Team Vision for Phase 1Our 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 DefinitionThe 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.
Use CasesThe ComQuaT system is a proof-of-concept device, the Use Case below includes an outline of future potential capabilities. The ComQuaT system will focus primarily on the Use Case below...
Project Goals and Key DeliverablesThe 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.

ConstraintsThe following constraints will affect our design options:
- Budget ($750)
- Operating Conditions
- Should be capable of operating at standard temperature and pressure
- Maneuvers on even ground
- Time of manufacturing will greatly affect our timeline
- Available lab hours will limit build time
- Available materials and resources will affect our design choices
- Must be operational by ImagineRIT (4/28/18)
- Air/Water tank capacity will affect pneumatic design
- Weight of air/water tank will need to be considered when deciding RC load capacity
- Electrical needs will dictate battery power required
- Battery life should ideally last 10 hours but must last one expedition made by the robot at a minimum
- Travel distance from RC base affects length of umbilical
- Deflated robot must be able to fit onto the RC base
- System should not injure nearby observers
- Meeting engineering standards (UL, RoHS, etc.)

Plans for next phaseBy our next review, our team aims to complete a system-level design of the ComQuaT system. This will include:
- functional decomposition of customer requirements
- finalization of engineering requirements and metrics
- brainstorm and comparative analysis of potential solutions
- exploring faculty and literature resources to assist in the design phase
- finalization of systems-level design choices
