Directed Perception, Inc., a manufacturer of products for the control and positioning of sensors, has now made availability their PTU-D48 family of computer controlled pan-tilt units. These units are designed for high speed, accurate positioning of cameras, thermal images, lasers, antennas, and other payloads up to 15 lbs in weight. The rugged and compact design has flexible mounting options for single or multiple payloads and is suitable for fixed and mobile applications (air, ground, sea) in industrial and military markets. The units are now shipping to customers worldwide for use The PTU-D48 delivers this solution for applications such as: tower mounted surveillance cameras, UAV camera systems, police and military ground vehicles, antenna tracking systems, border and perimeter surveillance, military force protection systems, night-vision applications, and more. The integrated design of the PTU-D48 provides a complete turn-key positioning solution for fast, accurate, dynamic, computer-controlled positioning of pan and tilt through a wide range of motion. Sensor and communications systems designers can save months of product development time by using the PTU-D48 as a complete, drop-in positioning solution. The patent-pending mechanical design uses worm gear design for superior dynamics and rigidity – there are no belts or pulleys. Specific performance features include payload capacities of 15 lbs (side mount) and 10 lbs (top mount) — fully controllable pan and tilt speeds ranging from below 0.006°/second to 100°/second — +/- 0.006° positioning resolution in pan axis — +/-220° pan range with internal payload wiring (option). The PTU-D48 includes a fully-integrated controller with digital commands for fine-grained control of speed, acceleration, position limits, and power modes. The unit can be commanded in terms of either position or velocity and allows on-the-fly command changes to support dynamic tracking applications. Both RS-232 and RS-485 interfaces are built-in and an Ethernet option is available. Control software interfaces available include a LabView driver and a C source-code API for use with embedded or desktop CPUs.
