Post Einstein Report Observation and a Question (not more of the same)

[Chris is me]

The FCA exploit worked regardless of programming language used.

As for 25, they had a bright flashlight on their robot that the drivers would use to line up shots manually.

The observation about programming was not meant to tie in at all to the report implications, per se; I'm just surprised the zero of the top 12 used Labview - wonder the the odds are for that? On the question, do you know they used the spotlight for targeting or is it that conjecture? If that's all you really needed (and it sure seemed to work for them) then our team spent a lot of time and energy on a far too complex solution!

Both 180 and 25 used flashlights to help their drivers manually align their shooters.

So you had a flashlight shine at the retro-reflective tape, and from there your drivers could tell if they were aligned? Did you use a specific type of flashlight?

Basically what they used was a huge searchlight(IIRC it actually is a search and rescue light), so it was basically a crosshair that was a huge shine of light that they could look at.

Correct! There was some discussion on this topic in the "Why didn't we think of that?" thread. In short, 25 used a small halogen headlight and 180 used a modified LED mag light.

Haha, it's a lot less blinding when you're on the same side.

Thanks!. Sorry I missed that thread....what an ingenius idea.

Like Kristian said, it was just an LED mag light that you can buy at Home Depot. If you focus it down all the way it makes a dot about a foot across that you can see from the driver's station (Yay for smoked Lexan backboards).

Left and right alignment was obvious. The cool part was that the light was mounted at a fixed angle and aimed at the top goal. If the dot was too high, you drove forward; if the dot was too low, you drove back. Our shooter wheels only ran at one speed all year long!

Thanks for the advice George, Kristian, and Steven!

George, do you happen to know the model flashlight you used?

[Akash Rastogi]

Yup 25 is a really BRIGHT group!






I'll walk myself out.

I don't remember, but I'm not sure it's really important. The one we used was way stronger than it needed to be. You could see it on the roof of the dome when we drove around the field...

Our prototype entailed attaching the Photon Cannon (flashlight) to the robot with the Photon Cannon Mounting Device (a lot of duct tape). Just take any flashlight with a focus lens and tape it to your bot. If you like how it works, figure our how to mount it permanently and wire it to run off the robot battery instead of it's own batteries. Sounds like a nice little off-season project.
