The robotic arm itself is a 6 Degrees of Freedom (6DOF) model, which means it can move in six different ways: up and down, left and right, forward and backward, and it can also rotate around three ...

Pedro 2.0 is a simple 3D-printable robot arm intended for STEAM education. ... and an Arduino running the show. There’s also an NRF24L01 module for wireless remote control.

The 1-DOF robot was fixed to the F/T sensor and pulled the 2-DOF robot at a constant speed. Credit: IEEE Transactions on Neural Systems and Rehabilitation Engineering (2025).
