Development Process
The project was executed over three months, beginning with extensive breadboard and electronics prototyping. Initial chassis designs were iteratively refined through 3D printing, while the electronic systems were developed on breadboards before finalizing the custom PCB design. The control software underwent multiple revisions to achieve precise movement and reliable wireless communication. Final assembly included comprehensive testing and calibration of all systems.
