Let's Make Robots!

turtle challenge entry!


my e-mail is neblick@westnet.com.au

this is my turtle bot that is made of that wonderful yet failing lego!

it goes forward and awoids obsticals at as basiclly as POSSIBLE.

it will see an object less than 20 cm infrount then it will move back turn and then continue.

instead of having a castor wheel i use a touch sensor.

when the souch sensor isnt being touch it waits 2 seconds (so it knows its upside down) then flips itself over.

lets have a look. (its not working so go to http://www.youtube.com/watch?v=DRe2C2Q1bpM)


i hope i get those tracks!

hope you enjoy the updated robot.

ive just realised a really bad fact.

my robot doesnt qualify.

its meant to flip itself over. in the vid i flipped it over. it only flips itself back.

so if no one else enters i may have a shot at it? perhaps im still in it?

update #2

ok i ve reamped the robot to your requests frits and i hope you like it.

i also made it so odly shaped that it has only two ways that it can fall, upsidedown or on its feet.

in one of the videos the robot is unable to flip itself over but thats only cos its running on 2 rechargable AAs.

i gave it a little help that was in the third video.

dick smith rechargable bats are great!

It sure looks to me like we have a winner for the turtle-challenge!

Has anyone got any protests?

nop, i think this lego turtle its preaty able to turn itself. next one that Nebster will to, will be a tank =P

i think i need to prepare my robots to avoid Nebster's ones ^_^

the main problem of humanity now is programing.. we have strong motors, we have nice video cameras, we have nice speekers, gyrascope, acelerometer, sonars, radars, a infinity of sensors, but we don't know how to program them well.. if we do.. we can make machins better then people.. so we need to bet in programing!!
ups.. yap.. =P

you mean LDR (Light dependant resistors) and like have them in a tiny tube thing so they are not affected by outside light.

but would take a lot of programming for the codes.

well you can integrate lego NXT with more things, like use it to make some part of the calcs, or motion, and use picaxe or arduino for more things

if you don't have other ways to comunicate betewne platforms, you can always make a led with a LRD (ligth variable resistence) to make them talk.. (like turn on or of a ligth you can switch to 1 or 0 a signal, that the other platform will know what it means.. just put all inside a black box, and your connection is done..

its ok

but ut has a lot of set backs in programming. notice how choppy my movements are in vids.

i would like some more sensors and more motor outputs etc. but just not possible with this. =(

i was implementing a acelerometer in mine =P (i dont have lego NXT to play T_T)
thanx it also came to me because i was to lazy to make a caster wheel. lol =P

gratz, simple and working =P i like it ^_^

really nice idea of puting the 3rd well as a sensor to know if is upside or not =]
