products · the modular stack

Hardware that composes.

One real-time EtherCAT bus, one control API. Motion, power, sensing and batteries, designed to snap together into a complete robot, or to drop into yours.

01 co:act

Integrated actuators.

Quasi-direct-drive actuators with the motion controller built in. One housing, one EtherCAT node, ready to bolt into a joint.

co:act 60 mm · 420 g Coming soon

Drive

Quasi-direct drive with a hollow shaft and a 16:1 reduction ratio.

Torque

10 Nm continuous, 25 Nm peak.

Form factor

60 mm diameter at 420 g. Multiple sizes coming soon.

Dual encoder

Motor-side and output-side position out of the box.

Controller built in

Everything from the co:motion board: real-time EtherCAT, BiSS, SSI, SPI, Hall and incremental encoders, simultaneous torque, velocity and position control, and safe stopping.

02 co:motion

Motion controllers.

Real-time EtherCAT motion controllers for high-performance joint control. Deterministic loops, rich feedback, and safety where it matters.

Bus & timing

EtherCAT for 1 kHz+ real-time communication with distributed clocks.

Mechanical fit

Multiple sizes with hollow-shaft options for straightforward integration into robotic joints.

Feedback interfaces

BiSS, SSI, SPI, Hall, and incremental encoders, on- or off-axis configurations.

Motion modes

Simultaneous control of torque, velocity, and position.

Safe stopping

Controlled braking for safe emergency stopping. A Safe Torque Off module is coming.

03 co:power

A modular power system.

Precharge, regulate, dump and supervise. On a motherboard you configure. Pay only for the topology you need.

    Motherboard
    Configurable backplane
    Carries and interconnects co:system power submodules. Customizable for your system topology.

Composable

Up to 6 submodules. Stack only what the robot needs.

Native on the bus

Every submodule reports telemetry over EtherCAT. Same clock as motion and sensing.

Custom motherboards

Custom mechanical and electrical variants for your platform, on request.

04 co:sense

Sensing, synchronized.

A compact EtherCAT 9-axis AHRS for precise orientation estimation. Dual-redundant sensing, on-board fusion, and hardware time-stamping on the bus so fusion and control share one clock. More sensor modalities on the way.

Sensing core

9-axis dual-redundant IMU.

Real-time link

EtherCAT for 1 kHz+ communication with distributed clocks.

On-board fusion

1 kHz state-of-the-art sensor fusion on the module.

Outputs

Quaternion, linear acceleration, angular velocity, and magnetic field.

Footprint

30 × 50 mm. Built to tuck into tight spaces.

05 co:battery

Robot-ready battery packs.

Fully integrated batteries for your next robot. Onboard protection, state-of-charge indication, and mechanical integration that matches the rest of co:system.
