...then why can't we make some sort of robot thing! You would type instructions on calc, which could then be sent to motors! (jimbauwen, his calc, and his mighty Arduino could surely do it :D)

With Ndless, we could do this, and could we get info back from the robot?

It would probably be just a simple car setup with four motors, two on each side.
The motors have to work like this:

DirectionLeft motorsRight motors
ForwardsClockwiseCounterclockwise
ReverseCounterclockwiseClockwise
LeftCounterclockwiseCounterclockwise
RightClockwiseClockwise
this is my signature

it's boring, just like me

Of course we can make a robot with it :)
I'm currently investigation different ways to send data back (with ndless you can have both direction communication, but noT with lua). I've got an idea, just need to do some research :)

Edit: big mistake: now-->not

I actually have a robot that can receive commands over rs232, I'll have to try this out.

Funny, I had the same idea :-)

I'll definitely make a robot of some sort soon, when I have my dock connector (maybe I'll make one maybe I'll do something else with some official cradle that I will dismantle.... :P)

I have this robotics kit from here (the level 1 kit), but this is quite doable with an arduino.

A robot would be nice. If someone manages to do it, be sure to post a video of it :D

I remember in 2005 or something, someone at MaxCoderz made a TI-83+ robot once, controlled by an ASM program.

A Nspire controlled bot would be amazing. It would be a great "look what I can do with my calculator" thing.

For controlling program on calc:
Should you make a list of instructions then send it to the robot for execution?
-OR-
Should we be sending instructions in real time?
-OR-
Include both functions and let the user choose which.

GUI:
Icons and buttons
-OR-
Console-like interface
