Our new sensor enables your AGV, AMR, or other application avoid collisions with all kinds of obstacles. Based on our proprietary 3D ultrasonic technology, our next-generation ECHO ONE DK operates on the principle of time-of-flight echolocation to deliver robust real-time data for 3D object detection and collision avoidance.

Why use 3D Ultrasonic Sensors?

Reliable detection of multiple objects

Is your AGV or AMR prone to collisions because your existing sensor solution does not reliably detect multiple objects or complex objects like forklift forks in 3D space?

Reduction of false-positive detections

Are you tired of false-positive detections ( = your sensor technology mistakenly detecting a non-existing object), which increases the downtime of your AGV?

Reduction of false-negative detections

Are you worried about false-negatives ( = your existing sensor technology not detecting an object at all), which could lead to costly and dangerous accidents?

6 Unique Benefits of the ECHO ONE

We know your pain and can help you increase your profitability and reduce costly accidents.

Simply scroll through our six unique advantages of 3D Ultrasonic sensing.

Functionality Easy-to-use Software for Application Setup

1. Improve your overall operational efficiency

Traditional 1D Time-of-Flight sensors can detect only the closest object relative to the sensor. Due to our unique hardware setup and advanced algorithms-based software technology, our sensor can detect multiple objects in 3D space in real-time. This reduces accidents, optimizes your factory workflow, and improves your operational efficiency.

Easy-to-use Software for Application Setup

2. Ease the hassle of set-up and integration

Our unique integration platform offers you great flexibility to evaluate the ECHO ONE DK in your individual application. It consists of a:

  • Software package, which include ROS, Toposens Sensor Library, Firmware Update Tool and Toposens 3D Visualizer
  • CAN communication interface
  • Separate interface adapter to connect the sensor to a PC

3. Reduce costly accidents by detecting even the most complex objects in 3D space

Most optical-based sensor solutions can struggle with detecting certain colours (such as black-coloured forklift forks) and have difficulties working under certain weather and lighting conditions (dark surroundings, fog or reflecting surfaces, for instance). Due to being sound-based, the ultrasonic sensor technology at the heart of ECHO ONE DK is typically tolerant to lighting and weather conditions. Thus, it can detect complex items such as the tip of a forklift fork, transparent surfaces or tiny objects lying in the path of your AGV. This reduces the occurance of potential accidents and ensures a smooth workflow.

4. Use your AGV safely in any environment

As the IP67 certification reflects, the ECHO ONE DK is robust to dirt, dust, and water. Also, lighting conditions or specific colors do not interfere with the sensor’s capabilities as our sensor operates with ultrasonic technology.

5. Safe costs by using just one sensor with enhanced perception abilities

The ECHO ONE DK is able to detect multiple objects in front and at the sides of it. This is achived through the sensor’s very large opening angle, boosting a horizontal and vertical Field-of-View (FoV) of up to 180° at ultra-short-range (from 200mm) and up to 110° at 3m (horizontal FoV).
Thus, one ECHO ONE DK sensor will be enough to cover the whole area in front of your AGV.

6. Improve AGV operational performance with a reduced blind zone

The ECHO ONE DK operates with a minimal blind zone, being able to detect objects from as close as 200mm. This takes robot safety to the next level and improves your AGV’s performance.
