Pushing the Boundaries of Robotics: Advances in 3D Printed Wheels and Drone Motors


Padmalaya Rawal, an innovator in robotics, has created a fast robot wheel utilizing 3D printing technology and a modified drone motor. This novel design tackles the shortcomings of traditional slow, yellow-colored BO motors and their respective wheels. Rawal’s design offers a compact, cost-effective, and quicker substitute, amplifying his robotic innovations’ operation.

The technique Rawal implements involves modifying a brushless DC motor, commonly utilized in drones, to energize the robot wheels. This alteration involves bisecting the motor and modifying the shaft’s height – a procedure that requires vast pressure, occasionally needing the use of a hammer. The retouched motor is then combined with a 3D printed wheel hub, which includes support pins for stability. A rubber tire from a standard battery-operated motor kit is added to enhance traction.

The wheel composition includes the lower half of the motor lodged in the 3D printed wheel, while the upper half links to a 3D printed mount. Rawal tested the wheel with an Electronic Speed Control (ESC) tester, operating it at 50% capacity for safety measures, given the wheel generates considerable power.

For those with an interest in studying or improving this design, Rawal provides the STL files for the wheel hub and motor mount on his Instructables page. This strategy for creating robot wheels might incite further investigation into economical and high-performance robotics designs.
