Hiwonder HTD-85H Intelligent Serial Bus Servo Stainless Steel Gear 85KG High Torque

The Hiwonder HTD-85H is a high-torque intelligent serial bus servo designed for demanding robotics projects. Featuring robust stainless-steel gears and a powerful motor, it is an ideal choice for South African makers, educators, and hobbyists building heavy-duty robotic joints.

Simplified serial bus wiring

The servo connects to an I/O port and supports daisy-chaining in series through dual interfaces. This serial bus connection minimises wiring complexity and reduces clutter in your robotic builds.

High-performance stall torque

Powered by a self-developed high-performance motor, this servo delivers a massive stall torque of up to 85 kg·cm at 11.1V. This provides your robot with strong, reliable power for heavy-duty movements.

Customisable ID and bus communication

Each servo can be assigned a unique, fully customisable ID, with the default set to 1. The controller communicates with the servos over a single bus at a baud rate of 115200, ensuring stable and efficient data transmission.

Anodised metal middle case

Featuring an anodised metal middle case, this servo ensures excellent heat dissipation and enhanced durability. The robust housing protects internal components during demanding operations.

Real-time position feedback

The intelligent bus servo supports real-time angle feedback, allowing you to read back positions quickly. This feature makes it easy to monitor servo positions and accurately capture robot joint movements.

Voltage and temperature protection

Built-in temperature and voltage feedback systems allow you to monitor internal data in real time. This continuous feedback helps protect the servo from damage during operation.

Durable stainless-steel gears

Equipped with high-strength stainless-steel gears, this servo offers outstanding stability and wear resistance. The rugged gear train is built to withstand high-stress robotics applications.

Dual operating modes

In servo mode, rotation and positioning can be precisely controlled within a 240-degree range. In geared motor mode, the servo supports continuous 360-degree rotation with controllable speed and direction.
