Improved systems and methods for operating moveable architectural elements (e.g., furniture) are described. The system can include improved features implemented throughout various elements, including hardware elements, controller elements, and/or software elements. As one example, the system can feature the ability to map a characteristic load profile across a particular length of actuation and, if during operation a measured load exceeds the profile, adjust (e.g., stop) the system's motion. The system can also advantageously map its current draw to increase energy efficiency. In addition, the system can include a positioning system that enables it to automatically determine its position upon start up and during operation. In some implementations, the system includes multiple moveable elements (e.g., furniture items). In some cases, power is distributed to the moveable element(s) using a moveable power distribution module. Many other improvements and features are contemplated and described.

One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.
