Hi, I am a mentor of a newer, relatively small robotics team. As a result we have never built a shooter before. I am looking for examples, specifically regarding an adjustable shooter. What are the pro and cons of a fixed vs adjustable shooter? Any examples or information about adjustable shooters for newer teams? It appears this year that it could be very difficult to shoot into the inner port from the “safe zone” right in front of the scoring objective. Does this make the trench run the most reasonable area to target the inner port from? thanks in advance

Hi, I feel we have the same issues. But there are already many posts about fixed and adjustable shooters. We’ve been looking at previous shooting years on youtube, then searching for posts referring to the designs we feel are achievable by our team. Obviously, an adjustable shooter will suck limited resources away from other objectives. The secret is balancing complexity with abilities of your team. I feel the best results come from defining an achievable strategy. You may find your niche within the assessment by 4607.
If you haven’t made a shooter before, consider doing something simple. If you want it to move in the up/down orientation, choose 2 positions to shoot from and do it pneumatically to a hard stop. This is much easier to tune in - only two speeds and you don’t need vision to calculate the elevation to the goal to determine the angle and speed you need.
If you’re talking about horizontal adjust-ability, then the answer is a turret and it’s an all-or-nothing proposition. You can turn your robot to aim at the target, but the actual action of turning will be far more difficult to get accurately by turning the robot. Turning just a turret has a number of advantages - no real static friction and a lower mass being one of them. Of course, the front goal is quite wide this year, so it’s much more forgiving than some other years, like 2012 and 2016.
