Units typically measure 3.4–4.1 meters shoulder height and consume 1.8–2.4 kW/hour during operational cycles lasting 6–12 minutes. Current models carry ≈350,000 unit cost but demonstrate >85% 5-year reliability with monthly maintenance budgets averaging 1,200–$2,500.

The trunk mechanism features 18 modular aluminum segments driven by 12 servo motors achieving horizontal oscillation velocities of 0.15–0.35 m/s and vertical lift capacity up to 250 kg. Water propulsion systems integrate variable-flow pumps moving ≈75 liters/minute through thermostatically controlled (32°C±2°C) reservoirs, creating mist effects with 20–50 micron particle distribution at 1.3 bar pressure. For locomotion, base platforms weighing 1,800–2,400 kg utilize electro-hydrostatic actuators enabling directional changes at ≤2.5 seconds response time with pivot precision within ±1.8° angular tolerance.

Energy consumption profiles vary significantly by activity: static trunk sway requires only 0.9 kW/hour, while simultaneous walking and spraying peaks at 3.4 kW/hour. Thermal management remains critical, as hydraulic reservoirs must remain between 55–70°C via 8-finned heat exchangers dissipating ≥28,000 BTU/hour.

Endurance testing confirms 18,000+ climbing cycles before joint rebuilds, enabled by accelerometer-triggered safety cutoffs that engage when vibration frequencies exceed 120 Hz nominal thresholds or loads surpass 150% rated capacity, automatically switching to auxiliary braking systems providing ≤25cm/sec controlled descent.

Artificial terrains integrate 64-point weight-distribution sensors detecting visitor proximity within 1.2-meter radius, activating species-specific behavioral responses: black bear units initiate arboreal climbing at 35-second intervals (±3s variance) with 27 cm average reach extension, while grizzly animatronics trigger "fishing" simulations using magnetized paw assemblies lifting 4.8kg salmon replicas against programmable water currents flowing at 0.6–1.1 m/s. Power systems compensate for these variable demands – energy-recapturing hydraulics during descent sequences reduce net consumption to 0.9 kW/hour during standby versus 3.2 kW/hour during active climbing routines.
