Milos takes his servo driven robot arm off the bench and turns it into a four wheel drive mobile platform built around the NXP FRDM RW612. The project combines an aluminium extrusion chassis, DC geared motors with L298N drivers, PCA9685 servo control, and wireless joystick input to tackle real challenges like torque, calibration, surface traction, and jitter. On the software side, he moves beyond joint by joint control into inverse kinematics and Cartesian motion, using simulation to validate behaviour before driving real hardware. The result is a modular robotics platform designed for learning, iteration, and future upgrades, and the supporting files are on the element14 Community: bit.ly/4uBsZMz
