Mount the wheels onto the motor shafts using the included couplers or direct shaft fittings, then install the caster wheel assembly at the rear or front depending on your weight distribution requirements. Attach your microcontroller board using M3 standoffs at the designated mounting points, and route motor power wires through the integrated cable channels to prevent entanglement. Connect the motor terminals to your motor driver module (L298N or similar) ensuring proper polarity, then mount your sensors such as ultrasonic modules or IR sensors at the front-facing M3 threaded inserts using small brackets.\u003c\/p\u003e\n\n\u003cp\u003eProgram your microcontroller with motor control logic using PWM signals to regulate wheel speed and direction, implementing differential drive equations for smooth turning and rotation. Test motor responsiveness by applying incremental PWM values from 0-255 to verify all four motors respond proportionally. Calibrate sensor readings by taking baseline measurements in your operational environment, then implement your autonomous navigation algorithm whether it be line-following, obstacle avoidance, or waypoint-based navigation. Secure your battery pack to the chassis using velcro strips or zip ties, positioning it centrally to maintain balanced weight distribution. Perform test runs in a controlled environment before deploying your robot for its intended application, monitoring motor current draw and sensor accuracy throughout operation.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat motor specifications are compatible with this chassis?\u003c\/summary\u003e\n\u003cp\u003eThis chassis accommodates standard 3-6V DC geared motors with shaft diameters between 3-6mm and output speeds ranging from 65-200 RPM.
