Roxbury Robotics specialises in the design, specification, and integration of Robotis Dynamixel smart servos — from benchtop articulation studies to production-grade mechatronic assemblies. We work with one actuator family. We know it deeply.
We specify and integrate across the entire Dynamixel catalogue, from the sub-gram XL-330 to the Pro Series industrial joint. Our depth in one product family is the differentiator — we don't dilute our expertise across twelve vendors.
A Dynamixel is not a servo. It is a joint, a sensor, and a protocol endpoint — in one aluminium housing.
Most hobby servos take a PWM pulse and hope. You don't know where they are, whether they got there, or how hard they had to push. You find out when something breaks — usually in a demo, usually under load.
Dynamixels return position, velocity, current, temperature, voltage, and load on every query. They accept commands in position, velocity, current, or PWM mode, switchable at runtime. Metal gears. Contactless magnetic encoders. A half-duplex bus that daisy-chains every joint onto two wires plus power.
That means fewer harnesses, cleaner firmware, and a mechatronic stack where the hard problems are the ones worth solving — not "why is joint four jittering again."
A single two-wire run services every joint in the assembly. Up to 253 addressable IDs per bus. Fewer harnesses, cleaner looms, shorter build cycles.
Position, velocity, current, input voltage, internal temperature, present load — every field, every joint, on demand or in continuous sync.
Switch between position, velocity, current, and PWM control at runtime. Per joint, per millisecond. No reflashing, no external drivers, no compromise.
Broadcast a coordinated motion command to every joint in a single packet. All setpoints land on the same millisecond edge. No drift.
Real spec sheets. Real torque curves. Metal-geared from the XL-330 up through the Pro Series harmonic drive. No hobby-servo lottery.
DynamixelSDK covers C, C++, Python, .NET, and Arduino. First-class ROS 1 and ROS 2 packages. Dynamixel Wizard for tuning without code.
Half-duplex serial. A single master, up to 253 peripheral IDs, all sharing the same bus and the same packet format. Whether it's TTL, RS485, or CAN at the physical layer, the API above it is identical.
