Grab-It robotic arm + Joy-iT ARD-MOTO3 controller

Discover the Grab-It robotic arm made of aluminum, delivered with the Joy-iT ARD-MOTO3 power controller, a complete and powerful solution for educational and experimental robotics projects.

Features
The Grab-It robotic arm is designed to combine robustness and precision. Equipped with 6 high-performance servomotors with high torque (21.5 kg.cm), it allows a wide range of movements: rotation, tilt, gripper opening/closing, as well as shoulder, elbow, and 360° base rotation. The arm is supplied as a DIY kit, including servomotors, gripper, mounting hardware, and rotating base. An assembly manual (English) and programming examples are available for download. The kit also includes the Joy-iT ARD-MOTO3 power controller, specially designed for Arduino Uno and Mega. Based on the PCA9685 chip, it offers precise positioning thanks to its internal clock generator and allows you to control up to 16 PWM servomotors. The board includes a built-in filter capacitor (with the option to add a second one via a dedicated terminal block) to ensure stable and reliable power supply. This complete pack is ideal for learning robotics, prototyping, and advanced projects requiring power, precision, and scalability.
