PUNA is a simple hexapod meeting precision positioning applications in research or industry with an optimized budget.

Indeed PUNA hexapod can meet limited budgets while offering a resolution of 0.5 µm in translation and 5 µrad (0.0003 °) in rotation for a payload capacity of 25 kg.

To simplify the design, the motor is mounted in line and incorporates an incremental rotary encoder.
