+**THIS GITHUB REPO IS CURRENTLY BEING EDITED 05/13/26**
+
+## Motivation
+As drone delivery becomes increasingly common, there is a critical need to design lightweight but strong structural frames that can safely carry payloads without compromising stability or control. This project challenges students to apply concepts from Statics and Physics to optimize drone frame design using principles like force equilibrium, moments, trusses, and center of mass. The experience simulates real-world engineering
+decisions around tradeoffs between weight, strength, and performance.
+
+## Project Description
+This project challenges students to design a lightweight but strong drone payload structure by applying core statics principles such as equilibrium, moments, trusses, and center‑of‑mass analysis. Using MATLAB simulation, students will estimate payload capacity, analyze structural loads on drone arms, and validate stability for safe flight. Through iterative design, they explore real engineering tradeoffs between strength, weight, and performance in modern drone applications.
+
+### Suggested Steps
+Open the "DroneDesign_StudentProjectTemplate.mlx" Live Script in MATLAB as a starting point for your project.
+1. Gather your starter assumptions so you can plug in numbers later.
+    - Consider a quadcopter drone (4 motors) with a max takeoff weight of 2kg (including the payload)
+    - Each motor can provide up to 1kg thrust
+    - Arm length (you choose)
+    - Material (you choose e.g. aluminum or carbon, look up typical material properties)
+    - Acceleration due to gravity: $g = 9.81 m/s^2$
+2. Assume each arm of the drone is modeled as a beam or truss element. Using simplified geometry, propose 1-2 designs that will minimize weight but maximize payload capacity.
+3. Calculate the maximum payload capacity.
+    - First, calculate the net upward force available from motors
+    - Next, calculate the estimated frame weight from material and geometry
+    - Finally, calculate max payload capacity while maintaining equilibrium
+4. Use MATLAB to simulate force distribution and moments (*optional*: perform a finite element analysis by first creating your drone design in a CAD tool and importing the .stl file into MATLAB)
+    - Plot shear/moment diagrams for drone arms
+    - Calculate center of mass to ensure stable flight
+5. Create a simple animation or visualization showing drone geometry and payload lift
+
+### Expected Results for Project Solution
+1. Sketches of proposed designs
+2. Numerical value for maximum payload capacity estimated for each design
+3. Shear/moment diagrams for drone arms and center of mass for different force distributions and moments simulated
+4. Animation or visualization of drone geometry and payload lift
