Overview
The Chopsticks Actuator is a compact linear actuator designed for high force output and precision control. It utilizes a brushless DC (BLDC) motor coupled with a planetary gearbox to achieve efficient power transmission and smooth operation. The actuator is capable of delivering significant force while maintaining a small form factor, making it ideal for applications in robotics, automation, and assistive devices.
Design and Development
The design process involved extensive research into motor control, mechanical design principles, and materials selection. The actuator features a planetary gearbox that provides a high gear reduction ratio, allowing the BLDC motor to operate at its optimal speed while delivering increased torque. The linear motion is achieved through a lead screw mechanism, which converts the rotational motion of the motor into linear displacement.
Prototyping and Testing
Multiple prototypes were developed using 3D printing and CNC machining techniques. Each iteration focused on improving the efficiency of power transmission, reducing backlash, and enhancing the overall durability of the actuator. Testing involved measuring the force output, speed, and precision of the actuator under various load conditions to ensure it met the desired performance criteria
