Redundant Servos for Increased Safety
XPONENTIAL Europe 2026 in Düsseldorf also serves as an important platform for suppliers of servos and control electronics. Numerous companies will be presenting their latest developments there, including well-known names such as KST, MKS, Volz, and Hitec.
Special attention is being paid to Hitec’s innovations. The company is introducing servos with an integrated feedback channel that enables precise monitoring of key parameters. These include the exact position, power consumption, and temperature of the servo. This data is crucial for optimized system control and predictive maintenance in unmanned systems. The integration of a feedback channel enables more detailed telemetry, leading to improved control and the ability to implement intelligent maintenance strategies. This significantly contributes to the reliability and efficiency of drone systems.
A highlight of Hitec’s portfolio is the SR33BL servo. This model features dual motorization. In the event of a motor failure, the second motor seamlessly takes over its function. This high level of redundancy significantly increases operational reliability, a critical factor for drones and other unmanned applications. In particular, the redundancy of the SR33BL servo addresses a key challenge in safety-critical drone applications, such as delivery operations, inspection flights over populated areas, or potentially in the field of passenger drones. Increased reliability of control components is essential here to minimize risks and further promote the acceptance of unmanned systems.
In addition, there is a growing demand for specialized servos. These include, for example, models with dual outputs or particularly lightweight designs that meet the specific requirements of modern drone designs.
