Challenges and Solutions
We understand and have targeted solutions.
Difficult to fix, easy to fall off
Traditional adhesives or general-purpose foot pads are extremely prone to displacement and loosening under high-frequency vibration and impact loads, leading to unstable posture of the robot, walking deviation or even falls. Once the foot pads fall off, it will not only cause the whole machine to shut down, but may also damage expensive joint modules and sensors, resulting in high maintenance costs.
RobotSole adopts a composite wrapped structure and an integrated design of the foot sole plate (several patents have been applied for). It realizes glue-free fixation without relying on standardized interfaces, is firm and tight, and can withstand intense sports and long-time walking. The modular design greatly reduces maintenance costs, making sole replacement as simple and fast as changing a tire.
Lack of buffer, high noise
Ordinary rubber mats lack effective cushioning protection. The peak impact force when the robot's feet land can reach 2-3 times its own weight. This not only causes high walking noise, but also causes fatigue damage to core components such as joint modules and reducers, shortening the service life of robot components.
RobotSole has developed a double-layer gradient buffer structure + high-performance TPV damping material. Through the soft-hard layered energy absorption design, the impact force is dispersed step by step, which greatly reduces the walking noise of robots, meets the silent scene requirements of home and industrial environments, and effectively protects the joint modules and extends the overall service life.
Flat foot structure, poor passability
Most humanoid robots have flat-foot structures, making it difficult to adapt to terrains such as steps, slopes, gravel, obstacles and other terrain, with weak obstacle-surmounting ability and prone to tripping or getting stuck on complex road conditions. This severely limits the application of robots in real scenarios such as outdoors, workshops and indoor spaces, leaving them only able to stay in flat laboratory environments.
RobotSole adopts a front-rear warped design and bionic shape suitable for robot soles, which not only significantly improves the passability on complex roads, makes the robot's feet more aesthetically pleasing, but also more in line with the general human aesthetics.
The anti-slip and wear-resistant performance is insufficient.
Ordinary rubber shoe soles are extremely prone to slipping in scenarios such as wet, oily, and sloped conditions, posing serious safety hazards. Meanwhile, the mainstream wear-resistant service life is only 2000-3000 hours, which is far lower than the 10000-hour-plus usage requirements in industrial scenarios, and frequent replacement affects production efficiency.
RobotSole adopts sole structures and texture designs tailored for different scenarios. Combined with features including slip resistance, wear resistance, high and low temperature aging resistance, anti-static, oil and water resistance, and targeted hardness gradient adjustment, it maintains excellent grip even in various complex scenarios, extends its wear life to over 8000 hours, and is particularly suitable for various harsh industrial and field standards.
Wide range of models, fast renewal, lack of standardized accessories for the foot sole
There are numerous types of robots, with fast updates and upgrades and diverse application scenarios, which leads to a large number of supporting molds with different interfaces, high costs, difficult maintenance, poor interchangeability, and it is also difficult to quickly replace standardized foot soles according to the needs of different users.
RobotSole launches the integrated standard foot module system made of carbon fiber and TPV. It will support unified mechanical and electrical interfaces in the future, and allows on-demand selection and rapid expansion. It has shifted from the "customized for each product with repeated mold opening" model to the "standard selection, plug-and-play" model, greatly reducing supply chain complexity and promoting the industry's standardization process.
The contradiction between lightweight and high strength
Currently, the commonly used metal foot sole structures cannot be integrated with rubber and foamed cushioning sole materials, requiring screw fixation and being relatively heavy. The ultra-thin design is prone to fatigue fracture, making it difficult to balance lightweight and high strength, which has become a key bottleneck restricting the performance improvement of robot foot soles.
RobotSole adopts integrated carbon fiber molding + topology optimization design. The structure is reinforced in key load-bearing areas and extremely thinned in non-load-bearing areas, achieving "strength where it needs to be strong, lightness where it needs to be light". It reduces weight by 40-60% without sacrificing strength, completely solving the industry dilemma of "soft when light, heavy when rigid".
