Product engineering · Shenzhen
The engineering behind your next device.
A Shenzhen hardware team with the full stack in house: industrial design, mechanical, hardware, embedded firmware, app, server and finished production. One thing we do not do is sell finished goods — so your market stays yours.
- Hardware first
- Schematic, PCB layout, structure and tooling are ours. A software house cannot do this part.
- Four silicon tiers
- MCU through NPU-class Linux SoC, domestic and overseas parts.
- Direct vendor FAE
- Escalation reaches the people who wrote the SDK.
- Full stack in house
- ID, structure, hardware, firmware, app, server and production — one team.
Silicon coverage
Four compute tiers, no vendor lock-in
From NPU-equipped Linux application processors down to motor-control MCUs, we design across every tier these products need — on both domestic and overseas silicon. Chip selection follows your cost, supply and certification constraints, not the one part we happen to know.
Linux SoC with NPU
0.5 – 16 TOPSOn-device AI, vision and video
Application processors with an integrated NPU, 0.5 to 16 TOPS depending on what has to stay local. At the 0.5–1 TOPS end: pet and object detection, human presence and behaviour analysis, wake word and speech recognition, alongside the ISP, H.264/H.265 encode and multi-camera MIPI input. From roughly 6 TOPS a quantised small language model runs on the device, which is what an offline fallback is actually made of, and at 16 TOPS multi-stream vision and a local model can share the part. Picking the tier is a cost decision as much as a technical one — more NPU than the product uses is money spent on the datasheet.

WiFi / Bluetooth SoC
Connectivity and audio
WiFi SoCs for provisioning, streaming and cloud links; Bluetooth SoCs for BLE sensors, dual-mode and audio. These run an RTOS in a few hundred KB of RAM, so pairing reliability, OTA, power budget and the audio front-end are firmware problems rather than OS problems — and firmware is where most connected products actually fail.

MCU
Control, motors and power
Motor control, sensor sampling, charging and power sequencing. The unglamorous tier that decides whether a feeder jams, a dryer overheats, or a device wakes reliably at 2% battery.

Panel selection, driver IC bring-up, touch integration and colour calibration. Screen quality is what a retail buyer judges in three seconds, so we treat the display chain as its own discipline.

Direct vendor FAE support
We work with silicon vendors directly, not through a design house or a distributor. A stubborn bug gets escalated to the people who wrote the SDK, new parts reach us at sampling stage, and pricing has one less layer in it. On the platform side we build on Baidu AI Cloud, mainstream LLMs, speech recognition and synthesis engines, an open-source AIoT framework and audio/video cloud services, so an AI robot project can start from a working voice, IoT and large-model stack rather than from scratch.
AI robots
Where most of our AI robot work starts
Companion and in-car robots are what people bring us most often. Each page is written for the engineering, not the pitch — what runs on the device, what the response budget is, and what has to be decided before anything can be quoted.
AI companion robot ODM
Desktop and handheld companion robots: wake word and speech on the device, the language model in the cloud, servo motion, far-field audio, structure and tooling through to certification and production.
Companion robot development →In-car AI robot ODM
Automotive-context assistants: cabin noise and far-field pickup, the temperature range a dashboard actually sees, power behaviour across ignition cycles, and the mounting problem nobody budgets for.
In-car robot development →What we develop
Six directions
Sensing, on-device inference, wireless and power are the same four problems in a different housing. These are the categories our engineering is built around — each page names the part that actually decides whether a project ships.

Bring us the category
The engineering transfers. Ask, and we will tell you honestly whether we are the right team for it.
Capabilities
A hardware team that also writes the software
Most teams sit on one side of this line. A software house cannot lay out a board or cut a mould; a factory that can usually subcontracts the firmware and the app. When a device will not pair, that split is where a project stalls — each side reports their part works. Here it is one team, so the question is just what to fix.
Hardware & structure
Schematic, PCB layout, ID/MD and tooling design. DFM review before a mould is cut.
Firmware & algorithms
Low-power firmware, PPG and motion algorithms, far-field audio, on-device vision models.
App, mini program & server
iOS, Android, WeChat and Alipay mini programs, plus the cloud platform behind them — device provisioning, OTA and the admin console.
Compliance planning
We map the certification path for your market at the brief stage, so it runs alongside tooling.
Engagement
Six disciplines under one roof — take all of them, or only the ones you are missing
Most projects arrive with something already done: a design from an agency, firmware from an in-house team, an app built elsewhere. We pick up exactly where you are and hand back the rest.
- 01
Industrial design
Concept sketches, renders, CMF and the appearance model.
- 02
Mechanical design
3D structure, DFM review, tolerance stack-up, tooling and trial shots.
- 03
Hardware design
Schematic, PCB layout, RF and antenna tuning, power and thermal.
- 04
Embedded software
Drivers, RTOS or Linux, voice and AI pipelines, OTA and factory test firmware.
- 05
App & mini program
iOS and Android apps, and WeChat mini programs for the China market.
- 06
Server side
Device cloud, provisioning, OTA delivery, admin console and open APIs.
Common ways clients split the work
- Turnkey — all six, from sketch to shipped unit
- Hardware + firmware, plugged into your app and cloud
- Your design, our structure, electronics and production
- App and server side for hardware you already ship
- Production engineering and manufacturing only
