20251ROB2: Industrial Manipulator - Robotic Arm
Brief Introduction & Functionality
An industrial manipulator is a type of robotic arm designed to mimic the movement and functionality of a human arm, often used in manufacturing, assembly, and material handling applications. These robotic systems are composed of multiple joints and actuators, allowing for multi-degree-of-freedom (DOF) movement and precise control.
OpenManipulator, an open-source robotic arm by ROBOTIS, is a popular lightweight manipulator used in research and education. However, its payload capacity (~500g) limits its industrial applicability.
To address this, we propose the development of an updated manipulator, inspired by OpenManipulator’s modular design and ROS compatibility, but engineered to carry heavier payloads up to 4–5 kg, making it suitable for semi-industrial and small-scale automation tasks.
