Industrial Robotic Arm Torque Controller
Industrial Robotic Arm Torque Controller with Arduino Portenta H7 – Real-Time FOC and Trajectory Safety
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
What if every joint in your robotic arm could react to load changes in microseconds, maintaining precise torque while a separate core enforces position limits and trajectory smoothness? This kit lets you engineer exactly that – a production-grade single-axis controller where the Portenta H7’s M7 core runs field‑oriented control (FOC) on a BLDC motor at 20kHz, while the M4 core simultaneously handles trajectory planning, safety interlocks, and user commands without missing a single encoder pulse.
What You'll Build
You will assemble a fully enclosed torque controller that drives a 2204 brushless motor with closed-loop current and position feedback. The final unit accepts high-level position/torque commands and executes them safely, making it the building block for industrial robot joints, CNC spindles, or automated test rigs. You’ll get a functional controller that mounts on a standard DIN rail and communicates status over an OLED display and serial interface.
What You'll Learn
- Implementing field-oriented control (FOC) on the Arduino Portenta H7’s M7 core at a 20kHz loop rate
- Partitioning tasks between dual cores: M4 for trajectory generation, safety monitoring, and communication
- Interfacing hall-effect encoder (AS5600) and current sensor (INA219) for closed‑loop feedback
- Designing safety limits for torque, position, and velocity directly in firmware using the M4 core

Who This Kit Is For
Engineered for final-year B.Tech (ECE/EEE/Mechatronics) students, robotics researchers at IIT/NIT/VIT/BITS, and industry professionals prototyping industrial automation solutions. If you're tackling Smart India Hackathon hardware challenges or building a proof‑of‑concept for a multi‑axis arm, this kit gives you the dual‑core architecture that commercial controllers rely on.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box for an AI companion pre‑trained on this project, or reach us on WhatsApp for direct engineer support within 24 hours.
Can I use this controller for a multi-axis robotic arm?
This kit builds a single‑axis torque controller. For multi‑axis applications, you can replicate the hardware and synchronize multiple Portenta H7 boards via CAN bus – the dual‑core architecture isolates each joint’s real‑time control.
Do I need prior experience with SimpleFOC?
No. The kit includes the complete SimpleFOC library pre‑configured for this hardware. The AI companion walks you through tuning the PID loops and setting up the M4 trajectory planner.
What is the role of the dual-core processor in this design?
The M7 core runs the FOC torque loop at 20kHz with no interruptions. The M4 core independently handles trajectory generation, safety limits, OLED updates, and communication – so you get deterministic real‑time control without overloading a single core.
M7 runs FOC torque control on BLDC at 20kHz via SimpleFOC. M4 handles trajectory planning and safety limits.
