The WallRover A offers an alternative to scaffolding or cherry-pickers, without the limitations and cost of visual inspection methods, such as hand-held bore/ video/fiberscopes. The open architecture WallRover A gives the user unlimited freedom to customise and adapt the vehicle to their unique application, thanks to the embedded Raspberry Pi and Arduino control system. With a mission endurance of +15 minutes on vertical surfaces and +60 minutes on horizontal surfaces, difficult remote visual inspection tasks, such as crack width measurement, can be carried out whilst the operator is kept at a safe stand-off distance on the ground.
