A robotic arm was created by YouTube maker Thomas Sanladerer, which was primarily intended to hold a digital camera that can take photographs from a variety of angles.
Thomas built the arm using a linear rail that pushes or pulls the next section of the arm, mimicking the actions of human muscles.
The arm is made from a combination of 3D printed sections and aluminium hollow stock, with the head featuring three Waveshare ST3215 servos with internal magnetic encoders.
The total cost of the arm is a few hundred Euros, which, for a nine-degree robotic arm, is considered reasonable.
However, Thomas has encountered issues with the steppers skipping steps and one of the servos burnt out during testing, meaning he is considering replacing them with brushless motors.
