The Truth Behind the 82% Failure Rate of Robot Chassis in Coastal Projects

Why do chassis in coastal projects always fail within 2-3 years?

In coastal engineering projects, corrosion and rust on robot bodies and components are very common issues. The failure rate of chassis components in salt fog environments is significantly higher than the average for inland projects; particularly in marine environments, their service life and operational performance fall far short of expectations.

Coastal areas are characterized by high humidity and high salt fog concentrations, and salt fog is inherently corrosive. When these microscopic particles adhere to metal surfaces, they cause pitting and crevice corrosion. As the chassis serves as a critical component for supporting and connecting equipment, any rust-induced perforation can lead to system failure, with repair or replacement costs often exceeding the original value of the equipment.

In response to these unique environmental conditions, corrosion-resistant design is key to adapting robots for coastal use:

In terms of material selection, the equipment prioritizes materials with superior salt fog resistance over ordinary metals. This enhances corrosion resistance at the material level and reduces the erosion of the chassis and components by salt fog.

For critical structural components, reinforced sealing is applied to transmission structures and joint seams to minimize the likelihood of salt fog and moisture penetrating the equipment’s interior, thereby preventing core mechanical parts from rusting due to moisture exposure.

Electrical components and circuit interfaces also employ sealed designs, combined with corrosion-resistant insulating sleeves, to slow down circuit aging caused by salt fog and reduce the likelihood of electrical failures.

Additionally, to address high failure rates, our company mandates that environmental classification testing be conducted on metal materials for projects in coastal regions.
