As with other RobotEye Vision system’s the 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 behaviours stabilization of the system aperture continues uninterrupted.
With the REV25-ST, Ocular Robotics has delivered a stabilized camera system unmatched in performance in its class. Key features particular to the REV25-ST are:
Not only is stabilization about three axes rare in a form factor comparable to the REV25-ST, the REV25-ST delivers stabilized motion about yaw, pitch and roll at the high levels of performance characteristic of RobotEye Vision systems.
Operate in a Global Coordinate Frame
When stabilization is active on the REV25-ST, pointing commands are issued as roll-pitch-yaw Tait-Bryan angles in a North-East-Down reference frame. The REV25-ST has ample motion bandwidth to simultaneously stabilize and execute complex behaviors such as, track, even multiple objects or build maps. The ability to issue the motion commands needed to execute these behaviours in the global coordinate frame and recover information about the current orientation of the system aperture in the same global frame is invaluable for users and application developers.
Bounded IMU Drift
The AHRS used in the REV25-ST uses Magnetometers and MEMS Accelerometers in addition to MEMS Gyroscopes. This additional information enables our stabilization system to bound drift in all three rotational axes, as compared to the 2-axis bounding possible with Gyro/Accelerometer systems, or the unbounded drift from a Gyro-only system.
Camera Choice Flexibility
As with the REV25 Vision system the REV25-ST also allows complete freedom to attach any C-mount camera to the REV25-ST that is needed for your application. Whether your camera is the size of a brick or a matchbox, 50 grams or 5 kilograms there is no difference in the pointing dynamics attainable with RobotEye Vision systems. Ocular Robotics is able to install a wide selection of cameras from the Allied Vision Technologies range or the user is free to install and use their own camera of choice.
