My First Segway
@ December 4, 2010
- Actuators / output devices: two opel vectra wiper motors
- Control method: XBee, WiFi, through my phone via TouchOSC
- CPU: Arduino Duemilanove
- Operating system: Mac OSX
- Power source: 4Ah 12V battery
- Programming language: Processing, Arduino
- Sensors / input devices: Touchscreen OSC messages from Android phone, maybe more in future
- Target environment: indoor
This is my first arduino project ever. I at first wanted to create a wireless car with a camera mount so that i can drive around the building. I started at the car scrap where I found two wiper motors for 10 EUR total (!). The man told me these things were incredibly strong so I figured why not carry me around then? The idea for a segway rose.
btw: the video is still an old one, i will upload a newer one asap
Thanks to people from the circuits-online forum I soldered my own motor control whose cables frequently melted - a lot - I finally got it working without any heat issues - thanks to the MOSFETs and thick enough wires - I first used ordinary transistors, but they got pretty warm:
After the wiring has been made thicker, it finally worked. here's a video of me standing on it and controlling it using the WASD-keys on my macbook in Processing: http://www.facebook.com/v/1675245211184
To control it, I use my android phone with TouchOSC (just released - 1 dec 2010). It sends the current x,y coordinate of my finger on the touchscreen to my macbook with Processing. This sends a signal through the xbees to the arduino in my segway.
I have a new video of me (standing on it riding it) still in the want-to-edit/upload-queue, so pls wait for more!
update:
I now hooked up an AXIS ip camera and a wifi router. now im able to watch the cam-feed on my iphone and control it with my android phone!!

update: i now mounted an
update: i now mounted an Axis 205 IP-camera and a linksys WiFi Router which both work on the 12V battery. the IP cam needed a voltage regulator (LM7805) in between the cam and the battery (for the 5V .5 A power supply).
Now I can watch the webcam feed on my iPod Touch and control it on my Android HTC Legend xD

Can you post source code,
Can you post source code, please?
Thanks! :)

source code? for what?
source code? for what? arduino? processing?
im not gonna put my *lifework* here out in the public hehe ;)
just what would you like te know, for example?

I was curious to know what
I was curious to know what kind of control system you were controlling the motors, whether it was PID or not.

for each motor, i use two relays to go back/forward, and a MOSFET to control speed using PWM. Each relay is controlled by a transistor, which is connected to an arduino port.
here's a picture:

You could always post it
You could always post it under "something else", and it is something else! Very cool idea!

motors...
From where did you got those motors are so neat.
Can buy 2 of those somewhere on the web?

i went to the local car
i went to the local car demolition place 'autosloop in Dutch' and there i got two wiper motors for 10 EUR ( ± $15)..Opel is a european brand, i dont think they have it there in the US though.... here's a good site with a lot info:

I live in Greece which is in europe but I dont know where to find such a place.

junkyard
you dont have a junkyard in Greece???
junkyard = μάντρα according to Google Translate...
