Re: Infrared Task

Post by engineerandgolfer »

Hello all,

This is my first year on Mission, and I am in over my head with this task. What I am looking to do is have the golf ball from the start task land in a cup that would apply pressure on and close a switch, allowing current to flow to the IR transmitter. The receiver would detect the IR and this would allow current to flow through a relay to a motor with an attached blade that would carry out action 11 (fishing line task).

Is what I am describing possible with these components:

A lot of examples of IR circuits that I found online were super complicated and/or required Arduinos, which aren't allowed this year.

I could really use some guidance with this. Thank you for your help.

Does anyone think an infrared break-beam is legit? The rules don't ever specify that you must turn on the beam.

I was just thinking the same thing. They simply say to "use an infrared beam" to start the next action. Pretty ambiguous

Seems like it should work, although I am not a competitor so I may not be aware of particular problems others are having.
I would be worried about that blade on a motor - seems pretty dangerous if not properly contained/shielded and could get you DQed for safety issues - i would try to find a different solution.

I would attempt to break the fishing line with nichrome wire instead, if possible. You could hook it up to the same relay-switched circuit.

What type of infrared beam would be best? This is my schools first year competing and we need some insight.

Try raw IR diode. amazon: SUNKEE 10pcs 5mm 940nm LEDs infrared emitter and IR receiver diode 5pairs diodes.

So I looked into this item and does it not need to be programmed with an Arduino? Every time I find something, I realize it is an extension to an Arduino kit. If not, how would I assemble this? Would it almost be like completing a circuit?

Are you allowed to use breadboards?

Theres nothing directly against them in the rules, and I've seen some teams use them. Just make sure you are not using arduinos, or anything else that is against the rules and you should be fine.
