Engineering for Embedded & Robotics

Sense. Connect. Actuate. Validate.

Akrodyn develops complex systems for Embedded & Robotics: PCB design, firmware, custom motion control, power electronics, safety and edge AI. From test bench to series production.

Akrodyn develops your custom motor controller for servo/BLDC motors with our own high-dynamic, precise control algorithms. From robotics actuators for autonomous vehicles to complex synchronised multi-axis systems, e.g. for X-ray equipment — together we solve your specific challenge. We operate in the custom-made space, but have built a supply chain for you to deliver tens of thousands of controllers at competitive prices.

Akrodyn guides machine and device manufacturers through the entire safety process. From normative analysis and system architecture design through to passed certification with an external testing body. We specialise in the development of test benches. We build and commission them in-house and ship them worldwide.

Normative Foundations

Risk assessment to ISO 12100, performance evaluation to ISO 13849. FMEA, FTA and SISTEMA calculation for safety-relevant control functions.

Safety Architecture

System design up to PLe and SIL 3. Single-channel and dual-channel redundant structures with safe communication and diagnostic functions.

TÜV Support

Guidance through the entire certification process. We establish contact with the selected testing body from the very start, so that their requirements are factored into the design.

EMC Testing

Preparation and support for EMC testing to EN 61800-3 C2/C3 for drive systems in industry and infrastructure.

Your customers want reliable AI devices without a permanent internet connection and backend? Together we build the hardware and adapt AI models for deployment on microcontrollers or embedded Linux systems. We equip the hardware with autonomous functions such as GNSS (GPS) and connect the field devices via LoRaWAN or satellite internet.

TinyML on Microcontrollers

Model compression, quantisation (INT8) and inference on STM32, NRF52 and ESP32. Classification, anomaly detection and prediction without cloud.

Computer Vision

Object detection (YOLO, MobileNet), OCR and semantic segmentation on edge processors. Camera integration, ISP tuning and image preprocessing.

Autonomous Systems

Lidar-based environment perception, multi-sensor fusion (IMU, GNSS, camera) and reactive path planning for mobile platforms and industrial robots.

Connectivity & Field Devices

5G NTN (satellite internet), LoRaWAN and GNSS for self-sufficient IoT devices in remote areas without terrestrial network coverage.

Why Akrodyn

Why customers choose Akrodyn

  • We don't only build for others.

    Brake choppers and motor controllers: we have our own products in series production. What we develop for you is the same road we have already walked for ourselves.

  • EMC testing before it gets expensive.

    Our measurement bench is in-house. We find the interference during development, not in an accredited lab three weeks before series release.

  • You talk to the engineers.

    No ticket system. We are a small company, so you simply reach the people who are working on your project with you.

  • Deep technical competence.

    Risk analysis to ISO 12100 and 13849, safety concepts up to PLe and SIL 3, TÜV support and the V-model: not as a slide, but as a way of working and a result.

Engineering sparring

Got an idea or a project? Let's get started.

One hour, free of charge, by video or at our place in Zurich. We look at where the technical risks are, what can be shortened and what the next sensible step would be. No pitch, no slide deck. You leave with more clarity than you arrived with — even if we never work together.
