Electroadhesive Surface-Climbing Robots

electroadhesive surface-climbing robot on wall

SRI offers licenseable surface- and wall-climbing robot prototypes for surveillance, inspection, and sensor placement applications. Ideal for remote surveillance or inspection of concrete pillars or other structures (such as bridges and tunnels), the robots use SRI’s patented electroadhesion technology to enable wall climbing. They can also be used to carry payloads such as cameras, wireless network nodes, and other sensors.

The robots extend capabilities of human operators and devices in potentially inhospitable outdoor environments, allowing potentially sensitive inspection or surveillance to be carried out at minimal risk and expense.

The technology and design of SRI’s robots may be adapted to fit the needs of specific applications. Contact SRI to discuss its potential for your project.

Electroadhesive robots enable

  • Sensor placement above ground clutter
  • High-resolution inspection of vertical surfaces
  • Automated mapping of 3D structures
  • Automatic detection of cracks 


With its wall-scaling robot prototypes, SRI has demonstrated robust clamping on materials that include glass, wood, metal and concrete.
