TeraRanger Duo

TeraRanger Duo by Terabee: demolish all obstacles

Prepare your mobile robot for a multitude of adventures, and for navigating even hostile terrain. Realising you may one day need a distance sensor capable of detecting the smallest of obstacles on any soil or terrain, Terabee has designed a device combining both a ToF distance sensor AND an ultrasonic distance sensor.

The TeraRanger Duo collects the two types of information generated by these different sensors to calculate an obstacle’s proximity.

The two technologies combined offer excellent detection precision, regardless of the terrain on which your creation has adventured; whether navigating a carpet, a glass surface or even a small body of water, nothing will escape its expert eye.

Time-of-flight technology offers an excellent update rate, a long range and record accuracy, while ultrasonic technology gives a wider detection angle. Combine the two and you get a highly reliable distance sensor in a compact, lightweight format.

TeraRanger Duo: a highly customisable distance sensor

The TeraRanger Duo adapts to all kinds of communication protocols, including UART, SPI and I/O. Plus you can add a USB plug-and-play connection by using the TeraRanger USB adapter (sold separately). This ToF and sonar distance sensor opens up all ROS programming possibilities, and can also connect to SLAM software for those wanting to embark on real-time 3D mapping.

In addition, for the true enthusiasts among you, the TeraRanger Duo processor has sufficient memory space for implementing your own distance calculation algorithm.

Technical specifications of the ToF and sonar distance sensor

• Infrared ToF and ultrasound technology
• Range: 14 m for the ToF sensor, 7.5 m for the ultrasonic sensor
• Update rate: 1000 Hz in fast mode and up to 600 Hz in precision mode for the ToF sensor, up to 15 Hz for the ultrasonic sensor (1 Hz in default mode)
• Resolution: 0.5 cm for the ToF sensor, 1 cm for the ultrasonic sensor
• Accuracy: +/-4 cm in precision mode (ToF)
• Field of view: 3° (ToF), 5–10° (ultrasonic)
• Supply voltage: 12 Vdc recommended, 10–20 Vdc accepted
• Supply current: 50 mA average (110 mA peak @ 12V)
• By default, the sensor processes 2 distance values at the same time (one obtained by the ToF sensor, the other by the ultrasonic sensor), which you can integrate into your own algorithm
• Dimensions: 53 x 44 x 25 mm
• Weight: 16 g
• Possible interfaces:
• UART interface, +5V, up to 115200,8,N,1 (the sensor is shipped with factory settings)
• SPI interface (shared with JTAG), 1 CS line, +5V
• 2 user I/O lines, +5V for PWM connection, interrupts, LEDs, etc.
• 15 pin DF13 connector (open-ended cable provided)
