Fully automatic cleaning
This robot cleans aquariums fully automatically and removes algae and soiling from the inside of the glass walls. Initially the developers used metal bearings and brass bushings. However, the damp environment and contact with salt water and fish food sticks corroded the bearings relatively quickly and the brass bushings had to be lubricated constantly. This led to permanent failure and a great deal of maintenance work. Use of the lubricant-free drylin® guide rail with drylin® linear plain bearings from igus® solved the problem and made smooth and precise robot movement possible.
