Problem we solve

The robotic barn is the home of the cows and the workplace of the dairy farmer. It is a tool for milk production and the milk business. The dairy farmer builds a robotic barn on average once every 15 years and as an investment it is the largest, which the dairy farmer invests in during his career - averaging about 2x the annual turnover. Therefore, it has a high expectation value for the investment. 

With the acquisition of a milking robot, significant labour savings are hoped for, as well as better animal welfare for years to come. The barn should also be able to meet environmental and consumer requirements during its lifetime. A barn built today 2021 must meet these requirements up to 2035-2040. 

These expectations were not met for most investments. The reason is the inability of the milk producer to update and introduce new work routines.  

The technical constraints of the barn can be an obstacle to the introduction of the most modern and cow-friendly care methods. Also, there is ignorance about the environmental impact of barn use now and in the future.

” We help progressive dairy farmers to improve their skills and facilities so that they will have a justification to produce milk in socially acceptable, economically and environmentally sustainable ways to ensure animal and human well-being.”

4dBarn® Invest - Farmstead plan is the first design step

4dBarn® Boosted – Improve your existing barn production and labour efficiency

4dBarn® Designed – A robot barn designing, training and the layout

4dBarn® Ventilated – Calf barn ventilation and Dairy barn cooling

  • Questions in Your mind? What kind of different investment paths could our farm have? Can I use my existing facilities as a part of switching to AMS?

    Am I able to get a well functioning barn with a lower investment cost? Where should I put my new barn and secure future expansion? Can I fix existing barns to a new use? What is the ball park cost of these different options?

  • From the beginning of the planning process, 4dBarn® works actively with farmers; pointing out main and side tasks in the barn and combining those together for greater efficiency.

    The result is a functional stall, gating, and traffic flow plan with a routine working procedure.

  • 4dBarn® Ltd analysis is based on an improved international database. 4dBarn® Boosted – Improve robot barn processes and work efficiency

  • Ventilation service helps to design and improve new or old calf barn ventilation. Raising calves is always challenging, but it does not have to be.


  • The design process was smooth and the result is really good. The individual needs of the farm are taken into account in 4dBarn®’s activities. Our new barn surely pays itself back via saved time and increased wellbeing of the animals. I have also recommended 4dBarn® to my acquaintances. 4dBarn® Designed 1 robot
