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.

They something like this perhaps?

Remember to add a resistor of ~200 ohm before connect the LED to 9v.

For receiver, google op amp comparator and relay. You probably need LM358, BC 548 and some variable resistor to setup a standard comparator circuit, which you can use again and again in other tasks.

If I connected the receiver to a vacuum pump in the circuit for 4. b. i, would it be possible to use it without breaking 3. g.?

Would anyone consider using a Lego Spybot for the IR part where the remote button will be pressed and the motor on the spybot will pull a string to lift the final action as a programmable component? I used it at the last invite and the supervisor said he didn't consider it programmable and didn't make me take it off. I just wanted to double check here before regionals.

I thought the Lego Spybot was programmable - the motor block has a computer that you can program a bit like mindstorms, doesn't it? Perhaps you'll get lucky with the ES at state, but I think anyone who knew what Spybots were would rule it illegal.

That is the definition of programmable. Its unbelievable that an ES let you get away with it. How did you not consider that programmable?

The spybot isn't programmed though. It's like an rc car where you push a button and out of the box it just works like that.

It doesn't matter if it is out of the box like that. It has programmable components within it. I could program on some of those components to do things, this makes it illegal. A classic example is a temperature relay like the W1209. It is programmed out of the box, and is ready to use immediately. However, it is still programmable.

For further proof of this, look no further than the Wikipedia page for spybots. To quote that page "Each Spybotics set includes a CD-ROM software disc which allows you to program the spybots." and "Spybots are programmed primarily through the mission system, but they can be programmed in a similar manner to the RCX. Most RCX-compatible programming languages can be used. Programs are uploaded to the control module using a special serial-to-IR cable included with the set."

Ok guys I am at my wits end with this task. I have tried what I can but nothing I am doing seems to be working as it should. Could someone please explain/show me how they did their's? Keep in mind that I am very new to electronics and only know what I have learned this year (which isn't much). Dm me if you don't wanna tell the entire interwebs please. I kinda really need yall's help here
