Closed beta · invites rolling out summer 2026

Describe a robot.
Get a manufacturable assembly.

RoboticsCAD turns a sentence into a validated mechanical design — geometry, parts list, and ready-to-print CAD files. No CAD software, no FEA license, no manual sourcing.

No spam. One invite email when the beta opens.

Browser-based, no install STEP · STL · URDF export ROS / Gazebo compatible
What it does

The mechanical design loop, in a single conversation.

Stop juggling CAD, simulation, BOM spreadsheets, and procurement tabs. One agent handles the engineering chain end-to-end.

Validated assemblies, not concept art

Every design passes physics-aware checks for torque, clearance, stability, and ground reach before you see it. If the math doesn't hold, the agent retries — quietly — until it does.

Real components, not placeholder boxes

The agent picks motors, servos, bearings, and structural parts from an actual parts library — with proper bolt patterns, shaft sizes, and mounting holes baked into the geometry.

Files you can actually use

STEP for CAD, STL for 3D printing, URDF for ROS and Gazebo, plus a bill of materials with the exact part numbers chosen. Hand it to a print farm or a machine shop and it works.

Conversational, not a 200-parameter form

Tell it what you need in plain language and iterate in chat: "make the reach longer," "swap to a 24 V supply," "add a gripper." It re-runs the engineering chain and shows you what changed.

How it works

From a sentence to a downloadable assembly.

Describe what you want

"A 4-DOF arm with 300 mm reach for a 200 g payload, running on 12 V." That's it — no template picker, no parameter spreadsheet.

The agent designs & verifies

Selects components, sizes the structure, lays out the kinematic chain, and runs engineering checks. You watch the steps stream in real time.

Download & build

Get .step, .stl, and .urdf for every part, plus a parts list. Print the housings, simulate in ROS, assemble.

Robots supported

One agent, four robot domains today.

Each domain has its own engineering rules — the agent knows the difference.

Robotic arms

2–6 DOF serial arms with joints, links, end-effector flanges and ROS-ready URDFs.

Drones

Quad & hex multirotors sized by payload, prop, and target flight time.

ROVs / AUVs

Pressure-rated underwater vehicles with thruster layout and buoyancy budgeting.

Rovers

Differential and skid-steer rovers with drivetrain, chassis, and clearance checks.

Coming soon

The beta opens in waves.

Builders, robotics teams, and educators are getting access first. Drop your email and we'll send you an invite when your wave is up.
