Automated rain shelters are usually fixed to one site. A three‐unit, portable, fully automated rain shelter system has been constructed for plant water stress research in Georgia. Each structure has a roof 8.6 by 7.2 m attached to four posts. Welded to the end of each post is an automotive wheel and tire assembly. Two smaller wheels (drive shaft driven by a geared‐down 746‐W 220 VAC motor) contact and drive the larger wheels. Two parallel irrigation pipe bumper rails guide the shelters. Movement onto and off of plots is controlled by one rain sensor and two limit switches. In studies with four sequential drought periods and a control, the total useful plot area is 0.05 ha.
