Motion Control & Robotics
Motion is our core discipline. We design the drives, write the control laws, synchronize the axes and tune the machine, from a single 16 mm BLDC controller to a 26-axis theatre rig moving above an audience.
Motor drives & control
Field-Oriented Control (FOC)
Custom FOC drives for BLDC/PMSM: analytic current loops, SVPWM, four-quadrant operation.
Every motor family
BLDC, DC, stepper (open and closed loop), AC servo and special/custom machines.
Custom drive electronics
From 5 V micro-drives to 100 V / 30 A industrial stages, with isolation where it matters.
Critical control loops
Current, velocity and position loops, designed, tuned and verified against spec.
Advanced control
Feedforward, gain scheduling, disturbance observers, anti-resonance filters for flexible loads.
Multi-axis systems
EtherCAT machines
Deterministic multi-axis synchronization with distributed clocks: dozens of axes in lockstep.
Fieldbus integration
CANopen (DS402), PROFINET, Modbus: drives, I/O and safety on one network.
Trajectory generation
Profiles, blending, camming, electronic gearing: motion that is smooth by design.
Kinematics & dynamics
Forward/inverse kinematics, dynamic models and simulation before metal moves.
Robotics
Vision-guided robotics
Cameras closing the loop: pick-and-place, alignment, tracking, inspection-driven motion.
Custom robotic mechanisms
Non-catalog axes: special grippers, balancing platforms, surgical-grade motions.
ROS / ROS 2
Prototyping and productizing robot stacks where the ecosystem fits the problem.
Force & impedance control
Contact-rich tasks (assembly, polishing, medical tools) controlled in force, not just position.
Feedback, safety & commissioning
Feedback systems
Absolute/incremental encoders, resolvers, Hall arrays, IMUs: selection, wiring, signal hygiene.
Machine safety
Hard-wired e-stops, STO, limits and supervised states designed for loads above people.
Actuator & gearbox sizing
Torque/inertia math done honestly: motors that fit the move, not the catalog page.
On-site commissioning & tuning
We bring the machine to spec where it lives, measurement-driven and documented.
Motion specification
Loads, profiles, accuracies, safety class: the numbers that drive everything.
Architecture & sizing
Drive topology, feedback, bus, motors, simulated and sized before purchase.
Control development
Loops implemented and tuned against the spec, with margins demonstrated.
Integration & commissioning
On the real machine: synchronization, safety validation, operator handover.
Can you work with motors and drives we already bought?
Yes. We tune and integrate third-party drives daily (Technosoft, Beckhoff, Mitsubishi, Yaskawa and others), and design custom drives when the catalog runs out.
What accuracy can you reach?
It depends on mechanics and feedback, not wishes. We've delivered ±1 cm on 26 synchronized winch axes and ±0.002° on precision tilt sensing, and we'll tell you honestly what your mechanics can support.
Do you handle safety for motion above people?
Yes: hard-wired e-stop chains, software/hardware limits, mode-dependent speed restrictions and load monitoring. Our theatre rigging work moves tons above audiences.
Can you just tune our existing machine?
Absolutely. Commissioning and tuning of existing axes (including 'it oscillates and nobody knows why') is a service on its own.
