Resumen:
Una universidad checa ha desarrollado un robot para limpiar fachadas y realizar tareas de inspección, como supervisar el estado de la fachada en aquellos puntos donde el vidrio se fija a la superficie, comprobando las alteraciones potenciales en la superficie de recipientes a presión hechos de acero resistente a la oxidación. El robot está equipado con sensores inteligentes capaces de identificar su posición en el espacio. Se buscan socios interesados en continuar con el desarrollo de la tecnología y establecer acuerdos de cooperación técnica, así como empresas para fabricar la tecnología bajo acuerdos de licencia.

Tittle:
Inspection and service motion robot for special applications on the vertically oriented walls
Summary:
A Czech university has developed a robot intended for façade washing and cleaning and for performing inspection tasks like supervision of the state of the façade at points where glass is fixed to the surface, checking for potential surface disruptions of pressure vessels made of rust resistant steel. Researchers are looking for partners interested in further development of technology based on a technical cooperation agreement and for companies interested in production under a license agreement.
Description:
Construction of high-rise buildings with façades made of protective flat glass fixed to supporting grids is a contemporary trend in modern architecture. There has been a long-term increase in the demand for devices and new technologies enabling users to deal effectively with problems concerning cleaning, inspection, installation and other service applications. Inspection of the potential surface disruptions of large pressure vessels is just one of many examples.

A number of service robots with different movement characteristics as well as various abilities to deal with surface height differences have been developed recently. The design of their holding system is the main difficulty. This system must be able to resist adverse operational conditions. There are two substantial problems: the effect of gravity caused by the vertical position of the device on the wall and the variable nature of the friction ratio of the surface which the device is operating on. Supporting elements mounted on glass façades, interspaces between individual glass façade parts and the state of the particular façade surface given by damp and varying degrees of dirt also have adverse effects. The system must also be endowed with sufficient load capacity for the technology or inspection superstructure.

That is why the Czech university has developed a robot intended for façade washing and cleaning and for performing inspection tasks like supervision of the state of the façade at points where glass is fixed to the surface, checking for potential surface disruptions of pressure vessels made of rust resistant steel.
The service robot consists of a compact duralumin frame connected to its rotary undercarriage by a rotating servo-drive. These elements constitute the body of the robot. The rotary undercarriage is mounted with articulated active suckers. It is possible to set the distribution of the suckers according to the character of the particular surface geometry, e.g. a façade system. The frame of the service robot is connected to four legs by means of versatile latches. The legs are also equipped with suckers and an individual electric rotatory servo-drive.

The robot is equipped with a number of intelligent sensors used to identify its current position in space. Drive control is conducted by an advanced control system based on a compact industrial computer platform to which input and output modules, a module for temperature measurement and a unit for wireless communication are added. The device falls into the category of semiautomatic systems with partial autonomy. It is intended to be used with other technologies such as low-weight cleaning devices for dry cleaning, cleaning with a minimum cleaning liquid consumption and applications for inspection devices.
