Micro-controller / Development board
Mechanical parts: chassis, wheels, tracks
Sensors
Patience

4. Development Boards
Arduino - http://www.arduino.ccRaspberry Pi - http://www.raspberrypi.orgOthers, such as Orangutan SV-328p from Pololu

5. Other components
Sensors
Distance - IR, sonar
Temperature
Contact
Accelerometers/Gyroscopes
Mechanical parts

6. Practice project
rPI is hosting a Django server for an online shop
Each item can be found in one of the 3 warehouses
available
When a customer is ordering something, rPi is
sending a command through serial to SV-328p.
SV-328p controls the motors of the robot.
