Actuators
Our development tools include mechanical design (CAD), structural design (FEM), control design (Matlab) and electronic design (Altium).
Our workshop is also organized to manufacture prototypes and small series in-house, allowing reduced development time and efficient delivery of dedicated solutions.

What we do
- Review of specifications
- Conceptual Design
- Review & trade-off of potential actuator technologies (Piezo, pneumatic, electro-magnetic, hydraulic etc.)
- Review & trade-off potential sensor technologies
- Review of control algorithm
- Prototyping & evaluation
- Detailed Design
- Structural Analysis
- Control Analysis
- Electronic design
- Mechanical manufacturing drawings
- Procurement and assembly
- Calibration & Final acceptance tests

Telescope Mirror Shaping Actuators
For telescope manufacturers, we design and manufacture high-precision pneumatic actuators which are used to shape large telescope mirrors. For these applications, the primary mirror of the telescope is equipped with a set of axial force actuators in order to compensate for the low frequency surface shape errors (i.e. gravity effects, thermal effects, manufacturing etc.). The control strategy is usually a decentralized approach, where each actuator is equipped with its own local control electronics and communication electronics. Therefore, the telescope operator can change the mirror shape by sending a map of correction forces to the network of actuators.
Thanks to the embedded control electronics, the actuator can perform the following actions:
- Acquire the sensor signals
- Derive the actuator
- Perform the non-linear closed-loop control
- Perform the actuator calibration
- Perform actuator diagnosis
- Run the local state machine and communication with the host
These actuators equip telescopes in India (ARIES, MT ABU), Hawai (Pann-Starrs, Daniel K. Inouye Solar Telescope-DKIST) and Turkey (DAG).
