PROCEDURAL ROBOT ARMS

PICK A MODEL, PRESS ADD

Pick an arm in the gallery and press Add. Everything else stays in the side panel while it moves.

• Six arms: industrial, hydraulic, hobby kit, sci-fi gold, boom rover and cobot
• Five tools: two-finger, three-jaw, linkage, geared and vacuum, all with working mechanisms
• IK or FK: move one target and the tool follows, or set the six joints by hand
• Grab and Release: one press picks an object up, another sets it down, keyed for you
• Status lights: green idle, amber holding, red when the target is out of reach
• Dimensions: link lengths, thickness, base and tool size, all keyframable
• Dampers and cables: hydraulic cylinders and a harness that follow every move
• Materials: ten shared slots, colour presets, wear, dirt and worn edges
• Bake to Parts: a named mesh hierarchy for export to other software

ONE TARGET, ONE PRESS TO GRAB

Two arms, one crate: the Industrial sets it on the middle stand and the RX Cobot carries it on. Each move is an IK Target key and a press of GRAB or RELEASE, rendered in Cycles.

PICK ONE, PRESS ADD

The gallery shows all six: Industrial, Veteran Hydraulic, Bracket Kit, Aurum, Boom Rover and RX Cobot. Pick one, press Add, and it lands at the 3D cursor with real proportions, its own colours, a default tool and joint limits.

INDUSTRIAL TO HOBBY KIT

Each one loads with its own tool, colours and pose. Add as many as the scene needs; each gets its own target and materials.

ONE SLIDER CLOSES THE GRIP

The Tool menu swaps the end effector and Grip closes it. Lead screws, linkages, meshing gears and knuckles move as the jaws close, so a close-up holds up.

OPEN AND CLOSED

Two-Finger Gripper, Three-Jaw Claw, Linkage Claw, Geared Gripper and Vacuum Suction. Frames sets how many frames a grab takes to close.

RED WHEN IT CAN'T REACH

Set the six joints in FK, or switch to IK, press Select IK Target and move it: the tool tip follows. Pull it too far and the panel says by how much while the status light turns red; Target to Tool Tip brings it back and Rest Pose resets the arm.

PUT THE TOOL ON IT, PRESS GRAB

Pick the object in Target (or select it), bring the tool to it and press GRAB: the jaws close to fit it over the Frames before, and it rides along until RELEASE. Every step is keyed, so it plays back.

LONGER, THICKER, TALLER

Upper arm, forearm, wrist, thickness, base height and tool size rebuild the whole arm, cables and dampers included. Key them for telescoping parts. After changing them, press Target to Tool Tip so the IK target sits on the new tip.

HYDRAULICS THAT STROKE

Cables on or off, more strands, thicker or slacker; bolts, status lights and both dampers switch on their own, and the label takes your text. Cylinders with lug eyes and pins stroke as the arm moves.

LIGHTS AND YOUR LABEL

The Status Lights show what the arm is doing: green at rest, amber while it holds something, red when the target is out of reach. The Label puts your own text on the nameplate.

PRESETS, THEN MAKE IT YOURS

Pick a colour preset or Randomize Look, then edit any of the ten materials in the Shader Editor: Wear, Edge Wear and Dirt are inputs on each.

CHIPS, SCRATCHES, WORN EDGES

Every material is one RA Surface node in the Shader Editor. Raise Wear for chipped paint, change Texture Scale for big chips or fine speckle, and Edge Wear to bare the edges, all live in Cycles.

ONE OBJECT, ANY ENGINE

Each arm is one object with a Geometry Nodes modifier, so it renders in EEVEE and Cycles with Python auto-run off. Parts carry UV maps, and Bake to Parts splits the arm into a named, parented mesh hierarchy for export.
