Engineer and creator James Bruton, renowned for his innovative technological projects, has presented his latest breakthrough in a video shared on his YouTube channel: a one-of-a-kind omnidirectional bicycle that uses spherical wheels to allow movement in all directions.
In the nearly 28-minute video, Bruton details the design, manufacturing and testing of this vehicle, combining advanced technology, 3D printing and creative solutions to complex engineering problems.

Spherical wheels: the keys to the omnidirectional bicycle
The bike is based on two rigid spheres, commonly used in circus acts, which are driven by omnidirectional wheels . These wheels, arranged at a 120-degree angle, allow for precise maneuvers and linear or lateral movements. To ensure stability, the vehicle uses Hall effect sensors and O-Drive controllers, capable of dynamically adjusting speed, torque and position.
The structure was made from 3D printed parts, using large-bore nozzles to print robust components and 4040 aluminum extrusions, known for their strength and flexibility in modular assemblies. Additionally, Bruton used custom aluminum plates , manufactured by PCBWay, to secure mechanical connections between parts.
Challenges overcome, tests and final adjustments
Key challenges included preventing the wheels from slipping on the spheres and managing the build-up of static electricity , which affected the electronic components . To address this, an electrical grounding system was designed that connects all the metal components, preventing static discharges. PID parameters were also adjusted to optimize balance, inspired by an earlier Bruton project, his “screw bike.”
In initial testing, the bike proved capable of balancing and maneuvering effectively , even with the weight of the rider. Bruton implemented manual controls on the handlebars, including twist grips to adjust direction and speed. Although the vehicle can move in any direction, Bruton noted that it requires further adjustment to improve traction at high speeds and maneuver in tight spaces.
A breakthrough in omnidirectional vehicles
With this project, James Bruton continues to redefine the boundaries of engineering and technology applied to mobility . His omnidirectional bicycle is an example of how innovation, experimentation and the use of modern tools such as 3D printing and advanced control systems can open up new possibilities in vehicle design.
The video has already caught the attention of technology and engineering enthusiasts, standing out as a benchmark in the development of disruptive solutions.
