As Synchrodrive refers to a form of propulsion for robots . In this process, the wheels all turn at the same speed and direction. Straight-ahead travel is mechanically guaranteed.

One motor drives all the wheels, a second motor changes the direction of travel by turning all the wheels around a vertical axis at the same time. Since the changes are made by one motor each, the control is simpler than, for example, with a differential drive . Furthermore, the platform does not rotate with it. Equations for calculating the movement trajectory of a Synchrodrive vehicle can be found, for example, in the lecture materials of the University of Freiburg. Simple implementations of the Lego principle (including building instructions) can often be found on the Internet, for example by Mark Crosbie.

A frequently used robot platform with Synchrodrive is the B-21 from RWI (today iRobot).
