great ideas for gear ratios

I agree wit Josh this is what we need for the project

this has some good ideas

this is good to show what gears to use

this is very useful in helping us decide which gears to use and what ratio to set them at

This might be the key thing for gear ratios

the robot designs on this page are possible for our criteria. the majority of them have a ramp like structure on the front for pushing and flipping

i wish i could see some of the videos but i cant right now i wanted to see if thee were any changes to ramp in general

the sumobotofdestruction looks cool and doable

this could be useful

thanks for pointing that out, i didnt want to say anything

it doesn't matter the theory is sound

^ this show an idea we can use for backing up when objects contact our nxt

its actually a pretty nice setup if we found space for the other sensors, but id stick with the back wheel we have now, it also shows how to make it very nicely

HEY

Shows how datalogging works

Use front panel datalogging to record data for use in other VIs and in reports. For example, you can log data from a graph and use that data in another graph in a separate VI. Each time a VI runs, front panel datalogging saves the front panel data to a separate datalog file, which is in the format of delimited text.

This is im pretty sure everything we have

That was a good idea declan thanks buddy

OK 0_0

sorta of a change in design than the last one i had thought was good

looks good

Great pictures Tommy. We can use some of these ideas to build our robot

LabVIEW Toolkit for LEGO MINDSTORMS NXT Program and control NXT devices with the full power of LabVIEW Get real-time updates from the NXT device during program operation with LabVIEW front panels Create native blocks for LEGO MINDSTORMS NXT software Figure 1.

this shows how the data logs work ( ._.)

Nice (o____________________________________________________________________o)

oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

datalogging

good info, but seems a little complicated

i dont think thats our program

this could work but what if the robot turned and started going the wrong direction back towards the start???? it only follows the walls which could lead the robot back to the start not the finish

anyrobot we do is basically going to be folllowing the wall though and it would have to go all the way to the end to start going back to the beginning

shows how to build a robot that follows lines.

line follower

All we would have to do is change those razor things out

how to use a worm gear

this will be helpfull

the way the ultra sonic sensor is set up is a good idea

I feel the way they set up the light sensor is a little to far out

we are gonna have to place the ultrasound or light sensor under three inches if we are following the inside walls, but thats an individule decsion. we could use a code similar to the wall following code in the romba project.

LabVIEW 2009 LEGO MINDSTORMS NXT Module Help Logs Data from the specified sensor connected to the specified port. The data logging parameters are sample time and total time.For the Red Vis, the data is stored in the RedData.dat file on the NXT brick and can be viewed using the Data Viewer application.

it explains how the block diagram needs to be set up to collect data and then input it to the computer
