Team Vision for Phase 1

Our team aimed to adequately define the problem and assess preliminary requirements during this phase. This includes a Problem Definition, completed Customer Requirements, Engineering Requirements developed from the Customer Requirements, a clear understanding of the Product Use Case(s), and a list of the Key Goals and Deliverables for the project.

Our team was able to meet with our customer Dr. Lamkin-Kennard and refine our general-case scope as a “proof-of-concept” project with some potential applications for the far future. We were able to define and prioritize customer and engineering requirements that satisfied our customer’s expectations for the project and construct a preliminary plan for the rest of the design phase.

Problem Definition

The Soft Walking Robot is a partially to entirely inflatable device whose purpose is to test the future prospects of utilizing hydraulically or pneumatically powered limbs to create “walking” patterns in a robot. This project will produce a robot that can be navigated to a location via an RC vehicle, deploy, inflate itself in under 30s, and conduct a short expedition. This short expedition will consist of walking a distance of 10 ft while maintaining a straight path with less than 2 inches of deviation per 10 steps. The robot must operate for 10+ hours without tearing or incurring damage. The current model produced by Team 17227 cannot maintain balance while walking, and is not constructed with optimal materials and components. We will utilize the hardware and methods of previous projects to guide us, where applicable. The deliverables of the project will consist of a functioning prototype as well as appropriate design documentation.

Project Goals and Key Deliverables

The goal of this project is to design, develop, test, and fabricate a compressible walking robotic prototype. The system will be composed of an RC vehicle for transportation and a deployable robot that can inflate/deflate itself as well as complete an expedition of at least ten feet in a single linear direction. This device will contribute to proof-of-concept efforts that will result in more complex systems with potential applications for search-and-rescue missions.
