4DoF acrylic robotic hand without servos

Product detailed description

Lightweight and modular robotic arm with 4 degrees of freedom (4DoF), made of black acrylic, is a great base for learning robotics, programming and construction of controlled mechanisms. In this variant, it comes without servo motors, which allows you to use your own motors as required (e.g. SG90 etc.).

Key features:

• 4 degrees of freedom - movement at the shoulder, elbow, wrist and grip
• Lightweight and strong acrylic construction
