open-source build catalog

CAD, controls, and interface assets for managed automation cells.

A single catalog of robotics, CNC, vision, conveyors, grippers, simulators, CAD tools, and open interface layers that can seed Mattergrid demos, starter cells, data adapters, and the module marketplace. All ranges are in Indian rupees. They are directional Indian-market estimates for early prototypes and first customer pilots, before taxes, freight, duties, site work, and formal safety certification.

Robot Cell

Universal Robots ROS 2 Description + Driver

fit A

format

URDF / meshes / ROS 2 driver

viewer

Animated CAD preview mapped to the primitive type.

Industrial robot cell simulation, driver integration, Gazebo demos, MoveIt planning.

India prototype

Rs. 18L-45L

India pilot

Rs. 45L-90L

India sourcing list

UR cobot or used/partner demo arm, safety scanner, pedestal, EOAT, controller cabinet, camera or part sensor.

CAD to real route

Use URDF/meshes for simulation; outsource only brackets, fingers, guards, and fixtures to CNC or SLS/MJF printing.

Industrial robot hardware dominates cost; CAD fabrication is a smaller fixture/tooling layer.

engineering note

Best as a simulator and integration reference unless the customer actually uses UR hardware.

next build step

Replace previews with live model viewers as assets are imported.

The current page makes the catalog easy to scan. The natural next layer is loading STEP, STL, URDF, or mesh files into a Three.js viewer per asset, with module metadata attached to every model.
