This is my first robot project.
I am an electronics and computer systems engineer with over 20 years experience.
When I was looking to do this in the past the size and cost of the technology was too big. Last year I saw a NOVA program on drones and decided that this can be done on a reasonable budget.
This is my R1D1 project (Rev1 Dorid1). I started building this last December but had an issues with the motors I used (old electric car seat motors and gears) the motors did not have enough torque and one had a slightly differing gear ratio. I did however construct the basic platform (all aluminum) and the basic software for driving the motors (Arduino), and on the Raspberry pi I have a web page interface, Wifi, and communication with the Arduino over the USB using vertical serial ports.
Then summer (no time for robots)
This December I started again with 2 new motors I ordered off ebay. Drive problems solved. At this time I have upgraded to the Arduino Mega and added ultrasonic sensors. Next is GPS compass and Pi camera. Then much programming as I want this to be an autonomous robot.
