Crawler Stair-Climbing Chassis

The tracked stair-climbing chassis is a robotic mobility base engineered for extreme environments. Replacing conventional wheels with wide-tracked crawlers, it achieves seamless navigation across complex terrains like stairs, mud, and snow through adaptive traction and a stable center of gravity. Its core strengths lie in triple reliability: industrial-grade protection against rain, snow, and mud; a worm gear reduction system ensuring slip-free stops on inclines; and 360° on-the-spot turning capability for agile maneuvering in confined rubble or stairwells.

Core application scenarios focus on high-risk environments: During firefighting and rescue operations, it carries thermal imaging cameras to navigate slippery staircases for fire scene reconnaissance; in wilderness exploration, it transports detection equipment into muddy farmlands or snow-covered mountainous regions; at emergency disaster relief sites, it ensures zero-failure passage for debris search-and-rescue robots.

Table Parameters

All-Terrain Capability

70cm wide tracks evenly distribute weight to prevent sinking in soft mud or deep snow. Special tread patterns automatically grip stair edges on slippery concrete stairs. The worm gear system instantly locks the tracks during power loss—even fully loaded on a 30° slope, it will never slip unexpectedly.

The compact 950×650mm tracked chassis, combined with 360° on-the-spot rotation capability, enables precise steering with a single command through narrow passages in collapsed buildings or staircase corners.

Industrial-Grade Protection

IP55 protection ensures the tracked stair-climbing chassis can operate continuously under fire sprinkler mist and shield internal circuits from rice paddy mud splashes. All interfaces feature laser-sealed construction, eliminating the need for additional protective covers in rainy, snowy, or high-humidity environments.

Research and Development Friendly Design

The dual-drive controller natively supports industrial protocols like CAN bus and RS-485, allowing direct integration of your thermal imagers, gas sensors, or robotic arms without rewriting underlying code. A standardized mounting platform is reserved on the chassis top, enabling quick 30-minute sensor bracket installation.

The worm gear reducer serves beyond mere transmission—it automatically locks the tracks during motor failure, preventing equipment from falling down stairs. Intelligent current monitoring instantly reduces speed upon encountering obstacles (like getting stuck in rock crevices), safeguarding both the motor and mounted equipment.

Precision Load

100kg represents the optimal balance point for staircase scenarios. Excessive weight causes uncontrollable shaking, while insufficient weight fails to support professional equipment. Field-tested verification: At this load, thermal imaging displays remain shake-free and gas sensor data exhibits zero drift, enabling equipment to deliver its full designed performance.

Cases Where Tracked Robot Chassis Are Not Suitable

1. Deep Water Zones

When water levels exceed the chassis's 20cm mark—whether in streets flooded by mountain torrents, pump rooms with accumulated water in chemical plants, or underground garages after heavy rains

2. Chemically corrosive zones

In spaces saturated with strong acids or alkalis—such as leaking sulfuric acid storage areas, electroplating workshop waste liquid ponds, or laboratory chemical spill sites

3. Steep staircases (>32°)

When stair inclines exceed the 32° critical angle—commonly found on steel ladders in aging factories, makeshift steps after landslides, or tilted loading platforms in warehouses
