SCIENCE AND ENGINEERING BEHIND OMNIDIRECTIONAL VEHICLES
Step into the world of tomorrow with BEA Technologies. We bring you the latest advancements in omnidirectional vehicle technology from our groundbreaking research and development.
Hardware development
Universal Modular Fabrication
We have meticulously designed a universal module to serve as the cornerstone of our omnidirectional vehicles. Due to its versatile and efficiency solutions for various applications, this module is adapted to seamlessly integrated across our product line, including omni-chairs, omni-karts, omni-cars, and upcoming products. Notably, we have filed two patents for our module design: one focusing on the mechanical components and the other on the electrical components.
Mechanical Components
In the realm of mechanical innovation, we have implemented our Intelligent Rotation System (IRS), enabling the wheels to rotate freely without wire entanglement or drive shaft restrictions.
Furthermore, emphasizing durability, our module is meticulously crafted from sturdy materials, with 90% of its components made of steel. Engineered for heavy-duty applications, a single module can effortlessly support weights of up to 400lbs (182kg).
Electrical Components
To ensure optimal power transfer to the wheels, we have implemented a high-power slip ring custom-designed by our team. This specialized component delivers ample and seamless power to the wheels while also withstanding electrical wear and tear effectively.
Position Sensors
Precision is critical when come to reliability in steering design. That's whey we utilize a high-resolution 14-bit 360-degree sensor to detect wheel position with an impressive sensitivity of as little as 0.02 degrees. In addition to precise angle detection, we employ a rapid refresh rate of 1 millisecond to further enhance performance.
High Torque Steering Motor
Our omnidirectional vehicle requires continuous movement to create a hovercraft-like dynamic effect. To achieve this , we have developed a mechanical mechanism utilizing a high-torque motor with 45 lb-ft (67.78 Nm) of torque. This design ensures robust and precise control, leading to improved performance and maneuverability.
Compact Size
Our module is designed with a compact form factor in mind, measuring just 11 inches x 9 inches x 5 inches (W x L x H) (28 cm x 25 cm x 12.7 cm). To put into perspective, it's about the size of a pink donut box. Despite its small size, each module is powerful enough to move over 400 lbs of load. For our Omni-chair application, we used two modules and both together can easily fit within the 26-inch diameter area of an office chair base, showcasing its compact yet robust design.
