Hi everyone hope you're having a good day. I was messing around with different end effector designs and I'm not very successful with picking up the ping-pong balls. Is the use of vacuum pumps to pick up items a feasible option?

What is the best way to regulate the voltage? With a 12V battery regulated to 5V and 12V with a high output of like 3-5 Amps.

With the battery voltage, Im going to purchase some 12V NiMH batteries. The 12V batteries are labeled 12V but when fully charged are 14.5V is that ok to use?

Rules specify nominal voltage. You're good

Ok, good thanks. I forgot it said nominal.

Am I able to use multiple different barrels and have them interchangable? Like have a barrel attachment that fits better with a ping pong ball rather than a tennis ball.

Okay so my partner and I have ideas but not sure on the air launching part? Is there any good videos we can watch or good places to find ideas?

I have read the rules at least 3 times. Can I do a catapult like design or what is a good way to make one like a stomp rocket.
