Engineering Reality.
SRQ Robotics is a single senior team that takes a device from idea to production: electronics, firmware, the math that makes sensors trustworthy, the apps and dashboards around them, and managed manufacturing. Below are the six things we do. Most clients use several together.
PCB Design
From compact wearables to RF and industrial boards, we design clean, manufacturable PCBs. Our first version usually works, saving you respins and months.
Core Capabilities
- Multilayer and HDI layout
- RF and antenna design (BLE, sub-GHz, GPS)
- Controlled-impedance and low-noise routing
- Ultra-compact and flex
- High-current power design
- Design for manufacture and assembly
Proven Result
“A 10 mm x 10 mm board integrating GPS, radio, and an MCU; a 4-layer wearable at 15 x 25 mm; a ~5 um-accurate industrial controller.”
Embedded & IoT
We build reliable firmware on Nordic nRF, ESP32, and STM32, and we are obsessive about power, ensuring devices run for months on a tiny battery.
Core Capabilities
- BLE and sub-GHz wireless
- Ultra-low-power firmware and microampere budgets
- Custom drivers and sensor integration
- Real-time control
- OTA and provisioning
Proven Result
“A tracker transmitting 2-3 times a minute for ~30 hours on a 60 mAh cell; a single-MCU drone flight controller running comms and control together.”
Sensor Fusion & DSP
The hard part is rarely the sensor; it is the math. We turn noisy, cheap parts into precise, stable measurements.
Core Capabilities
- Kalman, Extended Kalman, Madgwick, and Mahony filtering
- Multi-sensor fusion
- FFT and frequency-domain noise analysis
- Bias and drift compensation
- MATLAB modeling ported to optimized embedded C++
Proven Result
“Sub-degree rotational sensing (0.5-60 deg/s) from commodity IMUs in a magnetically noisy, swinging environment.”
Mobile Apps
The device is only half the product. We build the iOS and Android apps that pair, stream, and visualize your device's data.
Core Capabilities
- BLE connectivity
- Real-time data and charts
- Device setup and OTA
- Cross-platform (Flutter / React Native) and native
Proven Result
“BLE apps for fitness and motion-tracking wearables with live metrics.”
Full-Stack & Dashboards
When your fleet of devices needs a home, we build the back-end and the dashboards to monitor, manage, and analyze them.
Core Capabilities
- Web dashboards
- Device data pipelines
- Multi-node monitoring
- APIs and back-ends (Node, React)
Proven Result
“A multi-node monitoring dashboard for a large-scale agricultural sensor network.”
Simulations
We model, simulate, and prove out algorithms and filters first, so the hardware phase starts from a known-good design.
Core Capabilities
- Mathematical modeling
- Digital filter design
- Algorithm simulation and visualization
- Data analysis
Proven Result
“MATLAB-first development of fusion and control algorithms, then optimized for the target MCU.”
