P3AT is a 4-wheel drive all-terrain pioneer robot from ActivMedia Robotics, with a high payload. The turn is based in sliding. It affects the odometry data, mainly the estimate for the orientation.

P3AT is a full aluminum platform with a control panel in the upper side to access its microcontroller (Renesas SH2). Also, it has a RS-232 serial port to communicate with the server software. The microcontroller runs an ARCOS operating system for the low-control of the engines, the sensor data readings and the battery level. Renesas SH2 operates at 44 MHz and it presents 32KB of RAM memory and 128KB of flash memory.

Nemo Robot

The specification is as follows:

  • Dimensions: Length x Width x Height = 50 cm x 49 cm x 26 cm
  • Wheel: Diameter x Width = 22 cm x 7.5 cm
  • Weight: 14 kg
  • Payload: 40 kg
  • Maximum Drive Speed: 700 mm/s
  • Maximum Rotating Speed: 140 deg/s

In summary, the P3AT is equipped with:

  • Sick Laser Scanner LMS200
  • Power Cube PW70
  • Odometry sensor
  • PTZ Camera (Coming soon)

Sick Laser LMS200

It uses an infrared laser beam of class I (harmless for the human eye) to obtain distance accurate measurements fast. The beams are over 180ยบ and they are independent of the objects' reflectance.

PowerCube PW70

The PowerCube W70 wrist by AmtecRobotics is used to pitch the 2D laser sensor modifing the tilt angle and get a 3D operation range. It is also possible to vary the pan angle. It is supplied with 24 V and its is connected to the control device by a serial interface as RS232, CAN-bus, Prodfibus-DP. The strong and light design provides great speed (356/s for tilt and 248/s for pan)
