Hiwonder Serial High Voltage Bus Servo HTS-21H Anti-burning and Anti-blocking Intelligent Serial Port High Torque High Precision with Feedback Dedicated for Robot Gripper Claw

The Hiwonder HTS-21H is an intelligent high-voltage serial bus servo designed specifically for robotic gripper claws and joint mechanisms. Featuring built-in anti-blocking algorithms and real-time feedback, it is an excellent choice for South African students, educators, and hobbyists building robust robotic systems.

Smart anti-blocking protection

An internal controller chip runs a built-in anti-blocking algorithm to prevent the servo from burning out during stalls or collisions. This protective feature significantly extends the operating lifespan of your robotic joints.

Dual operating modes

This versatile servo supports both standard servo mode and geared motor mode. In servo mode, you can control precise positioning within a 240-degree range, while the reduction motor mode allows continuous 360-degree rotation with speed and direction control.

Energy-efficient high-voltage operation

Operating at 11.1V, this high-voltage servo reduces current draw by more than 60% compared to traditional 7.4V alternatives. This efficiency dramatically improves the overall battery life of your mobile robots.

Real-time telemetry and feedback

Keep track of your robot's status with integrated temperature, voltage, and angle feedback. The angle readback feature allows controllers to quickly capture precise joint positions for advanced motion planning.

Durable stainless steel gears

The internal gear train is constructed from high-quality stainless steel to enhance wear resistance. This robust metal construction ensures long-term reliability under high-torque demands.

High-temperature resistant motor

Equipped with a specialised high-temperature resistant motor, the servo is protected against premature aging and burnout. This ensures safe and stable operation even during demanding, prolonged use.

Daisy-chainable bus communication

The servo communicates over a single bus at a baud rate of 115200, allowing you to daisy-chain multiple units. Each servo has a customisable ID, which defaults to 1, simplifying wire management in complex builds.

Standardised physical design

The HTS-21H shares the exact same physical dimensions and external structure as the HTS-16L model. The primary distinction lies in their operating voltages, allowing for easy drop-in upgrades.
