Electronics Engineering for Next-Generation Robotics
Robotics systems demand electronics that operate flawlessly under dynamic mechanical loads, electromagnetic interference, and stringent timing constraints. At Specto Silicon, we design custom PCBs and embedded platforms purpose-built for robotic applications — from compact six-axis arm controllers to large-scale autonomous ground vehicles.
Our team understands that robotics electronics sit at the intersection of power, signal integrity, and real-time computation. Every board we deliver is designed to meet the thermal, vibration, and latency requirements unique to your robotic platform.
Motor Controllers & Drive Electronics
We design high-performance motor drive boards for BLDC, stepper, and servo motors used across robotic joints and actuators. Our motor controller designs incorporate field-oriented control (FOC) algorithms, integrated current sensing, regenerative braking circuitry, and thermal management strategies that keep drives operating within safe limits even during continuous duty cycles. We work with gate driver topologies for SiC and GaN FETs to maximise switching efficiency in compact form factors.
Sensor Fusion Platforms
Modern robotic systems rely on simultaneous data from LiDAR, IMUs, encoders, force-torque sensors, depth cameras, and ultrasonic arrays. We architect sensor fusion boards that aggregate heterogeneous sensor inputs over SPI, I2C, UART, and Ethernet interfaces, synchronise timestamps to microsecond resolution, and pre-process data before feeding it to the main compute unit. Our designs support ROS 2 middleware integration through standardised message formats and DDS-compatible transport layers.
Real-Time Control Systems
Deterministic control loops are non-negotiable in robotics. We design control electronics around Cortex-R and Cortex-M microcontrollers, FPGAs, and heterogeneous SoCs that guarantee sub-millisecond loop times. Our boards include dedicated timing hardware, watchdog circuits, and failsafe shutdown paths that comply with functional safety standards such as IEC 61508 SIL-2 for industrial robots and ISO 13849 for collaborative robots operating alongside human workers.
Autonomous Navigation Electronics
For mobile robots, AGVs, and unmanned ground vehicles, we design navigation compute boards that interface with GNSS receivers, wheel odometry encoders, and vision systems. Our boards handle SLAM processing, path planning acceleration, and obstacle avoidance decision-making. We incorporate multi-constellation GNSS with RTK correction inputs, as well as inertial navigation fallback for GPS-denied environments such as warehouses and underground facilities.
Ruggedised Interconnects & High-Reliability Design
Robotic electronics face constant vibration, shock, and thermal cycling. We specify connectors rated for thousands of mating cycles, use conformal coating and potting where appropriate, and design PCBs with strain-relief features around critical solder joints. For military and space robotics applications, we follow IPC Class 3 fabrication standards, HALT/HASS testing protocols, and component derating guidelines to ensure long operational lifetimes in unforgiving environments.
Why Robotics Electronics Require Specialised Expertise
Robotics presents a unique combination of engineering challenges that generic electronics design cannot address. High-current motor drives must coexist on the same board as sensitive analog sensor inputs without crosstalk. Power supply architectures must handle sudden load transients when actuators engage. Communication buses must maintain data integrity under severe EMI from switching power stages. And all of this must fit within the tight volume and weight budgets that robotic enclosures impose.
At Specto Silicon, we bring deep domain knowledge in mixed-signal PCB layout, power integrity analysis, and real-time embedded systems — the exact disciplines that robotics electronics demand. We have delivered boards for collaborative robots, agricultural automation platforms, underwater ROVs, and warehouse logistics systems.
