The robot should have:

  • a dimension of about 25cm of radius, 20 cm height
  • a speed of about 1 m/sec
  • omnidirectional movement (Kamro wheels)
  • sensors to avoid obstacles (sonars)
  • a camera that can be moved up and down (and eventually left and right)
  • wireless connection to a computer (Wi-fi)
  • Bluetooth connection
  • have power enough to move and transmit for at least 2 hours without recharging
  • Have the possibility to recharge autonomously

The robot should cost as less as possible


  • Select HW
 ** ST ARM HW (ask Martino Migliavacca <martino.migliavacca@gmail.com>, GUMSTIX (http://www.gumstix.org/), ARDUINO (http://www.freeduino.org/), other...)
 ** Engines (WWW.robot-Italy.com, http://www.jonathan.it/)
 ** batteries (above, or standard A, AA or AAA type)
 ** Camera (ST smart cameras, with Ethernet wired link)
 ** Sonar (already available (see ROBOWII2.0))
 ** Blue tooth and WI-FI
  • Design body (structure and appearance), sensor placement, eventual movements of the camera
  • Implement the robot
  • test the robot with a simple game (e.g. RoboWII2.0)

Motion Control

Motion control.JPG

Angle between V1 and X-axis is 30° Angle between V2 and X-axis is 150° Angle between V3 and X-axis is 270°

V1 = F3-F1 V2= F1-F2 V3= F2-F3

Vt= c1*V1 + c3*V3 (region 3) Vt= c1*V1 + c2*V2 (region 2) Vt= c2*V2 + c3*V3 (region 1)

If Vt is between V1 and V3 then region 3 V1 and V2 region 1 V2 and V3 region 2
