FAIR plus 2026: A First Look | The 699-yuan ‘harmonic joint’ is here！
On 22 April 2026, the second Robot Industry Chain Expo (FAIR plus 2026) officially opened at the Shenzhen Futian Convention and Exhibition Centre. As the ‘flagship event’ of the robotics industry chain to kick off the year, this year’s exhibition brought together more than 500 companies from across the industry chain.
Cancer Intelligence caught the eye of trade visitors with its ‘unbeatable value for money’ and ‘cutting-edge full-stack technology’. If you’re curious to see what the ‘agile joints’ of humanoid robots are like, please join us as we take a look around the Cancer Intelligence stand.
The new R48-Lite harmonic joint, renowned for its precision and ‘agility’, is attracting considerable attention
The most talked-about ‘star’ product from Cancer Intelligence is undoubtedly the all-new R48-Lite harmonic joint module, launched in early April. Designed specifically for high-frequency motion and high-dynamic-response areas of humanoid robots, such as the neck and wrists, this product is ‘precise and agile’.
The ultimate in ‘lightness’ and ‘compactness’: the module has an outer diameter of 48 mm, a length of just 45.5 mm, and weighs as little as 0.26 kg. Compared with the previous generation, the length has been reduced by approximately 8 mm, which means robot designers have more space to work with when planning layouts.
Outstanding performance: Despite its compact size, it delivers a rated torque of 5 Nm and a peak torque of 11 Nm. Combined with a reduction ratio of 101:1, this enables flexible neck movement and precise wrist gripping.
A pricing revolution: Cancer Intelligence unveiled a pricing strategy of 699 yuan per joint at the event. This pricing directly addresses a key industry challenge, significantly lowering the barrier to entry for the development of high-precision robots.
In addition to the much-talked-about R48-Lite, Cancer Intelligence—a company with in-house R&D capabilities spanning the entire technology stack, including harmonic reducers, frameless torque motors, dual-magnetic encoders and drive control—showcased a comprehensive portfolio of solutions covering robotic joints.
1. Harmonic reducer: As the ‘heart’ of the articulated module, Cancer Intelligence has introduced its own high-precision harmonic reducer. With sub-micron manufacturing precision and rigorous heat treatment processes, it has broken the long-standing foreign technological monopoly; this is also the key factor underpinning our ability to ‘drive down’ costs.
2. Full range of joint module matrices: To meet the load requirements of different parts of humanoid robots, Cancer Intelligence showcased a range of modules including the R58, R68, R83 and R120 series. These modules cover a variety of applications, including the head, shoulders, wrists, waist and hips. The entire range comes standard with 21-bit dual encoders, enabling high-precision closed-loop control of position and velocity. Comprehensive coverage of application scenarios: whether it is high torque output at the waist or the need for agile movement at the neck, Cancer Intelligence can provide standardised solutions.
3. Humanoid robotic arm: At the event, Juxie Intelligence conducted a dynamic demonstration of its robotic arm. This product deeply integrates the principles of ergonomics and biomechanics; not only does it feature a highly biomimetic 7-degree-of-freedom design, but it also boasts an exceptional modular architecture that supports secondary development and in-depth customisation by users, making it an ideal experimental platform for the practical implementation of ‘embodied intelligence’.
