2011 Logomotion Mini Bots

[TJ Cawley]

what languages can the FTC robots be programmed in? LabView?
there is no FTC team in our area that we know of so i am tryin to find our option

[davidalln]

I haven't done extensive research on the subject (and unfortunately the USFIRST website, which I assume would have the answer, is down), but if the setup is the same as regular VEX you have the options of RobotC, EasyC, or LabVIEW. This may be inaccurate, however.

I'm guessing that the following site will have the answer (when the server is back up): http://www.usfirst.org/roboticsprogr....aspx?id=18758

[TJ Cawley]

thank you. do you have any experience programming the VEX bots with labview?

[davidalln]

Actually, it looks like I was wrong. A quick Google says there is no easy way to use LabVIEW with VEX. It looks like your options are RobotC or EasyC, at least one of which I assume will be with the software.

[ThePeracha]

Is RobotC or EasyC based off of C/C++ or something? Does anyone have an example of a program source code in that language?

From an FTC website: http://sites.google.com/site/ftciowacoaches/software

'The LEGO NXT bricks can run on one of three software programs: NXT-G, LabView or RobotC. However, to compete in an FTC competition, teams must use LabView or RobotC.'

I understand RobotC is text-based; NXT-G is a simple visual LabVIEW-type language but not allowed in FTC. Good Q for Wednesday: does the FTC programming rule apply, or can we program in NXT-G?


The Oregon FTC/FLL website ORTOP also has info. http://www.ortop.org/ftc/

Is there any real advantage to having code on the minibot?

Because everyone knows that code just ads excessive weight.

Would a bot that would just start when it knows the pole is there work better than something that the drivers would have to control?

[TJ Cawley]

software, or code, has no weight. for any robot to move, it needs code. otherwise, to get it running would be direct control between motor wires and battery, which is illegal

Are you sure? Why couldn't one simply leave it running forward, until it hits a switch, then drive in reverse? (Assuming they don't have to stay at the top)

that would take code. we do not have self programmed parts available to this competition. no code, no movement.

plus, that means your minibot would be running the entire autonomous and teleop match, leaving no battery life left

Can you cite the specific rule that forbids this please?

I could not find a specific rule on this, so it MAY be legal, but if your minibot runs the entire match, you have no power when you need it to climb the last 10 seconds

not necessarily, you could have a three way switch that connects the battery directly to the motor forward, backwards, and off, and the main robot could turn it on, deploy it, it would hit the top, flipping the switch, sending it in reverse. No wasted battery, no code

Exactly. The minibot rule section states you can use some common household light switches. Seems trivial to set up your deployment system to flip it on as it goes up.

Even if you left it always on, I don't think ~4 mins will kill the battery. Then again, I don't know the life of these batteries.

The NXT may be programmed in LabVIEW. There are libraries available, and it is easier to program then the cRIO. FRCmastery.com is the sister to FTCmastery.com. There are videos and help on both sites.
