EEZYbotArm MK3 with micro servo

thingiverse

Instead of converting a unipolar 5-wire 28BYJ-48 stepper motor to bipolar 4 wires to boost torque output, I chose to integrate two MG90s micro-servos that provide robust support. Additionally, I created custom gear wheels with specialized spacers. To adapt the MK2 gripper to the MK3 model, I made a seamless transition, ensuring a smooth upgrade path for users. I designed a sturdy support system for the KY-008 laser module, which can be easily attached to the STL file EBA3_004. Furthermore, I developed a feedback mechanism using photoresistors and photocells that send rotation data directly to the Arduino board. To take control of the robotic arm wirelessly, I developed an Android application that enables users to manipulate the device with ease.
