More Than Service Providers - We Are Design Partners
H4 Lab’s team has a long history of deep collaboration with leading hardware and software robotic companies. Located in Montreal, our experienced team takes ownership of hardware challenges through continuous communication, rapid iteration, and on-site debugging. We bring expertise in physical AI hardware so your team can focus on what they do best.
Our expertise
Humanoid Robotics System Design
Developing humanoid platforms requires a deep understanding of power dynamics and mechanical constraint. Drawing on years of hands-on experience helping partners build and scale complex humanoid hardware, we provide full system-level electrical and network architecture.
Whole-Body Power Distribution: Designing safe, high-efficiency power networks capable of handling massive transient currents from high-torque motors.
Deterministic EtherCAT Architecture: Designing robust internal communication backbones utilizing EtherCAT to connect dozens of sensors and actuators, managing master/slave interfacing to eliminate latency bottlenecks.
Subsystem Integration: Packaging complex electronics and high-density communication routing into tight, mechanically constrained structural frames and moving joints.
Expert Electrical & Embedded Firmware Design
We deliver production-ready, rugged, and high-density PCBAs engineered for demanding environments. Our engagement is entirely modular: we can design the hardware and write the low-level code concurrently for a turnkey solution, or focus strictly on the electronics and deliver clean, bring-up-ready boards to your internal software team.
Power Electronics & Custom Drivers: Custom motor drives, battery management systems, and power regulation optimized for high efficiency and low-level safety-critical protection.
Custom EtherCAT Slave Development: Designing specialty EtherCAT communication cards and custom slave devices, with the ability to integrate custom low-level slave firmware stacks tailored to your specific application.
Complex, High-Density PCB Design: Advanced multi-layer and rigid-flex layouts engineered for complex geometries and high-noise environments. We deliver fully brought-up hardware, with the option to include custom firmware for high-frequency sensor integration (IMUs, force-torque, encoders) depending on your requirements.

Client Success Story
Next-Generation Robotics with IHMC
H4 Lab and the Institute for Human and Machine Cognition (IHMC) collaborate to develop the hardware infrastructure for IHMC's next-generation robotic platform.
Together, we combine expertise in system architecture, high-power electronics, and deterministic communication networks to transform ambitious robotic concepts into rugged, production-ready systems.
What We Delivered:
System Design & Electrical Architecture: Collaborated at the foundational level to map out the robot’s overall electrical and network framework, ensuring seamless interoperability and safety across all subsystems.
Power Management Board: Designed and developed the core power management hardware and low-level firmware to handle complex power sequencing, transient currents, and distribution for the entire platform.
Motor Control Carrier Boards: Engineered high-density, rugged carrier boards optimized for high-performance actuation and tight structural integration within the robot's limbs.
EtherCAT Communication Boards: Developed custom, ultra-low-latency communication hardware to ensure reliable, deterministic, real-time data flow across the robot's high-degree-of-freedom architecture.
Research and Developpement
Turning ambitious ideas into proven technology.
Our R&D services include feasibility studies, proof-of-concept development, technology evaluation, prototype design, experimental validation, and performance characterization. We work closely with industrial partners, startups, and research organizations to bridge the gap between cutting-edge research and deployable products.
Some challenges require more than engineering execution. They require exploration, experimentation, and innovation. H4 Lab partners with clients on research and development projects to evaluate new technologies, de-risk ambitious concepts, and develop novel hardware solutions.
With multiple PhDs from prestigious institutions within our team members, whether it is advancing the state of robotic sensing, power electronics, embedded systems, or communication architectures, we can partner and support with your organization.
