The future of 3D vision is on-arm

Achieving human-like vision and manipulation capabilities is somewhat a holy grail for robotic System Integrators. It involves designing a self-contained robot system combining speed, image quality, simplicity, robustness, and cost. Attaching the 3D camera directly onto the robot arm unlocks a more flexible and effective solution since the 3D camera operates in its optimal space regardless of the working volume and robot reach.
Until today, 3D depth sensors have either had insufficient 3D image quality, been too slow, too bulky, or too heavy. Your typical 3D sensor has also not been robust enough to withstand the mechanical impact of on-arm robotics.
Finally, these challenges are solved. We designed the industrial Zivid Two 3D color camera explicitly to provide consistent, high-quality point clouds from a robot's arm. Learn more about the benefits of on-arm robot-mounted 3D machine vision cameras in our eBook.

Always optimal 3D image quality

On-arm mounting allows the Zivid Two 3D camera to operate at its optimal distance for every capture, even as you empty a bin. Object detection algorithms will always process the highest quality 3D data, with consistent resolution, color representation, accuracy, and noise performance.


Always empty the bin

By elevating the robot's flexibility with an on-arm Zivid Two 3D camera, you enable the system to view the scene and objects from multiple angles and positions, avoiding blind spots, occlusion, and point cloud artifacts (e.g. from reflections and highlights). On-arm 3D is the efficient way to reduce system cost and the number of sensors needed to empty bins successfully.

On arm robot 3D camera uses robot reach

Use the robot's reach

An on-arm 3D camera can always see whatever the robot arm can reach. This fact makes on-arm 3D solutions ideal for applications with multiple work stations, large surfaces, pallets, put walls, and flow racks. It also adds flexibility in mobile manipulator configurations.

Weighing <1000 g and with a small footprint, Zivid Two provides HD point clouds without interfering with payload or maneuverability.


Total cost and maintenance

For large scanning areas and robot cells that serve multiple locations, on-arm 3D vision minimizes the total cost of ownership by reducing the number of components that need to be installed, calibrated, maintained, and repaired.

The Zivid SDK and calibration board enable automatic and trouble-free in-field camera correction and 3D hand-eye calibration.

Whether it’s a low-level machine tending, pick-and-place, or visual inspection task, KoCo has to offer a solution that is not just more reliable and more productive than a human operator, but one which is infinitely adaptable as well. Only then will it make economic sense for the SME user. Happily, our experience using the Zivid Two camera so far is that this will certainly be the case.

Overcoming on-arm 3D camera barriers

Capture speed makes a difference.

One of the main concerns for on-arm 3D vision adoption is the impact capture speed has on duty cycle or system throughput. For each 3D capture, the robot cell must perform a "stop-capture-move" sequence. Improvements in object picking algorithms increase the picks per point cloud (3D image).

The industrial Zivid Two 3D camera captures HD point clouds from as little as 100 ms and is designed to withstand prolonged robotic acceleration/deceleration.

Robustness to handling and robot movement incidents.

All 3D vision systems are affected by environmental impacts like vibration, shock, and temperature changes. It is an under-communicated topic among vendors in the machine vision industry. A key design consideration for us was to address these factors and meet the requirements for on-arm robot mounting.

Therefore, the Zivid Two 3D camera is engineered and built from the ground up to excel under the harshest working conditions. All component in the vision system has been scrutinized, examined, and validated for stability and performance during years of development and design. Every 3D camera is then individually hardened and temperature calibrated, tested, and verified as part of the production process.
