Technology on designing a gondola-typed robot (WallBot) with autonomous driving function on wall for vertical outer wall maintenance (painting or outer wall cleaning)

 

Client / Market

  • Large plant and high-rise building construction company
  • Cleaning service provider for glass outer wall of high-rise building
  • Cleaning fluid and paint manufacturer

 

Necessity of this Technology

  • Outer wall maintenance for a high-rise building was done by a worker on a rope or a gondola installed at the rooftop, and this resulted in high industrial accident rate.
  • This leads to an increase in maintenance labor cost resulting from lack of new manpower due to poor work environment with a risk of death and aging of existing technicians, declined service quality, delay in construction period, and increased construction cost.
  • Due to the pressure of potential safety accident of laborer, the labor cost increases and the productivity decreases.
  • The risk of accident is decreased as the laborer works in a safe place.
  • The construction cost is reduced while the productivity and construction quality are improved.
  • With an increasing number of high-rise buildings and buildings with curtain wall or glass finishing, the demand for cleaning also increased.

 

Technical Differentiation

  • Possible to realize automation of maintenance work of high-rise building outer wall
  • Possible to automatize large area cleaning and painting work
  • Easy horizontal shift using a hanger apparatus

 

Excellence of Technology

  • The gondola robot’s performance and feasibility analysis result showed practical outcomes such as break-even point of 1.6 years and annual construction cost reduction effect of 16.9%.
  • Demonstration at new apartment construction site was conducted twice (Wonju, Jincheon)
  • Participated in 2014 International Construction Equipment Exhibition and Creative Korea 2014
  • 19 promotional materials published in YTN, etc.
  • Received the Ministry of Industry Citation for Man of Merit for Robot Industry
