RDrive servo by Rozum Robotics is an all-in-one robotic joint. RDrive servomotor unites in a single housing all the main elements: an encoder, a controller, a harmonic gear and an AC brushless motor. Since the controller is integrated into the robotic actuator, the RDrive is a DC servomotor with a brushless AC core.
Service life of our servo motors is 35,000 hours. Rozum Robotics also provides a 1-YEAR WARRANTY. Our online support team is eager to help you whenever needed. Detailed video instructions and technical documentation are provided. Average servomotor lead-time 2-8 weeks. A network of international dealers and distributors for local support is available.
The first RDrive servo motor was created to drive Rozum Robotics collaborative robot that we designed and built completely in house. We were disappointed with the quality of cheap Asian robotic joints and were unwilling to pay for expensive customization in Europe. The factors motivated us to take it upon ourselves to design and create our own robotic actuator.
Most robotic joints manufacturers produce a housed brushless robotic actuator coupled with an encoder. They call it a servomotor. Powered by DC current, the servomotor is controlled with the help of an external servo controller kit (sometimes called robotic servo drive or robotic actuator). In case you need a gear motor kit, you connect a gearhead to the servomotor. The overall design is whatever but not a compact servo motor in this case.

Servobox unit is offered as an option to RDrive servos
Boasting compactness and precise positioning capability, servo actuators are employed in a variety of tasks in robotics. The engines move robot joints, operate work tools, or rotate wheels in self-propelling mechanisms. Products driven with the motor type vary from hobby models to giant industrial robots.
Servos are quick and easy to embed into a robot body. Using micro or nano modifications, inventors create robotic hands with dexterity of movements close to a human limb. Multiple servos can be connected on the same power chain, allowing varied and flexible robot configurations.
Known for great controllability, servos cope perfectly well with steering unmanned aerial vehicles, such as drones. The flying devices are designed as multi-propeller systems, where each propeller needs a drive and the total of drives should be able to work in sync.
With high torque output, servo motors provide required driving power—and more. Small dimensions of the drives allow their smooth integration into drones of various sizes. Availability of motion feedback and highly responsive control enable accurate navigation—from launching to landing.
In the domain, servo motor applications cover various machinery: filling and packaging, metal and wood cutting, trimming, as well as CNC and textile handling machines. Servomechanisms provide such valuable benefits as simultaneous control over multiple work axes and ease of integration, including into enterprise management systems.
Feedback allows to detect abnormal moves and ensure strict compliance with command input. Turn, cut, trim, and other processing operations can be performed with consistency and uniformity. Servo motors are associated with reduced maintenance costs and remarkable accuracy due to eliminated mechanics, such as backshafts, pulleys, etc.
In these systems, servos communicate with a specialized software that calculates coordinates for a panel to soak up sunlight or an antenna to receive a signal. The software commands to servos to move, while also processing feedback from the drives.
In this way, servos are able to provide ultra-accurate angular displacement to follow the sun or signal as required. Closed-loop governance and high holding torque make it possible to retain positions as long as necessary.
