Design three interlocking gears that rotate together.

Do NOT include any base plate or panel.
Only model the gears and their rotational relationship.

Rounded teeth for child safety.
Smooth rotation suitable for 3D printing.

The model must be modular and ready to be embedded into another surface.

Base Rotation Joint

A sturdy circular base.

Includes a primary rotational servo joint allowing the entire arm to rotate horizontally (0–360°).

First Linear Hydraulic Actuator

Mounted on the rotating base.

Provides vertical lift to the first main arm segment.

Should look like a realistic hydraulic cylinder (piston + sleeve + fittings).

Second Linear Hydraulic Actuator

Connected between the first arm segment and the second arm segment.

Controls the mid-arm extension and angle.

Use realistic hydraulic hoses, joints, and pin connections.

Third Linear Hydraulic Actuator

Controls the wrist-level lift or tilt.

Mounted between the second arm segment and the wrist section.

Include hydraulic lines and brackets.

Fourth Linear Hydraulic Actuator

Controls the orientation of the claw mount (tilting forward/backward).

Positioned at the end of the wrist section.

Fifth Linear Hydraulic Actuator (Claw Control)

Directly connected to the claw mechanism.

When the actuator extends, the claw opens; when it retra

---1) Basic specifications (feasible)Transverse manned model (executive example of presentation/working model):Radius of rotation axis (from rotation axis to seat center): r = 2.0 metersRequired to generate 1 g at this radius: Calculation of ω and RPM:1. Central acceleration law where .2. .3. Conversion to cycles/minute: .Practically, for comfort and to reduce dizziness, I recommend an operating range of 0.3g — 1.0g (meaning RPM from ~11 to ~21).Larger full model (suitable for small human testing or study):Radius r = 4.0 m → RPM ≈ 15.0 RPM to produce 1 g (calculations: ω = 1.566 rad/s → RPM ≈ 14.95).Miniature model for exhibition/3D printing (scale 1:4):Use r = 0.5 m → RPM ≈ 34–35 RPM to produce 1 g (useful for display but not for humans).---2) General shape and structure (engineering detail)External structure: Ring frame mounted on two arches on two vertical axes (like a turntable on large bearings). Cross-sectional design: Cross-sectional ring like a rectangular pipe section to provide rotational rigidity.

„Design a minimalist, 3D-printable vase inspired by a twisted high-rise tower structure. Reduce the concept to a clean, symmetrical base geometry with a smooth rotational twist along the vertical axis (max. 10–20 degrees total twist). The form should be derived from stacked, slightly offset circular or polygonal sections that gradually rotate and align into a coherent silhouette.
Avoid surface complexity, ornamentation, or perforations. Emphasize structural clarity, printability, and continuous wall thickness (2–4 mm). Ensure the vase has a stable flat base, a smooth internal cavity suitable for water, and a gently narrowing neck.
The final design should feel architectural but simplified—like a parametric interpretation of a twisted tower reduced to its core geometric transformation. Matte, monolithic appearance, no texture.”
