Introduction
The scope of this page is to document the Mini-PI robot.
Mini-PI stands off:
- Mini: The simplest robot: Miniskybot
- PI: Raspberry-PI: cheapest Linux PC
The intend is to build a robot, very simple, using 3D printer, and with the Raspeberry-PI as a main processor.
I will start writing here the steps i am following to do it. I have been so many years without building a robot, and now, i feel excited about it. During these years i have been following all Juan's publications, and i will take advantage of all of them: 3D printers, python, Skymega, ...
About me: I am living in California now, that is one of the reasons i am writing this in english, another, is because i would like to present this in my son's school. They knew about my background in robotics and they would like me to present something. They have a strong team in Lego Mindstorms... let's see what i can do!!
Raspberry-PI
The main webs of Raspberry PI are http://www.raspberrypi.org and http://elinux.org/R-Pi_Hub. The board was originally developed as an educational project, and has became very popular during 2012. I recommend to read this note from the authors.
I decided to use it because several reasons:
- It is cheap
- It is well documented
- It is broadly used
- It has an easy hardware
- It has a GPIO bus with (IO, I2C, SPI, UART), and of course USB, ETH, ...
- Supports Debian Linux
So, after having used a lot of embedded kits (TI DMVA2, DM368, Hi3516, Freescale, Versalogic, DM667, ...) i found this kit really interesting for building low cost robotic applications. It took me a while to find the right moment to start, but once i did it, i was surprised about how fast and easy was to set up everything.
I bought the Raspberry-PI here: http://www.alliedelec.com/images/products/mkt/pb/rasp/rasp.aspx
There are two models A and B. In my case i bought the B because i wanted it to have Ethernet on the board. Option A is not a bad idea, for example if you want to have Wifi then, instead of buying the model B that has the ETH, you can buy the model-A (cheaper) and a USB-Wifi-Dongle...
The first thing i did was to flash the SDcard. I followed the following links:
- http://www.raspberrypi.org/downloads
- http://downloads.raspberrypi.org/download.php?file=/images/raspbian/2013-02-09-wheezy-raspbian/2013-02-09-wheezy-raspbian.zip
