Recent accomplishments
Lauralton Hall's engineering team consisting of 43 students in grades 9-12 recently participated in its sixth Sikorsky STEM Challenge and won. This year, students were asked to design a lightweight, semi-autonomous cargo transport system with color recognition abilities that would assimilate into the Sikorsky Skyhawk model. The system when activated will drive the Skyhawk rig to the identified colored building top, engage the hoist motor to retrieve the payload with the magnetic hook, and then return the Skyhawk rig to the starting location. The Lauralton Hall design utilized ergonomic buttons for activation and a 3-pulley system to reduce the strain on the hoist motor. Using an Arduino Uno, they programmed a color sensor to detect the correct rooftops and programmed the movements of the hoist and Skyhawk motors. Much of the mechanical design was created on CAD software and 3D printed at Lauralton Hall; this provided the foundational anchoring of the sensor, hardware, and electrical components of the system.

The Lauralton Hall Golf team won the 2023 SCC Girls Golf Championship at Blackhawk Country Club on Thursday, June 1 with a score of 388. Isabella Thomas '23 was also named to the SCC All-Conference team for girls' golf.
