Ocular Robotics REV25-ST

The RobotEye REV25-ST Vision-Stabilized is a 3-axis high performance stabilized vision system combining the REV25’s unprecedented motion bandwidth with an extremely low latency stabilization control loop. RobotEye Stabilized Vision systems are conceptually similar to conventional stabilized 3-axis stabilized gimbals systems in that they both affect the stabilized pointing of cameras about three axes, but that is where the similarity ends.

RobotEye Vision systems deliver groundbreaking capabilities in camera pointing with dramatic implications for many existing directable camera applications while also enabling new applications not previously possible. The REV25-ST couples the unique ability of RobotEye Vision system’s to steer the view of cameras at incredible speed and precision with extremely low latency firmware level stabilization that operates independently of motion commanded by the host.

As with other RobotEye Vision system’s REV25-ST system aperture can be controlled in a variety of ways to accomplish a wide range of tasks. The REV25-ST allows stabilization to be enabled or disabled as required during operation. Stabilization operates in firmware in a layer underneath highly dynamic motion commanded by the host through the RobotEye API. Due to the extreme stabilization bandwidth delivered by the REV25-ST, regardless of demands placed on the system by higher level behaviors stabilization of the system aperture continues uninterrupted.

Features

Robustness
The RobotEye REV25-ST Vision-Stabilised has been designed to operate in the harshest environments. RobotEye systems have a natural immunity to shock and vibration transmitted through the platform to which they are attached making them ideal for extended service on the ground, surface and air vehicles and other mobile equipment. This is achieved because the moving components in RobotEye systems are lightweight and supported at their periphery. In contrast to pan-tilt and gimbals systems have relatively large masses supported on shafts which under shock and vibration drive large forces back through the drive train shortening their serviceable lifetime. Other factors contributing to the reliability of the REV25-ST include:

  • The absence of any slip rings in the system which is due to the fact that all electronics including the camera remain completely stationary during operation eliminating the need to pass electrical signals through rotating joints.
  • The camera, motors and all electronics are located below the blue mounting flange as seen in the image on the adjacent page in a single enclosure or internal to the platform on which the REV25 is mounted simplifying environmental protection.

Imaging Options
A feature of the REV25-ST, when compared to gimballed camera systems, is the freedom to use any C-mount camera of your choice. The REV25-ST is offered with an option for wide or narrow field optics which enable the user to select the optical arrangement that best suits their chosen camera and their application.


System Customization
Supply to OEM’s and integrators is an important part of the Ocular Robotics business and as such customization of our standard offering to meet the needs of particular applications or operating environments is central to our operations. Whether it is tailoring for operation in a particular service environment, enhancing performance specifications, altering the optical path characteristics or a complete ground-up design for a particular application, all of these things can be achieved while retaining the trademark dynamic performance and other benefits of the RobotEye technology.
