Robotics hardware — Dallas, TexasCatalog rev. 2026.10

Built as nodes. Measured like instruments.

Motor, sensing and sync nodes on one USB-C bus. Makers use them one at a time, robotics companies build them in, and our data-station hardware is assembled from them.

03System

One cable per device.

Each node’s own USB-C port is the bus: power negotiated over PD, USB to a computer, and CAN to everything else. On a bench, a phone charger runs one node. On a floor, a Hub 8 Pro runs eight.

Fig. 02 — Bus topology. Hub 8 Pro ports are point-to-point segments, so a damaged cable is cut off without stopping the others.

04Test card

Every unit ships with its own numbers.

Each node is calibrated and measured at final test, and the results go in the box and stay on the node. We publish measured values. Anything we haven’t measured yet is marked as a target.

  • Encoder calibration stored on the node, not in a laptop’s config file
  • Backlash, backdrive and torque recorded per serial number
  • The same record goes to makers, OEM customers and our own stations

Our station hardware is made of this catalog.

A floor’s spare part is a node from the index above, and a repair is a swap. Each system below is a list of catalog numbers plus a little structure.
