Ti5 Robotics 30-40 Lightweight Joint Module
Ti5 Robotics 30-40 Lightweight Joint Module is a compact rotary actuator family that combines a motor, precision gear reducer, encoder and drive electronics in a single integrated housing. Developed by Ti5 Robotics for robot joints where mass and volume are at a premium, the 30-40 series is offered in four joint versions and two gear ratios, allowing designers to balance torque, speed, body length and communication interface for each axis of a machine rather than accepting a one-size-fits-all actuator.
Background
Why integrated joint modules matter
Traditional robot joints are assembled from separately sourced motors, gearboxes, encoders and servo drives, which increases wiring complexity, weight and engineering effort. Integrated joint modules collapse that chain into one unit, typically with a through-going hollow shaft for cable routing. Ti5 Robotics positions the 30-40 series around three qualities: modularity that supports flexible assembly and easy maintenance, a lightweight structure that enhances mobility and energy efficiency, and a highly integrated layout that optimizes space utilization and performance output for modern intelligent equipment. The manufacturer supplies such actuator modules ready for integration into humanoid robots and other machines.
The 30-40 model family
The series comprises four joint versions built on the same 30-40 frame: the base CRA-RI30-40-PRO-2-XXX, the extended-body CRA-RI30-40-PRO-2-XXX-B, the CRA-RI30-40-PRO-2-XXX-2E-EC with a dual-encoder configuration and an EtherCAT-capable interface, and the CRA-RI30-40-PRO-2-XXX-B-2E-EC, which pairs the extended body with that interface option. Each documented version is offered with a 51:1 or a 101:1 gear ratio, trading output speed against torque. The manufacturer lists the fourth version by name but does not publish a parameter table for it, so only the three documented versions are quantified below.
Technical Specifications
The following tables preserve the published configuration distinctions. Blank, malformed, or ambiguous source values are not confirmation of a capability; confirm the selected configuration during quotation.

How do the four versions of the 30-40 joint module differ?
Torque, speed, backlash and electrical ratings are identical across the documented versions for a given gear ratio; the versions differ in packaging and interface. The B version uses a longer body — 78.6 mm versus 60.5 mm — and is correspondingly heavier at 0.27 kg versus 0.19 kg for the base unit. The 2E-EC version keeps the short 60.5 mm body but adds a second encoder option at 16/18-bit resolution and supports EtherCAT alongside CAN, at a mass of 0.23 kg. The B-2E-EC version nominally combines the extended body with the dual-encoder EtherCAT configuration, but its parameters are not published, so it should be specified only after direct confirmation with the factory.
Who is the Ti5 Robotics 30-40 Lightweight Joint Module for?
The 30-40 series targets OEM robot builders, research laboratories, system integrators and product development teams that need a small, low-mass rotary joint with documented torque and speed figures. It suits engineers designing distal axes — wrists, grippers and small limb joints — where every gram matters, as well as educators and researchers who want a self-contained actuator with a hollow shaft for clean cable routing and a standard CAN or EtherCAT control interface. Buyers choosing among the four versions should start from required torque, available axial length and the fieldbus used by their controller.
What is the Ti5 Robotics 30-40 Lightweight Joint Module used for?
- Joint axes in humanoid robot limbs, where the manufacturer supplies actuator modules ready for integration.
- Wrist and distal joints of collaborative robot arms that need low moving mass.
