Custom PCBs
Purpose-built boards for industrial robots — sensor interface, power distribution, isolated fieldbus and compute carriers. Designed for the temperature, vibration and EMC realities of a plant floor.
00Physical AI
Hardware-agnostic software and drivers for industrial robots.
We design custom PCBs for humanoid, land and aerial robots, and pair them with a driver layer that speaks to standardized industrial sensors — whichever OEM they come from. One API. Any hardware. Industrial grade only.

01What we do
Three things, done to industrial standard.
Robot builders lose months writing glue code for sensors and re-spinning boards for every new platform. We remove both problems.
Hardware-agnostic driver layer
One API across sensor vendors. Swap a LiDAR, encoder or force-torque unit for another OEM's part and your application code does not change. We take the standard drivers OEMs ship and normalize them.
Industrial sensor integration
We integrate standardized industrial sensors only — no hobby-grade parts. We work with the industrial OEM ecosystem so the sensors on your robot are the same class as the ones on the line beside it.
02Platform
The stack, top to bottom.
Your autonomy code sits on top. Everything below it is ours to keep stable while the hardware underneath keeps changing.
-
L5
your code
Robot application
Perception, navigation, manipulation, autonomy, fleet logic. Untouched by hardware changes.
-
L4
hardware-agnostic API
Koira HAL
Uniform types, units, timestamps, frames and health reporting across every supported device class.
-
L3
OEM drivers, normalized
Driver layer
The standard drivers each OEM ships, wrapped, version-pinned, tested and made to behave identically.
-
L2
deterministic
Fieldbus & transport
EtherCAT, CANopen, PROFINET, IO-Link, EtherNet/IP, Modbus, TSN and deterministic Ethernet timing.
-
L1
our board
Koira PCB
Sensor front-ends, isolation, power rails, safety I/O and an edge-compute carrier on one board.
-
L0
OEM
Industrial sensors & actuators
Standardized industrial parts from the OEM ecosystem. Interchangeable by design.
Swap without a rewrite
Change vendor at L0 and nothing above L3 moves. Procurement stops being an engineering event.
Deterministic by default
Real-time scheduling, bounded jitter and synchronized timestamps across every sensor on the bus.
Built to be audited
Version-pinned drivers, traceable board revisions and test evidence for every supported part.
03Hardware
Boards designed for robots that have to survive a factory.
Every industrial robot programme eventually hits the same wall: the off-the-shelf carrier board cannot take the sensors, the power or the environment. We design the board around your platform instead.
- Stack-upMulti-layer and HDI, controlled impedance
- EnvironmentIndustrial temperature range, vibration and shock aware layout
- ComplianceEMC/EMI hardened, conformal-coating and IP-enclosure ready
- IsolationGalvanic isolation on fieldbus and safety I/O
- PowerPower distribution and motor-drive interfacing
- ComputeCarrier boards for common edge-AI compute modules
- ManufactureDesign for manufacture, with volume scale-up in mind
- TestBoard-level test fixtures and hardware-in-the-loop rigs
04Sensors
Standardized industrial sensors. Only.
We partner across the industrial OEM sensor ecosystem and take the standard drivers they provide. These are the device classes our driver layer covers.
| Device class | Typical devices | Interface |
|---|---|---|
| LiDAR & 3D ToF | 2D safety scanners, 3D LiDAR, time-of-flight depth | Ethernet, EtherCAT |
| IMU & AHRS | Inertial units with characterized bias stability | SPI, CAN, RS-422 |
| Encoders | Absolute and incremental, rotary and linear | EtherCAT, SSI, BiSS |
| Force–torque & load | Six-axis force-torque sensors, load cells | EtherCAT, CANopen |
| Machine vision | Industrial cameras with synchronized triggering | GigE Vision, USB3, MIPI CSI-2 |
| Functional safety | Safety scanners, light curtains, e-stop chains, STO | Safety I/O, FSoE |
| Proximity & presence | Inductive, capacitive, photoelectric, ultrasonic | IO-Link, discrete I/O |
| Radar & GNSS-RTK | All-weather radar, centimetre-grade positioning | CAN, Ethernet, UART |
| Process & power | Temperature, pressure, flow, current, voltage | IO-Link, Modbus, I²C |
05Platforms
Humanoid, land and aerial — one driver layer.
The physics differ. The sensor problem does not. Our boards and drivers target all three classes of industrial robot.
Humanoid
Dense joint sensing, force-torque at the wrists and ankles, and tight timing budgets across dozens of devices on the same bus.
Land
Quadrupeds, AMRs and tracked platforms. Outdoor perception, wheel and track odometry, and safety-rated obstacle detection.
Aerial
Inspection and survey platforms where mass budget, redundancy and certified sensor provenance all matter at once.

A sales office today. As infrastructure and legal setup complete, we grow headcount into product scale-up and testing.
India has the potential and the know-how to build this locally. We are not opening a back office here — we are moving the scale-up and the testing of our products into the country.
