What makes it work
Model: RH56DFTP
FTP Series Dexterous Hand
Dedicated for the Unitree H2 humanoid robot — 6 degrees of freedom, 12 motor joints, over one million cycle lifespan, 3 kg fingertip output force, 12 tactile sensor modules, and hollow-cup brushless motor with planetary roller screw. Human-like strength and precision in one platform.
Groundbreaking Advancements in Lifespan, Load & Tactility
The FTP Series Dexterous Hand integrates multiple groundbreaking technologies, achieving significant advancements across three critical dimensions that define industrial-grade robotic hand performance.
H2 Dedicated — Industrial-Grade Dexterous Hand
The INSPIRE-ROBOTS FTP Series Dexterous Hand (RH56DFTP) is designed exclusively for the Unitree H2 humanoid robot. A single hand features 6 degrees of freedom and 12 motor joints, paired with a hybrid position and force control algorithm that simulates human hand motion for accurate grasping operations. The hand delivers a fingertip gripping force of 3 kg and an overall load capacity equivalent to 15 kg — performance comparable to a human hand. Six built-in force sensors provide real-time feedback on individual finger force distribution, while 12 surface-mounted tactile sensor modules deliver tactile information from all palm areas. The RH56DFTP achieves a repeatability of ±0.20 mm and is available in left-hand and right-hand configurations, with optional wrist attachments for expanded integration flexibility.
Technology Inside the FTP Series
12 Tactile Modules + 6 Built-in Force Sensors — Full-Surface Perception
The FTP Series deploys a dual-layer sensing architecture. Six force sensors are built into the internal structure — one per degree of freedom — providing real-time force distribution feedback from every individual finger during grasping. On top of this, 12 external tactile sensor modules are mounted across the fingertips, finger pads, and palm surfaces, capturing contact information from every area of the hand. Together these two sensing layers enable grip optimisation, slip detection, contact force mapping, and tactile data collection for embodied AI training — all simultaneously, in real time, across every contact point.

Hollow-Cup Brushless Motor + Planetary Roller Screw — 1M+ Cycle Lifespan
The FTP series replaces the conventional DC motor with a hollow-cup brushless motor, eliminating brush wear and dramatically extending motor service life. The traditional lead screw is replaced with a planetary roller screw — a mechanism with significantly higher load capacity and fatigue life, operating with reduced friction and noise under repeated high-speed cycling. This combination of motor and drive upgrades delivers a core component lifespan in excess of one million cycles — more than ten times the lifespan of comparable products using conventional motor and lead-screw technology. The result is a hand designed for sustained industrial deployment, not just laboratory demonstration.
1,000,000+ cycle certified lifespan
6 DOF · 12 Joints · 3kg Fingertip Force · 15kg Overall Load
The RH56DFTP is structured as a five-finger anthropomorphic hand with 6 active degrees of freedom and 12 motor joints — including thumb lateral rotation, thumb flexion, and four-finger flexion. This joint layout mirrors the kinematic structure of a human hand, enabling the full range of grip types required for complex manipulation: power grasp, pinch grasp, lateral pinch, tripod, and enveloping grip. Fingertip output force reaches 3 kg per finger — comparable to human hand strength — with an overall payload capacity equivalent to 15 kg. Position repeatability of ±0.20 mm ensures consistent, reliable grasps cycle after cycle for precision assembly and handling tasks.
±0.20mm repeatability
RS485 / CAN / Modbus TCP — Hybrid Position & Force Control
The FTP Series supports three communication interfaces — RS485, CAN, and Modbus TCP — giving developers full flexibility to integrate the hand into a wide range of control architectures from embedded systems to ROS-based pipelines. The operating voltage is 24V ±10%, quiescent current is 0.25A, and peak current is 4A. The control algorithm implements hybrid position and force control, allowing the hand to simultaneously target joint positions while enforcing force limits — enabling compliant, adaptive grasping that responds in real time to contact feedback. This control architecture, combined with the FTP series' force and tactile sensor stack, supports both tightly scripted manipulation sequences and adaptive reactive grasping policies for embodied AI applications.

Common Questions — FTP Series Dexterous Hand
What is the FTP Series and what makes it different from other dexterous hands?
The FTP Series is INSPIRE-ROBOTS' premium dexterous hand line, launched at the World Robot Conference in October 2024. It integrates three major advancements over previous generations: a hollow-cup brushless motor and planetary roller screw combination that extends lifespan to over one million cycles (10× competitors); 12 surface-mounted tactile sensor modules added on top of 6 built-in force sensors for dual-layer full-surface perception; and a fingertip output force of 3 kg — comparable to a human hand — with an overall load capacity of 15 kg.
Is the RH56DFTP exclusively for the Unitree H2 robot?
The RH56DFTP is dedicated and optimised for the Unitree H2 humanoid robot, ensuring mechanical and electrical compatibility out of the box. The FTP series' RS485, CAN, and Modbus TCP communication interfaces also allow integration with other robotic platforms and control systems, but the mechanical mounting and wrist interface are specifically designed around the H2 form factor. Available in left, right, and pair configurations — with an optional wrist accessory for extended integration flexibility.
How does the dual-layer sensing (force + tactile) work in practice?
The FTP series uses two independent sensing layers simultaneously. The 6 built-in force sensors — one per degree of freedom — measure the force being applied by each finger's actuator in real time, providing internal force distribution feedback. The 12 surface-mounted tactile modules on the fingertips, finger pads, and palm measure external contact forces and surface interactions. These two streams together enable the hand to detect grip onset, monitor slip, map contact force distribution across the hand, and generate rich tactile datasets for embodied AI training — all within the same grasping event.
What communication interfaces does the FTP Series support and how do I connect it?
The FTP Series Dexterous Hand supports three communication interfaces: RS485, CAN, and Modbus TCP. RS485 allows multiple hands to be connected in parallel on the same bus (up to 254 units). CAN supports up to 16,383 devices in parallel. Modbus TCP enables network-based control for distributed systems. The full communication protocol and register description are documented in the INSPIRE-ROBOTS user manual, which is publicly available for download from the official INSPIRE-ROBOTS website. This openness supports secondary development in ROS-based systems and custom control stacks.
What does "over one million cycles" mean in real terms and how is it measured?
One cycle refers to one complete open-and-close motion of the hand. At one cycle per second, one million cycles equates to approximately 11.6 continuous days of operation. In a typical industrial scenario with 8-hour production shifts and multiple daily cycles per task, a one million cycle lifespan translates to years of sustained deployment. This is achieved by the hollow-cup brushless motor (no brush wear) combined with the planetary roller screw (very high fatigue resistance), which INSPIRE-ROBOTS states is more than ten times the lifespan of comparable dexterous hands using conventional motor and lead-screw combinations.
