When infrared Time-of-Flight meets water!

Time-of-Flight meets water

Time-of-Flight meet waterTime-of-Flight meets water! What happens when a TeraRanger One infrared Time-of-Flight distance sensor is pointed at water? Does it see the water and return reliable distance readings, or does all hell break loose?

Performance over water is something we are often asked about, so we did some testing, in the lab and out on the choppy waters of Lake Geneva, Switzerland. See what happened and learn whether TeraRanger distance sensors could be the solution you are looking for. Our sensors are small, lightweight (TeraRanger One is just 8g) and have update rates as high as 1000 readings per second!

Drone object avoidance with TeraRanger Tower

Drone anti collision

This short video shows a Proof of Concept (PoC) of how TeraRanger Tower can be used on a drone to detect a wall.

You can use a single TeraRanger One sensor for front sensor object avoidance or, as in this PoC, up to eight sensors for perimeter coverage. This is plug and play with APM (from version 3.5 onwards) and is compatible with other Pixhawk-compatible flight controllers. We look forward to the developer community building on this PoC and further enhancing the code.

If you wish to collaborate with us, or if you require a robust solution for drone object avoidance, drone collision warning and drone anti collision, please contact us. We will be happy to explore collaboration and project opportunities with you.

Please note, this has been created in good faith for the open source community and has not been tested in a wide range of conditions. Please conduct your own testing and use at your own risk.

TeraRanger One aids vision-based drone intelligence

TeraRanger One is being put through its paces by a team from Prague Technical University as they compete in one of the world’s leading robotics events; the Mohamed Bin Zayed International Robotics (MBZIR) Competition in March, 2017. The team of engineers has chosen the TeraRanger One sensor to compliment their vision-based systems in the Unmanned Aerial Vehicle challenges, helping them to perform tasks without human interaction.The prestigious MBZIR competition, which take places in Abu-Dhabi, gathers leading robotic research institutions from all around the world. It is intended to demonstrate the current state of the art in robotics in terms of science and technological accomplishments, as well as inspire future developments in robotics. The total prize pool is USD 5 million.The video demonstrates preparations by the Prague team and shows two of the UAV challenges they must complete. The first is to land a drone on the roof of a moving vehicle, fully autonomously and without pilot intervention! The second requires a team of drones to perform cooperative object recognition, collection and delivery. In both cases TeraRanger One sensors provide the drones’ vision-based systems with fast and precise distance-to-target readings, allowing them to determine the depth and scale of the vision-based data.

For the MBZIR competition, the Prague Technical University team collaborates with partners from Lincoln University and Pennsylvania University. Terabee wishes to thank Prague Technical University for allowing us to re-use and edit their original video and images and wish the teams success in the upcoming tournament.

Detecting glass surfaces with infrared Time-of-Flight

Detect glass surfaces with infrared Time-of-Flight

We often get asked whether our infrared Time-of-Flight distance sensors can detect glass and other transparent surfaces. And to many people’s surprise, the answer is “yes”. Clearly, there are some caveats, but you can read about those in this short white paper.

And if you need a fully redundant distance sensing solution, we have that covered too. TeraRanger Duo combines infrared Time-of-Flight with ultrasound for reliable surface detection in challenging
environments.

TeraRanger One helps ensure vineyard health with drone-based solution

drone vineyard health

Terabee is proud to support Chouette on their quest to keep every vineyard healthy! Thanks to their drone vineyard health monitoring solution, it is possible to prevent the spread of diseases that could potentially ruin hectares of vines and months of work.

To achieve this, they use TeraRanger One as a precision altimeter. Compared to laser-based systems with a very narrowfield of view, the TeraRanger solution provides a much smoother and more stable relative altitude as the drone alternates between flight over the ground and over the vines. Smoother flight improves the data acquisition process whilst also contributing to longer flight autonomy. This, combined with TeraRanger One’s low weight (just 8g) and low power consumption is helping the team at Chouette to achieve one hour flight times!

 

The Chouette team has produced this very nice video showing their platform in action and the services they provide ensuring vineyard health using drones.

TeraRanger Plug and Play sensor arrays

TeraRanger Tower enabling robotic collision avoidance and autonomous navigation

Fantastic video of a Kobuki traveling in a maze and performing robotic localization, robotic collision avoidance and robotic navigation with the non-rotating multi-axis 2D scanner TeraRanger Tower.  The robot recognizes the environment and navigates into it with a simple “click and go”.  The on-board software automatically highlights in blue proximity obstacles and, very importantly, if a new obstacle enters the scene the robot avoids it and create its own alternative path to goal.

TeraRanger Tower is a simultaneous multi-axis scanner for SLAM and collision avoidance capable of replacing traditional laser lidar scanners in some applications.

It is totally silent and has zero moving parts, resulting in greater efficiency and reliability. It combines 8 TeraRanger One sensors and the TeraRanger Hub to create a lightweight, fully eye-safe scanner for SLAM (Simultaneous Localization and Mapping) and collision avoidance on fast-moving ground and airborne robots. Calibrated distance data is streamed from a USB or UART port as an array of synchronized distances, in millimetres.

Drone automatic re-initialization and failure recovery system

drone failure recovery system

Professor Davide Scaramuzza and his team from the robotics perception group of the University of Zurich have developed a state-of-the-art re-initialization and failure recovery system for drones.
A TeraRanger One was used as a high-performance altimeter, without which the experiment would not have been possible.

Hexapod spider robot performs anti-collision and SLAM with TeraRanger distance sensors

slam-navigation

Fantastic video of an hexapod travelling in an apartment.  The robot recognizes the environment and navigates into it with a simple “click and go”.  The on-board software automatically highlights in blue proximity obstacles and, very importantly, if a new obstacles enters the scene the robot avoids it and create its own alternative path to goal.  Thanks to our partner Rhoeby Dynamics for the demo.

CES 2015: TeraRanger One distance sensor at Intel keynote speech

precision altimeter

The TeraRanger One enabled AscTec drones with perfect stability when flying over a sound absorbing carpet during Intel’s keynote speech at the CES 2015.   Brian Krzanich, the CEO of Intel, even mentions the ability of the drone to move smoothly “up and down” to avoid obstacles – this was made possible with our TeraRanger One precision altimeter (beta version).
