This thesis describes the development of a system, used in moving a hot tub Jacuzzi. Described below is the integration into a house under construction, where required modifications were optimally executed. Movement capabilities extend from the bathroom to the end of a 15 m long terrace. From the bathroom, the hot tub exits via a motorized door and moves along the entire length of the terrace. The user can open the door and control the tub movement from outside or inside the tub. To control the drive electric motor, a frequency converter has been installed. A microcontroller with distance sensors monitors the distance to any obstacles, and stops the hot tub if an obstacle comes too close. The designed system can detect and monitor distances from 2 cm to 4 m and control the frequency converter. Repeatability has been achieved, which is of key importance. The fundamental purpose of the system is to ensure comfortable hot tub movement, and at the same time be simple to use by the user.
