Microfluidic devices present a versatile means of working with microscale objects. Here we present a new class of microfluidic design and devices that enable control of small objects without the use of traps. The chosen geometry enables symmetry-protected functionality, separating out 3D directional control from straining flow. An experimental implementation of this device allows for strainless, arbitrary path generation both with and without feedback control. Overall, the device provides a new means of micromanipulation to address experimental needs for precise motion and strain control.
