The goal of this thesis project was to develop a prototype active ankle-foot orthotic design tool using novel generative algorithms in Processing 3. The project focused on the following research question: Can a custom active ankle-foot orthotic be created that is lightweight and supports the strength requirement using new techniques, such as generative design and custom 3D printing algorithms, and still meet the specified criteria, such as durability and comfort, for patients with Spastic Cerebral Palsy? The vertical support, composed of support legs and the calf support, was analyzed using finite element analysis and redesigned using a generative algorithm. The vertical support was then manufactured with custom G-code for 3D printing. A design for the direct drive actuator system was analyzed to determine the required motor torque. The actuator system will measure the resistance from the patient's foot and either increase the applied torque when the resistance is below the setpoint or reduce the applied torque when the resistance exceeds the setpoint. A prototype of the active ankle-foot orthotic design tool was created, along with a sample print of the vertical support, as a proof of concept, but future work is required to finalize the tool
