Is the Delivery cart robot 3D model free for commercial use?

Yes. It is free under the 1DesignTool 3D library license: use it in personal and commercial work — games, apps, websites, renders, ads and client projects — and modify it as you like, with no credit required. What you can't do is re-sell or re-distribute the file on its own or inside a model pack.

What file format is it, and how big is it?

A single binary glTF 2.0 file (.glb), 259 KB: 1,716 triangles, 4,132 vertices and 51 materials, modelled in metres at 78 cm × 1.3 m × 1.2 m.

Is Delivery cart robot animated?

Yes — the GLB carries a baked animation (6.0 s), ready to play with any glTF animation mixer.

Which engines and tools can open it?

Anything that reads glTF 2.0. three.js, React Three Fiber, Babylon.js, Godot 4 and Blender import the GLB directly; Unity and Unreal Engine load it through their glTF importers. The snippets above show the exact code for three.js, React Three Fiber, Godot and Blender.

How was the Delivery cart robot 3D model made?

Claude Code (Claude Opus 5.5) generated it inside 1DesignTool's 3D template from a written brief, then the design kit's checks verified the geometry and the GLB before it was published. You can make your own the same way with 1DesignTool.

Delivery cart robot

A low-poly factory delivery cart robot. A white chassis with black bumpers and a blue light strip rides on two drive wheels and four swivel casters, carrying stacked totes on a wooden pallet behind a sensor head with blue eyes and a spinning lidar. It comes with a seamless 6 s drive loop.

How it was made

The brief given to 1DesignTool's “3D object” template:

Delivery cart robot for the Robot Factory kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. It moves: author a seamless baked loop (2–12 s) with every pivot exactly at its hinge, axle or swivel, and keep the base still. This is one part of the Robot Factory kit (Low-poly style, flat-lowpoly direction): A clean line that builds robots. Use ONLY the kit palette, by name: white #f4f1ec, light grey #a3a5a8, electric blue #136dec, orange #ed7e1d, white dark #d7cebc, light grey dark #7c7f83, white light #f9f8f6, light grey light #cccccc, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `lineSpeed` (0–1, default 0.5) for the kit's "Line speed" setting wherever it makes sense on this part, and keep that id.

Note: Size: 1.19 m long (bumper to bumper), 0.75 m wide across the drive wheels and 1.28 m tall to the top of the lidar, on 0.22 m drive wheels and 0.11 m casters. The origin is at the bottom centre, the wheels rest on y = 0 and the sensor head faces +Z. The exported model has 1,716 triangles in 51 meshes. All 12 kit colours are used, and every material is named exactly after its palette colour. The exporter writes one material per mesh, so the same colour name appears on several materials: recolour by name. The baked clip scene-motion (6 s, seamless) moves only parts on their own pivots: the drive wheels roll whole turns on their axles, the casters weave on their kingpins while their wheels roll the same ground distance, the head pans on its column bearing, and the lidar and beacon spin. The chassis never moves. The export snapshots a mid-loop frame, so the glTF's static node pose (wheels, head, casters) is a frame from the clip, not t = 0. Play the clip, or seek it to 0, for the rest pose. Params are baked into the GLB at their defaults and only change the model when the scene is rebuilt in the viewer. lineSpeed (the kit's 'Line speed') sets how many whole turns per loop the wheels (1–3) and the lidar and beacon (2–6) make, so the loop stays seamless at any value. length stretches the chassis, deck and cargo bay, and toteCount stacks 1–3 totes (the push handle rises to clear 3). glb-lint: 0 errors and 5 heuristic warnings. Two are about material count and duplicate materials, both caused by the per-mesh materials. One flags non-indexed geometry, which is deliberate flat shading. One flags overlaps where trim, lights and bezels are deliberately embedded in the chassis and head. The last flags 'detached' parts, which are parts that sit on the chassis from another group. Its verdict reads UNVERIFIED only because no host requirements contract was supplied. plan-check passes except for its part-id regex, which rejects the hyphens in the slug-based ids this library requires. three-check accepts those ids, and all 20 survive the GLB reload.
