Available only to High School Students (Grades 9–12)

This hands-on engineering project challenges students to improve the functionality and comfort of a real-world dog wheelchair used daily by a mobility-impaired dog named Zeca.
 

Students will explore two design pathways:

1. Rest-Assist Mechanism
Dogs in wheelchairs are typically locked in a standing position and cannot sit or rest while strapped in. Students will design a safe modification or add-on that allows a dog to transition into a seated/resting position without being unbuckled. Concepts may include pivoting rear supports, hinge mechanisms, stability systems, or assisted return-to-stand designs.

​

This pathway integrates:

• Mechanical design (Fusion 360 CAD)

• Prototyping and 3D printing

• Safety and stability engineering

• Real-world testing and iterative refinement

​​

The following modification will only be attempted if the rest mechanism is completed and time permits this summer.

​

2. Uphill Power-Assist System 
Dogs often struggle on inclines and ramps, requiring owners to bend down and push—placing strain on both dog and human. Students will design a lightweight assist system, such as a small motorized add-on with adjustable remote control, to help the dog climb gentle slopes safely and independently.

This pathway integrates:

• Mechanical design (Fusion 360 CAD)

• Prototyping and 3D printing

• Arduino / microcontroller integration

• Motor control systems

• Safety and stability engineering

• Real-world testing and iterative refinement
