| Model Size and Proportions | Small display models, life-size exhibits, and large outdoor figures are commonly available. Head, tail, body height, and stance can usually be adjusted. | Provide overall height, length, footprint, viewing distance, and the desired anatomical reference. | Dimensioned drawings, 3D renderings, weight estimate, and final approval drawings. | Confirm whether the packed dimensions fit the selected container, doorway, elevator, and installation route. |
| Exterior Appearance | Custom skin texture, color pattern, scales, armor plates, eyes, teeth, claws, and habitat effects may be specified. | Use approved reference images, color samples, surface-finish requirements, and branding restrictions. | Material samples, color chart, surface mock-up, and pre-shipment photographs or video. | Outdoor colors and coatings should be selected for the local climate and expected viewing distance. |
| Movement Programming | Common functions include head movement, jaw movement, tail motion, breathing simulation, body sway, sound synchronization, and lighting effects. | Define movement speed, operating sequence, pause intervals, sound level, and emergency stop behavior. | Motion sequence video, control-system description, operating manual, and acceptance-test checklist. | Verify compatibility with the venue schedule, visitor flow, local noise limits, and electrical frequency. |
| Control System | Local control panels, wired remotes, programmable controllers, sensor triggers, and scheduled operation are widely used. | Specify manual override, automatic mode, trigger distance, restart behavior, and access restrictions. | Wiring diagram, control-panel layout, software backup, password policy, and fault-reset procedure. | Ask for English documentation and confirm whether remote technical support is available across time zones. |
| Safety Protection | Typical provisions include emergency-stop buttons, guarded moving parts, low-voltage control circuits, overload protection, cable management, and warning labels. | Require a documented risk assessment covering pinch points, entanglement, access zones, tipping risk, and visitor interaction. | Risk assessment, electrical test report, emergency-stop test record, safety instructions, and maintenance access plan. | Final compliance requirements depend on the destination country, venue type, local authority, and installation method. |
| Structural Stability | Steel or aluminum internal frames with weighted bases, anchor plates, or foundation connections are commonly used. | Specify wind exposure, floor type, maximum visitor proximity, seismic conditions where relevant, and anchoring limitations. | Structural drawings, center-of-gravity information, anchor-bolt plan, load data, and installation method statement. | Outdoor installations may require local engineering review, wind-load calculations, drainage, and lightning protection. |
| Weather Resistance | Outdoor models may use sealed electronics, water-resistant enclosures, UV-resistant coatings, corrosion-resistant hardware, and drainage features. | State whether the model will be indoors, under cover, or fully exposed to rain, sunlight, dust, snow, or coastal air. | Material specifications, enclosure ratings where applicable, coating information, drainage details, and cleaning instructions. | Water resistance is not the same as unlimited waterproofing; installation, drainage, and routine inspections remain essential. |
| Electrical Requirements | Systems are commonly configured for the destination voltage and frequency, with dedicated circuits recommended for larger installations. | Confirm rated voltage, frequency, total power, peak starting load, plug type, cable length, and circuit protection. | Electrical schematic, power-consumption sheet, conformity documentation, and recommended breaker specification. | A qualified local electrician should verify the final connection and venue distribution-board capacity. |
| Audio and Lighting | Optional speakers, amplifiers, LED eyes, internal lighting, directional sound, and programmable effects are commonly offered. | Define maximum sound pressure, audio file format, lighting color, operating hours, and synchronization requirements. | Audio specification, lighting power data, sample media, control instructions, and replacement-part information. | Check local restrictions on noise, flashing lights, public announcements, and nighttime operation. |
| Installation Scope | Delivery may include assembly drawings, numbered components, remote guidance, on-site supervision, or full installation support. | Clarify foundation work, unloading equipment, lifting requirements, assembly time, commissioning, and staff training. | Packing list, installation manual, lifting points, method statement, commissioning report, and training record. | Allocate responsibility for customs clearance, local labor, permits, cranes, forklifts, and site preparation. |
| Packaging and Shipping | Large models are often divided into transportable sections and protected with reinforced crates or custom packing frames. | Request packed length, width, height, gross weight, number of packages, and recommended shipping conditions. | Commercial invoice, packing list, crate markings, export documents, and loading photographs. | Compare sea, air, and road options using total landed cost rather than product price alone. |
| Maintenance Program | Routine work generally includes cleaning, lubrication where specified, fastener checks, cable inspection, sensor testing, and software backup. | Require a preventive-maintenance schedule based on operating hours, environment, and visitor contact level. | Maintenance manual, lubrication chart, inspection checklist, troubleshooting guide, and recommended spare-parts list. | Confirm whether local technicians can perform routine work without voiding the warranty. |
| Spare Parts and Service | Common service items include motors, gearboxes, sensors, controllers, power supplies, cables, protective covers, and surface-repair materials. | Obtain a parts list with part numbers, prices, expected service life, and replacement procedures. | Spare-parts catalogue, service contact details, diagnostic procedure, and technical-support response terms. | Keeping critical spare parts locally can reduce downtime caused by international shipping and customs delays. |
| Warranty Coverage | Commercial warranties commonly define separate coverage for structure, mechanical parts, electronics, workmanship, and consumable or cosmetic items. | Clarify duration, start date, exclusions, labor coverage, shipping responsibility, and response time for defects. | Written warranty, exclusions, claim process, inspection procedure, and replacement or repair terms. | Confirm whether exposure to weather, unauthorized modifications, improper voltage, or incorrect installation affects coverage. |
| Quality Control and Acceptance | Pre-shipment inspection may cover appearance, movement, sound, lighting, controls, electrical safety, and package completeness. | Use measurable acceptance criteria and approve a factory test before dispatch. | Factory acceptance test, inspection photographs, test video, serial-number record, and signed punch list. | Independent inspection can be considered for high-value or public-access installations. |
| Compliance Documentation | Depending on the market, documentation may include electrical test results, material information, risk assessments, user manuals, and conformity declarations. | List the destination-country requirements before production begins and identify the responsible compliance party. | Technical file, electrical test report, safety instructions, conformity statement, and installation records. | Certificates from one jurisdiction may not automatically satisfy the requirements of another jurisdiction. |
| Customization and Change Control | Projects may be customized through approved drawings, sample reviews, prototype adjustments, and staged production approvals. | Set clear revision limits, approval milestones, tolerances, and responsibility for post-approval changes. | Quotation, specification sheet, revision-controlled drawings, change-order record, and final approval document. | Written specifications reduce disputes involving appearance, movement, color, sound, delivery scope, and installation. |
