More About Our Products
A mobile robot chassis is the fundamental movement platform that carries sensors, controllers and upper functional modules to realize unmanned locomotion. It consists of drive motors, wheels or tracks, frame structure, power supply, navigation controller and expansion interfaces. Wheeled chassis move fast and consume less energy on flat ground, while tracked chassis deliver better grip and obstacle-crossing ability on rough, muddy or sloped terrain. Explosion-proof chassis are specially certified for operation in flammable gas environments. A reliable mobile chassis determines load capacity, moving speed, terrain adaptability and navigation stability of the whole robot. Goldilocks provides nine standardized wheeled and tracked chassis models for agricultural, industrial, hazardous-zone and outdoor unmanned system development.
When selecting a mobile robot chassis, buyers should focus on several core parameters. Load capacity determines how much upper equipment the platform can carry. Moving speed and climbing angle reflect working efficiency and terrain adaptability. Drive mode, whether wheeled or tracked, should match site ground conditions. Navigation support, including autonomous navigation and remote control, affects unmanned operation capability. Expansion interface quantity and type decide sensor and module integration flexibility. For hazardous zones, explosion-proof certification is mandatory. Battery life and protection grade influence continuous outdoor operation. Goldilocks nine chassis models cover different load, speed, terrain and safety grades, helping customers match proper platform for inspection, patrol, transport and agricultural robot projects.
