AUTOMATION
Brushless motor FOC at 5 kHz current loop bandwidth; custom ESC with DSHOT 600 and DroneCAN; IMU + GPS + barometer EKF sensor fusion; LiDAR SLAM navigation electronics; micro-ROS hardware abstraction; TS 15066 PLd cobot safety electronics; and YOLO edge AI — real-time control built for the physics, not the application note.
The Engineering Problem
Robotics Electronics Are Where Firmware Bugs Have Physical Consequences, Not Crash Reports
A motor controller short on bandwidth produces visible mechanical oscillation. An EKF that doesn't handle IMU bias drift accumulates navigation errors that fail at scale. A flight controller that deprioritizes the motor control interrupt produces attitude transients — and at worst, a crash. A cobot safety system that doesn't achieve PLd integrity is a liability. These systems require mechanical dynamics, electronics, firmware, and safety to be co-designed as one.
Custom cobot joint electronics with torque sensing and TS 15066 compliance for specialized geometries that off-the-shelf modules don't support. Custom UAV electronics for inspection, delivery, and defense beyond commercial autopilot platforms. Custom AMR and AGV electronics for specific facility layouts and throughput targets that generic hardware can't achieve.
We design from dynamic performance requirements and safety integrity level outward — joint bandwidth, stability margin, navigation accuracy, and SIL determined first, then actuator and sensor selection, real-time control electronics, sensor fusion firmware, navigation interfaces, and safety function hardware.

Platforms, Protocols & Standards
Tested silicon and proven stacks — no experimental platform dependencies.
UAV, Drone & Autonomous Flight Electronics
Custom Flight Controller. Sinusoidal FOC ESC. BVLOS Datalink. ADS-B.
Custom UAV electronics means genuine flight control engineering for payload, communication, or detection capability beyond commercial autopilot platforms. Propeller blade pass harmonics (50–500 Hz) saturate IMU outputs if not attenuated — passive vibration isolation mount design, digital LPF trade-off between vibration rejection and control loop phase margin, and IMU sampling rate are co-design decisions that determine data quality in flight.
Ground Robots, AMR Navigation & Cobot Safety Electronics
PLd Category 3. TS 15066 PFL. LiDAR SLAM. EtherCAT FSoE.
AMR reliability in a dynamic warehouse is determined by sensor fusion architecture, SLAM implementation, and collision avoidance firmware specific to the sensor package and operating environment. TS 15066 PFL compliance is determined by torque sensor signal conditioning accuracy, safety controller response time, and PLd hardware fault tolerance — not by the presence of a force-torque sensor in the specification sheet.
Agricultural Robots, Inspection Systems & Autonomous Vehicle Electronics
RTK GNSS. Visual Servoing. Drive-By-Wire. ISO 13849 Category 3.
Agricultural robots, inspection systems, and autonomous delivery vehicles share a common engineering foundation — GNSS/inertial navigation, camera and LiDAR perception, real-time autonomous control — applied to fundamentally different mechanical platforms, environmental qualifications, and safety requirements. Field robots face dust, water, crop canopy GPS multipath, and temperature extremes; delivery vehicles operate in public spaces where navigation failures have immediate pedestrian safety consequences.
Why Robotics Engineering Teams Choose Ankh
Real-Time Motor Control from the Physics
FOC at required current loop bandwidth — with dead-time compensation tuned for the specific motor's flux linkage and current measurement timing centered to the PWM cycle — is fundamentally different from an application note implementation that works on an eval board but produces torque ripple at production motor and load conditions. We design for the specific motor and mechanical load, validated on production hardware.
Sensor Fusion for the Deployment Environment
An EKF sub-metre accurate in open-field GPS accumulates unusable errors in GPS-multipath warehouses. A VIO system robust in good lighting loses tracking in low-contrast environments. A magnetometer working outdoors is corrupted in factories with high-current drives. We design sensor fusion for the specific deployment environment — sensor selection, filter design, and fallback behavior engineered for the failure modes that environment produces.
Safety Functions That Achieve the Required Integrity Level
A cobot with a force-torque sensor is not TS 15066 PFL compliant unless the safety function processing that sensor, comparing it to limits, and stopping the drive within response time has PLd/SIL 2 integrity with appropriate hardware fault tolerance. We design safety electronics with the required integrity level as a design input — not a certification applied to a finished product.
ROS2 Hardware Interfaces That Deliver Real-Time Performance
micro-ROS on Cortex-M4 provides genuine real-time ROS2 interfaces only when DDS configuration, executor scheduling, memory allocation, and interrupt priorities are designed for the specific timing requirements. A micro-ROS node jittering ±5ms is not viable for a control system requiring 1ms determinism. We design ROS2 hardware interfaces with timing as the first constraint.
