  1. 1. ROBOTICS BRASOV MEETUP 1404 SILVIU TURUGA
  2. 2. What is a robot? - a machine that is autonomous or semi-autonomous - can be programmed - usually contain at least one microcontroler - can take real-time decisions based on different sensors - can interact with other robots/equipments ! MORE INFO: HTTP://EN.WIKIPEDIA.ORG/WIKI/ROBOT
  3. 3. Building a robot Micro-controller / Development board Mechanical parts: chassis, wheels, tracks Sensors Patience
  4. 4. Development Boards Arduino - http://www.arduino.ccRaspberry Pi - http://www.raspberrypi.orgOthers, such as Orangutan SV-328p from Pololu
  5. 5. Other components Sensors Distance - IR, sonar Temperature Contact Accelerometers/Gyroscopes Mechanical parts
  6. 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.
  7. 7. How it works 1/2 rPi SV-328p Rx Tx Tx Rx M2M1 OS: RASPBIAN(Debian Wheezy) Python + Django pySerial package C + libPololu AVR
