This is a 1/6 scale model of a much larger linkage in use on a robot. Directly actuating the linkage would require a huge gear reduction, and using cables allows for a smaller gearbox+motor due to the force multiplication of using a small pulley. The large scale linkage will also be using a spring assist.
As stated in the video, if you reduce the mass of the system that has to move while scoring, you can increase the velocity said system, in theory leading to faster cycles. In a lot of ways, the motion is simpler than a set of linear slides. Overall robot complexity is increased tho
@@hadleyarch9632 Is the difference in mass you reference simply the different between belt vs. linear slides (likely steel/aluminum)? It’s been proven time and time again that linear slides can in fact be very fast [hOw’D yOu GeT yOuR sLiDeS sO fAsT??]. I’d rather simplify the robot to a) reduce complexity for easy repairs, programming and reducing points of failures and b) keep the robot size small to be able to maneuver the already cramped field.
@@quinn.mcginley Definitely a concern I had! As noted in the video, I expect the meta to be slides or DR4B. I decided to posted this concept because I thought it was fun and different!
Excellent ideas! I was thinking of a virtual 4 bar myself so it could go 180. I was also thinking of having a larger contact area with the carousel, maybe through multiple small wheels, or like you suggested a curved belt. The only thing I want to point out is you are not allowed to move around the goals, so you cant add those servos to drag them around. Other than that great video!
Thanks for the comment! Yeah RIP moving the goals. Based on the recently released RI3D and RI30H protypes, I think slides will likely be one of the metas this year. A V4B could work, but based on previous games, I think slides will end up being faster.
