Intelligent Amphibious Spherical Robot - Rotunbot

Rotunbot RT-G800 Intelligent Amphibious Spherical Robot

The Rotunbot RT-G800 is a next-generation intelligent amphibious spherical robot designed for long-duration operations in complex terrain, extreme weather, and non-friendly environments. Built around a unique spherical contour and centroid offset drive system, Rotunbot represents a breakthrough in unmanned ground robotics, offering unmatched stability, endurance, and all-weather operational capability where conventional wheeled or legged robots fail.

Engineered for demanding applications such as civil aviation airports, public security, armed police operations, energy infrastructure inspection, and emergency response, the RT-G800 delivers a reliable, autonomous solution for continuous patrol, monitoring, and intervention tasks. Its sealed spherical design, high-speed rolling mobility, and advanced sensor fusion allow it to operate safely in rain, snow, sand, fog, extreme temperatures, and hazardous environments with minimal human risk.

Revolutionary Spherical Mobility and Drive Architecture

At the core of the Rotunbot RT-G800 is its patented spherical structure combined with pendulum-based centroid offset drive technology. Three internal motors drive a pendulum mechanism that shifts the robot’s center of mass, generating rolling torque in any direction.

This design fundamentally eliminates common failure points seen in wheeled and legged robots, such as tipping, rollover, and immobilization after impact. The robot can roll freely in all directions, recover automatically after collisions, and maintain operational continuity even in uneven or unpredictable terrain.

The rolling motion significantly reduces friction and energy loss, enabling energy efficiency 5–6 times higher than legged robots, while also delivering exceptional speed and responsiveness.

High-Performance Motion and Endurance

The RT-G800 is designed for extended missions and rapid response scenarios:

• Instantaneous maximum speed of up to 35 km/h

• Cruising speed of approximately 18 km/h

• Acceleration to top speed in about 2.5 seconds

• Maximum climbing angle of 22 degrees

• Ability to overcome 300 mm vertical obstacles

• Continuous operation time of 8 hours or more on a single charge

• Maximum range exceeding 100 km per charge

Its terrain adaptability allows stable operation on hardened roads, grasslands, sandy surfaces, slopes, beaches, deserts, and uneven ground with surface fluctuations of 3–6 cm.

All-Weather and Extreme Environment Capability

The Rotunbot RT-G800 is built to operate where humans and traditional robots cannot:

• IP68 fully sealed spherical shell for dustproof and waterproof performance, including long-duration submersion

• Operational temperature range of –25°C to 65°C, with custom configurations supporting –45°C to 85°C

• Resistance to heavy rain, snowstorms, strong winds (up to grade 8), and hail impacts

• Ability to function in fog, haze, corrosive environments, radioactive zones, and flammable or explosive atmospheres for short durations

This makes the RT-G800 particularly suited for airports, oil fields, deserts, coastal zones, disaster areas, and industrial hazard zones.
