Presentation Transcript

  1. Remote robot control using mobile devices • Andrey Litvinov • Evgenia Samochadina • Renat Valeev

  2. Remote control: target setting

  3. Input Data • Nokia Mobile phone • Lego Mindstorm NXT Robot Spike • LeJos Operating System • Java Development Tools • 3 brains & 6 hands

  4. Main parts of the work • Basic knowledge acquiring • Bluetooth connection • Robot application • Mobile phone application

  5. Using mobile phone we can manage: • Motor Control • Smooth • moving forward/ backward • turning left/right • Tail kick • Sensor Monitoring • Touch sensor • Sound sensor • Ultrasonic sensor

  6. How it works… • Prerequisite: pairing phone and NXT (code 1234) • Bluetooth library JSR82 (device discovery, connection) • Protocol: Send (2, 0, Data, Data) • Protocol: Receive (1, 0, Data)

  7. How it works… List of commands MOTOR_FORWARD = .. … MOTOR_B = .. MOTOR_C = .. … Send(MOTOR_FORWARD, MOTOR_B); Send(MOTOR_FORWARD, MOTOR_C);

  8. List of commands GET_SENSOR_TYPE = .. CMD_SUBSCRIBE_SENSOR = .. … TOUCH_SENSOR = .. … SENSOR_1 = .. How it works… Send(GET_SENSOR_TYPE) Send(TOUCH_SENSOR, No, No, No ) Send( CMD_SUBSCRIBE_SENSOR, SENSOR_1) Send(SENSOR_1, 1)

  9. What have been easy? • Construct a robot (because actually we didn’t do it) • Control sensors • Control motors What have been difficult? • All connected with Bluetooth • Pair devices • Investigate Bluetooth protocol of robot and the way it transmits the data

  10. Whatwehavelearnt? • Working with Bluetooth • Working with NXT robot • Using LeJos for NXT programming • Working with LeJos Bluetooth protocol • Working with sensors • Working with motors • Special features and details about LeJos • NXT robot is the best robot in the world!
