Workplace Safety

Autonomous mobile robots and AGVs, robot arms and cells, gantries and positioning stages, automated tools and test equipment, and cranes and heavy machinery. We build new designs and retrofit existing machines with sensing, connectivity and safety.

Yes. CRATUS also offers industrial and mechanical design and prototyping, so the electronics are designed together with the enclosure, thermal path and cable routing. You work with one Team-in-a-Box instead of three vendors.

BLDC and PMSM, stepper and brushed DC motors, plus solenoids, valves, grippers, linear actuators and brakes. We cover everything from low-voltage battery systems to higher-voltage industrial drives, scoped per project.

With wireless CAN. The INTERCAL8 ICL8-WC182 combines dual CAN FD channels, dual wireless links, 9–36 V input, galvanic isolation, ESD protection, an industrial temperature rating, hardware node addressing and OTA firmware updates on one board. It replaces separate gateways, radios, power supplies and protocol bridges.

Power still needs a path across the joint, so we design that too: a power-only slip ring, inductive power transfer or a local battery.

With clamps and TVS protection sized to the load, brake-chopper dissipation or regeneration back into the battery, DC-bus capacitor sizing and over-voltage monitoring. For switched loads, the LOMA ICL8-LC574’s channels are inductive-load protected.

Yes. We implement FOC with space-vector PWM using encoders, Hall sensors or resolvers, or sensorless observers when cost or packaging require it. We tune current-loop bandwidth to your motor and load, and provide tuning tools so your team can adjust gains in the field.

Current loops run in hardware-timed interrupts on Arm Cortex-M class MCUs, or on a DSP or FPGA when the bandwidth calls for it. Communications and UI run on a separate core or processor. We measure loop jitter and latency on real hardware.

We implement drive safety functions in line with IEC 61800-5-2. Safe Torque Off (STO) removes gate-drive energy through an independent hardware path. SS1 and SS2 bring the axis to a monitored, controlled stop, then either remove torque or supervise standstill. Brakes are controlled and tested. See our Functional Safety & Failsafe Electronics page for the full approach.

Yes. We write ROS 2 drivers and nodes for custom hardware, bridge CAN and CAN FD networks into ROS 2 topics, integrate navigation and manipulation stacks, and set up simulation so software can be tested before the hardware is ready.

Yes. We add sensors and telemetry gateways and connect them through ASSET-Rx EDGE, CRATUS’s no-code/low-code edge middleware. You get dashboards and alerts for utilization, faults and maintenance.

Three places. Perception detects people, vehicles and obstacles from LiDAR and cameras on Jetson-class hardware. Predictive maintenance uses motor-current signatures, vibration and temperature. Anomaly detection watches cycle times and forces. CRATUS also builds the annotated and ground-truth datasets these models need.

No. Protective stops rely on safety-rated sensors, such as safety-rated LiDAR, and deterministic logic. AI makes the machine more productive around that, for example by anticipating path conflicts and slowing early so the protective stop is rarely needed.

Yes. The INTERCAL8 AI Assistant lets operators query and manage LOMA power hardware in natural language. For example, they can see which loads are drawing the most or shed non-critical loads during peak demand.

Send us a message through our contact form with what you’re building, where it will operate and your timeline. We’ll schedule a technical discovery call, then send a scoped, phased proposal, so you can begin with an architecture study or prototype and commit to production later.

Yes. We can own the whole system as a Team-in-a-Box, or take a defined piece (the power stage, the firmware, the cloud pipeline, the AI model) and work inside your repositories, toolchains and design reviews.

Yes. We carry designs from prototype through DFM and DFT reviews, test-fixture and end-of-line test development, pilot builds and full-scale production support.

Yes. Many projects start with a bench demonstrator or a single retrofitted machine. That de-risks the control approach and the business case before you commit to a production design.
