Linear Actuator suits remotely operated applications.

Press Release Summary:



Tuned and configured for 1-2 msec pulse RC interface, remotely operated RO-Bug integrates 12 or 24 Vdc servo motor with 12 or 24 Vdc amp. Bug linear actuator is available in 2, 4, and 8 in. stroke lengths with Vantec amp. Servo motor is connected to ball or Acme lead screw driven by Kevlar-T reinforced drive belt, which provides for reduction ratios of 1-5:1 and quiet operation. Linear potentiometer provides feedback for closed loop operation with accuracy to ±0.005 in.

Remotely Operated Linear Actuator for ROVs and UAVs Can Also Meet The DARPA Challenge



Mattituck, NY -- A new, high quality, compact, "RO-Bug" remotely operated linear actuator system integrates a 12 or 24 VDC servo motor with a 12 or 24 VDC amplifier for RO (Remotely Operated) applications. Each "RO-Bug" remotely operated linear actuator and amplifier system is tuned and configured for a standard 1 to 2 milliseconds pulse RC (Radio Controlled) interface. Possible applications include: Remotely operated industrial, law enforcement, and entertainment robots, rudder, aileron, throttle, and camera controls for UAV (Unmanned Aerial Vehicle), throttle, steering, braking, and shift controls for ROV (Remotely Operated Vehicle), and radio controlled "Battlebots." The 12 or 24 VDC system is also ideal for vehicles entered in the DARPA Challenge.

The American made, "RO-Bug" remotely operated linear actuator system integrates Ultra Motion's Bug linear actuator that is available in three stroke lengths of 2 in, 4 in. and 8 in. with a Vantec amplifier. Engineered to fit a broad range of applications, the lightweight Bug linear actuator is available with a choice of 12 and 24 VDC servo motors. The servo motor is connected to a ball or Acme lead screw that is driven by a Kevlar-T reinforced drive belt which provides for reduction ratios of 1:1, 2:1, 3:1, 4:1, and 5:1, and quiet operation. A linear potentiometer provides feedback for closed loop operation with an accuracy to ±0.005 inch over the operating temperature range of -32°F to +130°F at speeds from .001 to 20 in/sec.

The lightweight "RO-Bug" remotely operated linear actuator is permanently lubricated for maintenance-free life. A variety of end connections and trunnion mounts provide for easy integration into an application. The "RO-Bug" remotely operated linear actuator system can also be interfaced with a microcontroller for use on an umbilical cord or operated by an on-board computer. It is ideal for applications such as the DARPA Grand Challenge (http://www.darpa.mil/grandchallenge). Ultra Motion linear actuators are on several of the vehicles entered in the DARPA Grand Challenge '05.

Ultra Motion is a manufacturer and supplier of high precision electromechanical mini-linear actuators and matching controllers. Generating high forces, they are the ideal alternative to hydraulic and pneumatic systems. Typically, these clean and quiet, high performance mini-linear actuators are selected for low to moderate power applications when high precision and reliability are important requirements. Using state-of-the-art materials, they are lightweight and very cost effective.
