Cleaning

Efficiency, quality end result and resource savings are essentially the advantages of using robots in performing different cleaning tasks.

In some cases, when these robots operate in harsh environments, it also involves providing security to this work.

Success cases – Robot for thermosolar plants cleaning

Valent is a robot–truck for solar thermal CPC plant cleaning. The equipment basically consists of a three-axle vehicle with total traction for 26 tonnes. Robotnik has made the control of the two robotic arms and the cleaning system. Its technicals features are:

  • Mirrors concentrate sun rays to heat the oil in the tube.
  • Oil goes to a heat interchanger and use the vapors of second circuit fluid to drive a turbine generator.
  • Dust loss reduces efficiency (usually up to 5% loss).
  • Semi-autonomous cleaning robot truck (tanker – 14 m3).
  • Highway-capable.
  • Increases reflectivity to 99.5%.
  • Parabolic brushes reduce water consumption.
  • 2 arms x 3DOF (adapt to distance, terrain).
  • Speed constant < 2km/h.
  •  HMI.
Success cases – Atomic Snail Robot

The snail robot has the mission to clean the vessel joint of a PWR type nuclear reactor.

The vessel closure is sealed by means of a set of silver o-rings, that when removed left some hazardous residues on the stainless steel surface. Those need to be removed safely prior to the new vessel closure, and this process was formerly done manually being the pool empty. The Atomic Snail Robot permits to perform this process autonomously being the pool filled, thus avoiding that the operators receive high doses of radiation and at the same time reducing the critical route, i.e. the time the nuclear reactor is not producing energy.

The robot has three mechanisms: traction, cleaning and filtering. It has been designed to be easy decontaminated and for its easy deployment and recovery from the vessel joint. The robot is controlled from the top of the pool by means of a simple control panel.
