  • 23rd May - Read the hardware manual of Firebird V robot thoroughly

  • 24th-25th May - Started working with raspberry pi.

  1. Installed Raspbian OS in the raspberry pi using the preformatted SD card with the help of Win32Discimager.
  2. Made required settings and enabled SSH in raspberry pi using an ethernet cable.
  3. Established connection between laptop and raspberry pi using Wifi dongle and hotspot of laptop via connectifier desktop app.Hence the raspberry pi could be accessed through the laptop without the need of external monitor,keyboard, mouse and other accessories.

  • 26th May - Tried some basic buzzer, led programs,understood and tested the main board pins and their functionalities, updated the OS of raspberry pi, installed some required softwares and libraries.

  • 27th-29th May - Interfaced the ADC IC (MCP3008) with raspberry pi and tested the analog values given out by all the IR proximity and white line sensors on Firebird V. Also wrote and tested code to calculate the distance of the objects from the sharp IR sensors.This ADC IC communicates with Rpi on SPI serial communication protocol, hence SPI was enabled in RPi.

  • 30th May - LCD of the Firebird V robot was interfaced with Rpi and the code was written and tested.

  • 31st May - Since the Rpi has very few GPIO pins, in order to use all the accessories of Firbird V like sensors, motors, communication ports, LCD etc we need more pins, hence port expander IC(MCP23017) was interfaced with Rpi and previously written codes were tested with the new GPIO ports.

  • 1st June - Interfaced motor and motor drivers on the main board with Rpi and codes were written to test its functionality. Also, wheel encoders were tested and motors were controlled using the feedback from these encoders.

  • 2nd June - Interfaced the Xbee wireless communication module and tested its fuctionality. The Tx and Rx ports of which were available at the UART0 pins in the main board of Firebird V robot.

  • 3rd June - Rpi powering circuit was developed and tested. Also, the battery voltage indicating circuit using the bar graph LEDs was developed and tested.

  • 5th June - The documentation of the work done till date and PPT with fritzing diagrams to show the circuit connections were made.
