Hello all, i have been at this for a while now and have been unable to achive this. What im wanting is to be able to get the rings onto the mobile goal from the track system. We are short on length and can only go to half way onto the green rubber peice on the mobile goal Does anyone have any ideas?
Many thanks
I would recommend seeing if you can have your clamp tilt your mobile goal towards the robot.
Once you have done that describe other problems you are facing with scoring on mobile goal and think of ideas that might solve it.
Missed this part - the rubber paddles will not follow downwards enough to seat the ring on the goal (definitely make sure the stake is tilted towards the robot).
You can have a long chain to follow the stake vertically for a bit. Some teams use rigid hooks vs soft paddles to make sure the rings are seated past the rubber top in a scored position.
Prototyping is your friend.
Thankyou for your reply, we have tried alot of things including having stand offs and bearing blocks to flick theme on to no sucess,
Time to take step back - make a proof of concept mechanism (not on your robot) of your conveyor belt moving ring up to stake tip.
Your current one only has two roll points - one attached to motor driving, and second passive.
What happens when you add a third roll point with shaft that will provide a liner vertical drop (does not need to be long)? Does it pull ring further down into stake?
So, I think pictures of your iterations and data will show effectiveness of pathways and difference between rubber paddles and hooks when you post.
I say this because what I am observing about approaches and understanding of desired motion by other teams and past competition experiences.
I also hear your frustration - I would recommend reaching out to local teams in your area so you can have an in-person critique of design/implementation.
Your coach should be able to get in touch with local teams through the RECF RSM.
This would make a good entry into your engineering notebook:
- You have alredy identified the problem, being that the intake cannot score the ring/dorb onto the stake.
- Now you have to brainstorm solutions! Part of brainstorming also involves research - chances are, out of the thousands of robotics teams out there, someone has found a solution and published it.
But going off of your images, if that is how your stake is clamped, it needs to be angled inward to the robot more (problem subsection A). You can accomplish this by pushing the lower bar the goal sits on outwards, and make the clamp clamp down lower.
Then, there are two solutions people have found from there:
- Hooks (nice tutorial by 9motorgang)
- Hoods (skip to 3:00 , by FUN RoN & 229v)
