We report the design and development of a piezoelectric sample rotation system, its integration into an Oxford Instruments Kelvinox 100 dilution refrigerator, for orientation-dependent studies quantum transport in semiconductor nanodevices at millikelvin temperatures magnetic fields up to 10 T. Our apparatus allows continuous situ device through >100° two possible configurations. The first enables field within plane device, second be rotated from in-plane perpendicular plane. An integrated angle sensor coupled with closed-loop feedback system orientation known ±0.03° while maintaining temperature below mK.
