I know this is a bit of a silly thing to ask for, but as i just need about 20$ till i can order all the stuff i need to build my robotic arm i was just wondering if someone could give me an idea of what to make with a two wheeled robot with an ir sensor. Sadly thats all i have at the moment. I use a bx-24 chip and a RAMB II motherboard. Iv built many different things like object avoiding, tabletop etc robots. So has anyone got any ideas as to a concept that would push the capabilities of my current set up?

many thanks,

IR remote controlled robot ? Seriously, you could use a remote from VCR and do different stuff when pressing a button (like fast forward or sth). Just an idea

a two wheeled balancing robot (segway) and using IR to measure tilt by pointing it downwards.
the fun stuff is calculating the PID control...

thanks! those a brilliant ideas, ill probably go with the remote idea first! Ill go do some work on it now

make sure its a universal remote, not one from a specific tv!
this makes it ten times easier!

well im a bit confused, the tv remotes give of ir. So i should cover up the emitter on my ir sensor?

Just setup an IR detector to get the appropriate wave-lengths and then you'll have to devise a way to decode each signal.

how am i supposed to set up and ir sensor to receive a certain wave length, its just a standard sharp ir. It gives me an integer between 1 and like 400. It can see to like one meter infront.

Sharp IR sensor is to detect distance, its a rangefinder

IR remote, like your tv remote, emits data that is encoded in the beam of infrared light. The detector reads the beam of light and decodes the data.

ok, so how can i harness a sensor to some how output a differnt number for each button pressed on the remote. Im pretty new to like modding ir sensors and tv remotes etc

Might be a bit difficult for a beginner

thanks

, it would be useful if i had the stuff now. But i dont

so ill perhaps try the balancing robot thingy

For the balancing robot take a look at my tutorial:
http://www.societyofrobots.com/member_tutorials/node/185
The Ping sensor can be replaced with a Sharp rangefinder with no problem.

As for the remote control, take a look at my demo:
http://www.societyofrobots.com/robotforum/index.php?topic=7106.msg57627#msg57627

And at the code here:

wow thats really kl, ill give it a go maybe tomorrow.
thanks

just my thoughts but you shouldn't base your projects on what you have lying around...
its cool if you have the parts but don't let what you have restrict you,
buying parts can only benefit you in the future...

jakx12 · « **Reply #15 on:** May 29, 2009, 03:29:17 AM »

oh yh i know, but i got another servo that is broken. But im only buying stuff for the arm as its pretty expensive for me.

SmAsH · « **Reply #16 on:** May 29, 2009, 03:53:50 AM »

hah, money is tight for all of us.
me being a student gets about $10us a week pocket money...
looking for a job right now...

jakx12 · « **Reply #17 on:** May 29, 2009, 05:15:10 AM »

yh, as a student i get about £20 a month which equates to about 30$ a month

. In london its really hard to get jobs, especially for kids. So i have already tried but i just cant find one

SmAsH · « **Reply #18 on:** May 29, 2009, 05:26:53 AM »

now that is one reason why i hate living in a big city,
i think mine has like 60, 000 people max.
try applying everywhere, i think you will find one eventually.

jakx12 · « **Reply #19 on:** May 29, 2009, 05:30:21 AM »

im 14 so i cant find one. Iv tried everywhere! Even like web design etc. My friend has a company called get-web.(www.get-web.co.uk). But he said if he has a job with php etc then he'd call me to help and pay me

. Thing is, he still hasnt called me

SmAsH · « **Reply #20 on:** May 29, 2009, 05:34:22 AM »

im 14 too...
you must have local fast food places that are looking for people...
i know that im shy and don't know how to apply but luckily target lets you apply online

jakx12 · « **Reply #21 on:** May 29, 2009, 05:35:49 AM »

There are fast food places, but there are age limits aswell. And as its the recession etc, they are firing not hiring lol.

SmAsH · « **Reply #22 on:** May 29, 2009, 07:46:08 AM »

lol, the age limit here is 14y9m to work but 13 and up with parents consent...
sorry to hear about the job $:-\$

jakx12 · « **Reply #23 on:** May 29, 2009, 07:55:59 AM »

meh, il try a balancing thing and tell you how it goes.
