High-speed collision avoidance sensor and object detection sensor!

React faster and detect obstacles with greater assurance thanks to a fixed update rate of 600 readings per second! The small and lightweight design (from 9g) allows seamless integration in a variety of applications, while the fast and constant data stream provides reliable performance in a broad range of operating conditions. Unlike laser, we use LED technology. By opening up the Field of View, we detect obstacles within an area. For many applications, this produces a more reliable and stable data-stream compared to the pin-point of a laser beam.

TeraRanger Tower Evo is a solid-state LIDAR system with 4 or 8 detection zones monitored simultaneously at high speeds.

With zero moving parts, Tower Evo offers increased robustness and silent operation, while the compact and lightweight design makes it ideal for fast-moving and lightweight robotic applications, both on ground and airborne! Tower Evo’s active infrared Time-of-Flight sensors are eye safe in all conditions, giving you the freedom to place and use the system wherever needed.

coupled to the natural movement of the robot (both translations and rotations)

When mounted on a ground or airborne robot, the simultaneous data point acquisition of 4 or 8 axes at high speed, coupled to the natural movement of the robot (both translations and rotations), ensures the capture of features and data points around the robot, with similar output to the laser scanners typically used in SLAM operations.

Terabee welcomes collaboration from partners looking for innovation in sensing and intelligence for drone applications! Our technical expertise includes drone-optimized “indoor GPS” for GPS-denied environments, sensor fusion, algorithms, control system development, custom sensor design, sensor industrialization and integration into customer platforms.

TeraRanger sensors were born from a collaboration with CERN (European Center for Nuclear Research) in Geneva, Switzerland to fly drones in the 27km long tunnel of the Large Hadron Collider for fully autonomous inspection! Our background in that project along with our products and deep technical knowledge makes us ideally placed to assist with complex drone applications, with a particular focus on absolute and relative positioning, SLAM, navigation and robust anti-collision.

"Terabee proved to be a reliable and trusted partner in our technological development project in the context of UAV indoor positioning. We definitely received great experiences and value from our engagement with them." Dr. Benjamin Löhr, Head of Lufthansa Aerial Services.

The TeraRanger Inspection Drone Kit is used for drone pilot aid and utilizes the small, lightweight (8g) and high-performance TeraRanger One distance sensor/s (8g) and a small electronics board to interface to the live analogue video feed. Drone pilots benefit from fast distance-to-target data being streamed to their live video feed to assist with complex flights in close proximity to potential obstacles and hazards. 

A graphical user interface allows you to choose where on your screen to display the distance values and to set certain parameters. For example, threshold distances can be set so that, if you fly closer than your set distance on a given axis, the distance value will be shown in a highly visible ‘flashing mode’ to alert you to the potential hazard.

Two kits are available, one with a single sensor and the other with three sensors, but the solution can support up to 8 sensors, simultaneously monitoring different directions. The kit contains:

● Either 1 or 3 TeraRanger One Type B sensors ● 1 TeraRanger Distance OSD board ● Sensor to OSD cables (50cm long) ● Cables for power and data transfer

Want to monitor more axis? Simply add more TeraRanger Type B sensors to your order.

Field of View Advantage

An advantage of TeraRanger LED technology is that it enables the sensor to have a “Field of View” so that, rather than measuring distance based on a very small point of laser light, the sensor measures over an area. At a 1m distance, the area is approximately 3cm by 3cm. At 10m it is approximately 30cm by 30cm, increasing linearly with range. For many drone applications, this is a significant advantage, enabling you to detect small hazards that the laser may miss. It also provides a more appropriate and stable data stream when flying a drone over vegetation, close to trees or other irregular shaped objects that need to be detected at high speed.

The TeraRanger Hub kit is an obstacle avoidance sensor and makes it easy to connect multiple TerRanger sensors to a single power and data hub and to integrate the data stream to your control platform. This is great for times when you want sensors simultaneously monitoring multiple axes.The kit enables you to plug and play with up to eight distance sensors and obtain high-speed distance data from each sensor.

The Hub provides power to each sensor, synchronizes the sensors for cross-talk avoidance and streams an array of calibrated distance values in millimetres via USB or UART. Select from two to eight TeraRanger One sensors with your kit!

The kit contains: – 1 TeraRanger Hub – 2 TeraRanger One sensors (Type A) (additional sensors can be added at the time of purchase) – 2 Sensor to Hub cables (22cm) – Cables for power and data transfer

TeraRanger Multiflex is the modular & low-cost solution for simple obstacle avoidance on drones, indoors up to 2-meter range! It’s the ideal –and higher performance – alternative to ultrasound all in one convenient and easy to use kit. Each Multiflex kit includes up to eight plug-and-play sensor modules that can be connected to a flexible bus.

The kit makes it easy to create custom configurations and to place sensors on a drone exactly where needed for various anti-collision set-ups’. An array of calibrated distances is streamed in millimetres from the Multiflex Hub via I2C, UART or USB.

TeraRanger Multiflex is available in two versions; Multiflex and Multiflex PCB. Multiflex has dust and splash protection covers and offers the fastest refresh rates, while Multiflex PCB has longer range, up to 2.0m. See the specification sheet for further information on the two versions.

With zero moving parts, TeraRanger Tower is a silent & reliable alternative to rotating LiDAR scanners for navigation and obstacle avoidance. It combines 8 TeraRanger One sensors in a circular array and the TeraRanger Hub to create a lightweight, fast (up to 270 Hz), and eye-safe scanner. Calibrated distance data is streamed from a USB or UART port as an array of synchronized distances, in millimetres.

Two versions are available, one with eight TeraRanger One sensors (Tower 8), and the other with four TeraRanger One sensors (Tower 4). Tower 8 gives you more data points to work with, producing denser maps and providing more sensing coverage for collision avoidance. Tower 4 is a lower cost alternative offering the flexibility to place 4 sensors where needed, and the option of plugging in more sensors at a later date if required.

For many drone applications, this is a significant advantage, enabling you to detect small hazards that the laser may miss. It also provides a more appropriate and stable data stream when flying a drone over vegetation, close to trees or other irregular shaped objects that need to be detected at high speed.

TeraRanger Evo is the long range distance sensor of the TeraRanger family and is ideal for reliable altitude control, terrain following and anti-collision, both indoors and outdoors. Using LED Time-of-Flight technology (rather than lasers) the 9-gram distance sensor can measure distances up to a 60-meter range! In addition to its long-range capability, it has a modular two-part design, supporting a wide range of power, communication and connector options without additional cables.

Customization for embedded applications is also possible.

The small and lightweight Evo allows easy mounting on drones without hindering flight performance. Using a convenient 5V input, the sensor is calibrated and easy to use, streaming digital output in millimetres via *I2C/UART or USB.

A small, lightweight & high-performance single-point distance measurement sensor using infrared LED Time-of-Flight technology for indoor and outdoor conditions. The lightweight design (only 8g), high performance (up to 1000 readings per second), low power consumption and stable datastream make it perfect for reliable altitude control, precision landing, terrain following and anti-collision, both indoors and outdoors.

The sensor is calibrated and ‘plug and play’ simple to use, streaming digital output in millimetres via I2C* or UART.

*TeraRanger I2C accessory cable available.

For crosstalk avoidance in multiple drone environments two versions of the sensor are available, type A and type B, which can operate simultaneously without affecting each other’s reading. Sensors A and B performance are very similar. We prefer A for indoor environments and B for outdoor as the latter is more stable in direct sunlight.
