Intake Using a standard roller and a second roller of mecanums was an interesting approach to centering the ball. Worth investigating by teams to see if the front roller in necessary. Love the lexan flaps to prevent the ball from getting sucked in too far in an uncentered position. Very nice and simple trick. Teams, please always test your intakes on carpets. Ri3D teams may not be able to do this in their tight time window, but this is a must for all teams. You don't want to put your robot on carpet at competition and be surprised at how things work. Spoiler alert: it's soooooo different Karthik
Intake Lots of simple ideas to follow and areas to improve. Actuation with pneumatic pistons is easy to implement and this design protects them from damage on the field. Options to change roller height above the ground by adjusting cylinder mounting.Motor is protected from stalling by using belts that will slip if their is jam.Open to iteration with easy spacers and wheels to change out.Exploring different wheel sizes, types, and location can improve effectiveness but this design allows for those adjustments. I really like how this intake is used to line up shots, serving a dual purpose. This is a straightforward and effective way to intake balls. Many succesful teams will have something similar in concept to this. The most succesful will focus on the small details to amplify the performance Mason
Shooter (2pt) Two 775pros through a VersaPlanetary geared down 4:1, with AM compliant wheels. This is a really simple shooter setup that is worth investigating by any team who wants to shoot high, but isn't sure how. The VPs allow you to swap ratios really easily based on your testing, and AM has a huge assortment of different wheels that can be used in this setup. Love how they used the intake as a hard stop to get the proper spacing from the goal to be in their sweet spot. Shooting from this spot is very smart in general since it's protected. Relying on open field shots will be generous when teams play defense (which doesn't seem to happen in some regions, so YMMV) Karthik
Shooter (2pt) Simple design that allows for easy adjustment and iteration. By utilizing off the shelf components this design can be implemented by teams with very limited resources. Great choice to use the intake to line up shots from a protected zone. By focusing on a single location to shoot, the shooter can be optimized. My favorite shooter of the Ri3D for this choice. Mason
Control Panel Since the robot is designed to go under the control panel, some kind of upward actuation was needed to hit the panel. This was a really simple and smart way of doing it. Great solution that can be implemented pretty easily. Interfacing with the edge instead of the top of the wheel was creative. I like that this mechanism can be used whether they come at the control panel from either side, without any real tradeoff Karthik
Control Panel Elegant option for actuating the roller up and spinning the panel. Without adding any extra frills, this effectively will score points and is not difficult on the drive team to line up. One of the hidden challenges of the control panel is lining up a small mechanism on the robot to the panel. This design allows the wheel to be deployed and the driver to simply drive into the wheel. Regardless of the robot misalignment, the single wheel will make contact and score points. Great idea Mason
Hang Nice hang, but I wonder if the sway you get from hanging off a non rigid member like this will make it harder to balance with a partner (or even alone?) One of the biggest challenges with hanging this year will be lining up the robot. This seems like it could twist, which would make lining up even harder and less consistent. Karthik
Hang By detaching the hook, the structure to support the hang is greatly simplified. In this case PVC pipe and springs play a key role in deploying the hook. The force to support the robot is transfered through a rope and winch which is simpler to integrate and package. Coating the hook in a high traction material is a key to not sliding on a bar. The hook starting laying down opens the capture area quite a bit. Having as much capture envelope as possible makes the driver's task easier and will lead to more success on the field. Hanging by a rope will allow for robots to hang next to each other with reduced risk of breaking robot parts. Mason
