Hello everybody,
I am a 20 year old student from the netherlands and I wanted to show off my project xD
so here I go

I will include a .pdf file for the ones who want to read this thing
copyright myself blah
ANNR.pdf
read after the reading the .pdf
Anyway I have decided to use a Arduino because this is a good platform for connecting the sensors and actuators with my Macbook Pro

So far I haven't got a lot, so if any of you have any thoughts, please share

:slight_smile:

I think neural nets are fairly memory-hungry - the Arduino may not be the best platform for anything but the very simplest of nets.

3

I use the arduino for the communications from the sensors to the Mac
The neural net will be hosted on a 2.66 GHz Macbook Pro with 4 gigs of ram.

So now all I need to do is make a connection between the Neural Net code and the Sensors and actuators :slight_smile:

thats where the Arduino steps in

Question,
How can I send commands to my laptop via usb and vice versa?

My Idea is to make a programm wich can control the sensors and actuators on the arduino..

stuff like.... setWheelA(speed, Direction);

and to read: readGyro();

Anyways, is this possible and if so, how.

This is the way I picture it..

I just ordered some parts

1x Arduino Mega
1x Memsic Dual-Axis
1x Gyro-module met MLX90609-R2
4x Ping))) Ultrasonic Sensor

3x R130-8CM-POLY-ROLLER OMNIWHEELS URL

I will begin drawing the platform this weekend, I have some sketches lying arround.

The idea is to put my laptop on top of this platform like this:

Lots of holonomic motion robots on the web - looks fun!

Yeah it is!
I made one before at Philips.
It was a Lego Mindstorms mudule wich wqas programmed with JAVA

I even made a bluetooth remote on my laptop

oh the fun we had xD

Edit:
If you read the .pdf file (1st post)
Is it readable for you guys?

Is it readable for you guys?

Ja hoor. Prima :wink:

How can I send commands to my laptop via usb and vice versa?

Lots of possibilities there:

  • serial communication using the USB connection. There are various libraries for this. Check the Playground.
  • I2C
  • wireless (RF @ 433 MHz, XBee, Bluetooth)

I think the final choice depends on a number of criteria, for example: how mobile you want the robot to be (i.e.: tethered to a computer or not), how reliable the communication between the robot and its hub should be (tethered is more reliable than 433 MHz, XBee is more reliable than RF @ 433 MHz), how much money you can afford to spend (BT is expensive).
Good luck, have fun & keep us posted of the results :wink:

Thanks man!
Kudos :smiley:
