as our robot is somewhat large and heavy)
2R’s motors are on high speed, but also geared 1:3 externally as well. This gives the robot an overall 480rpm on 2.75" wheels and a speed of 5.7ft/s.
The robot never stalls out or overheats since it’s running 8 motors on the drive. The robot was built in 3 days and tuned for a week.
2Z changes just the power of the shot, not the angle for mid field shots.
wow nice job!
On 2R’s robot, how do you guys manage to feed the ball to the flywheel? Could you guys post a picture or is there also going to be a separate reveal later for them? Thank you.
The flywheel is fed using a conveyor like any other robot. There isn’t going to be a reveal, sorry about that.

How are your motors distributed?
We have 2 motors on the flywheel, 8 on our drive, 1 for intake and 1 for the conveyor.
could you post some pictures of your double shooter close up
Like the robot, but you were not scoring many balls around the field. Goes back to the great debate of NBN, catapult is better for preloads, flywheels are better around the field.
I disagree. There are many catapults that are great from the field such as Wingus and Dingus. However, I have not seen very many “punchers” that are great field robots, but I have no doubt that this type of launcher will get better from the field as the season goes on.
Hey! My photos haha, see you guys at Gladstone, you’ll see me driving and taking pictures. Feel free to say hi!
You need to reconsider. 2R’s flywheel discharged 4 balls in about 1.5 seconds. Catapults can only be loaded so fast, meanwhile flywheels can take balls at any rate, and are only limited by their fire rate, a fire rate that is higher than catapults.
The bottom line is that a catapult or LinearPuncher (LP) that can shoot full court will alwasy shoot slower than flywheels at mid to close court.
I do not think one design is “better” than the other. My team personally has a flywheel a have been using it with pretty good success this season. I think that either design could be great depending on how well it is executed.
BTW you have a great robot. I’ve enjoyed watching your matches so far this year and I can’t wait to see more as the season goes on.
Insane robot man! What is the gear ration on the flywheel that is powered by 2 motors!
Thanks! We had a 1 to 7 ratio on the flywheel.
How did 2R’s compression on the back of the flywheel, work. Could you guys post a picture of the compression with the plexiglass because I am having trouble figuring out the compression on my robot. It is also geared 1 to 7 but the compression is affecting how high it shoots. Thanks.
Adding compression will reduce fire rate. It is ideal to have as little compression as possible, and put rubber bands on the flywheel.
