As a first year something that I don’t think I’ve really seen with VEX bots are mogo claws; I believe I’ve only seen one. I know there are just as much non-passive as passive claws out there, but do you guys know of some robots like this with a claw for its mobile goal lift or is there a very obvious reason that I’m not seeing this with Vex and I’m just oblivious to it?
Yes, a very good Washington team has a claw like that (I think 170A). Or at least they were testing one.
Forget exactly where i saw it, but there was one on youtube that was really good. It used the same claw for cones and mobile goals, really fast, but no way of internal stacking.
this is what I’ve seen as well. A don’t really see the advantage of having a claw just for mogos. the typical slide in intake works well, it’s simpler than a claw and doesn’t need a motor or over complicated passive mechanism. If it’s just about making sure the mogo doesn’t slide out there’s better ways of doing it. now if we’re talking about for an external stacker with a claw for both cones and mogos, it makes more sense, but then that get’s into the argument of internal vs external (I think internal is a much better option).
If you’re trying to keep mogos from sliding out you can’t use some non-slip matting or just a standoff that hooks onto the mobile goal while it’s on your robot like in this video.
yes it was that one
I believe that was one of the videos that I saw
At a tournament in my hometown that I reffed earlier this month, there was a team from Chattanooga that used the same claw for both cones and mo-goals. This team went on to win the tournament and qualified for state.
As for MG intakes, my teams have done well with passive intakes and passive up to 2 motor lifts (yes we have had a passive lift that can score a 5-6 bone stack in the 10). There is no reason I can see to need a claw to grab the mobile goals. Robots move much easier with a lifted mobile goal (floor friction is bad)
As for internal vs external,I think the winning alliance at worlds might need both. Internal is way better for control loads, but if NBN taught us anything this game is about who can get the most cones off the floor. Speed in cycle time is essential. External stackers may be the way to get that speed.
I don’t know if I agree with the external stacker part. From what I have seen, it takes more skill and speed to operate an external stacker at the same speed as an internal. So if you have a driver with a given skill and speed, I think the robot would be faster with an internal stacker.
that iz… 7090… went to ASIJ and saw them get the 184 skills score with the claw that grabs both… that was insane
It’s definitely not a bad design for Skills. I would question the dual-purpose claw’s long-term viability in normal matches with high stacks, though.
true true… been working on both to see which is better. Its just that the “standard” design this year can be beaten by such claws if the speed is optimal though
