A robot that flies like a bird ( Not Mine)

 So today I got this link from my boss because he knows i'm into robotics as a hobby, I have seen flying robots before but this is scary when i think about the military implications. Carzy stuff. If you have seen it before forgive me but i figured i had to share

Can't get my HXT900 servo to move

Hi,

Trying to get my HXT900 to work on my test board but it just screams. I'm using a PICAXE 08M pins 0,1,2. there is a jumper that i set to downlaod and then to use as low for servo. orange cable to pin 0, red cable to pin1 and brown cable to pin2 The following is my code. Anyone out there ever came across this . Note I had it working once on my 18M

 

init: 

low 0

high 1

Homemade : IR Object Detection with a range greater than 5cm (target is 10cm)

Has anyone successfully implemented object detection using IR for a range greater than 5cm. I am building a robot project from scratch with the personal challenge of making all parts homemade. The brainboard and motor controller were succesfully built but now that i want to do object detection using IR (without getting the sharpe module) I have issues with ambient lighting and range.

The Making of CircumPic

What follows represents my aim at documenting the creation of my yet to be named robot using a picaxe18x for brain and a l293d for motor control. Hopefully at the end i should be able to control the robot via IR and also have the ability to flip into auto mode. Too much to expect from an 18X ? We'll see.

Using Interrupts in PICAXE 08M to change led lighting routines

marlonlevy's picture

I was in the process of completing this carzy project of mine, where i had a single picaxe 08m chip driving four leds (green, red and amber). Its intended to give my four year old daughter something fun to look at. However I am a bit stuck as in teh code I can only get the interrupt to fire once via teh simulator. 

Any help will be appreciated.

 

symbol green_led = 0

symbol yellow_led = 1

symbol red_led = 2

Why does my motors stop spinning after awhile

marlonlevy's picture

 

Hi all,

I am on my second (well third if you count my incomplete herbie bot) and i have completed proto work on my project board with hook up wires. My basic code thru the PICAXE 18X is to keep pin 7 and 6 HIGH while 5 and 4 LOW as triggers to the inputs of a L293D motor driver. What I find is that for the most part the motors spin for a while and then stop for no reason.

 

My L293D are directly connected to the motors with no caps in place. Could the missing CAPS be the reason my my motors halt after awhile ?  

 

 

Downloading to a picaxe not as consistent as i would like

 Has anyone every encountered an issue where your connections are correct for the picaxe download circuit but for some random reason the Programme Editor only detects your chip sometimes with no alteration to the setup it detcts it one minute and not the next. once it does the program works.

code now loaded by chance:

 symbol green_led = 4

symbol yellow_led = 1

symbol red_led = 2

symbol wait_green = 30000

symbol wait_yellow = 500

symbol wait_red = 30000

July 5, 2009

It took me a great deal of time to decide what my next project would be but finally after weeks or browsing this site I opted to doing yet another BEAM project before launching head first into the relams of programmable robots using such chips as the ardunio. I must admit thought it was kind of tempting to skip minor projects to launch a big one. ANyways enough of my rambling.
