The prompt
Design a detailed, functional 6-axis industrial robotic arm in 3D CAD. **Design requirements:** - Create a robot arm with 6 rotational joints (6 degrees of freedom). - Include a solid base with mounting holes for bolting it to a workbench. - Add a rotating shoulder joint, upper arm, elbow joint, forearm, wrist assembly, and a two-finger gripper. - Use realistic mechanical components, including cylindrical joint housings, motor mounts, bearing housings, shafts, brackets, and connecting links. - Add mounting flanges and bolt holes at the joints. - Design the gripper with two parallel fingers that can open and close. - Make each major component a separate solid body so the model can be assembled and edited. - Use realistic proportions: approximately 500 mm total reach and a 150 mm base diameter. - Use suitable wall thicknesses and mechanical clearances for a prototype. - Avoid unnecessary decorative details; prioritize mechanical functionality and manufacturability. - Ensure that the joints are aligned correctly and that the parts do not intersect during assembly. - Use millimeters as the unit system. - Create a clean, organized CAD model suitable for further development in a CAD application. - Export the model in STEP format for CAD editing and STL format for 3D printing. **Important:** This is a conceptual CAD design. Do not assume the model is ready to carry loads or operate safely without engineering validation.
