Objective
Design and create a rough terrain structure that will comply with modularity and easy feasibility by fulfilling the customer requirement list.
Insights gained from last intake:
Partially fulfilling suspension performance
Load-bearing members require further stabilization
Customization options are limited for future generations
Inconsistency in design documentation
Requirements list
After analyzing the information from previous generation, it was decided to perform a corresponding study to get to know the target customers/users.
After performing a value stream mapping and interviewing, the requirements were developed by utilizing the Kano Model which helps identify basic, excitement, performance requirements
Design Methodology
Reference System
Development of any product requires a reference system to start from.
In other words, each system is developed based on an inspiration from external elements like nature, already existing products, previous versions of the same product, etc.
Carryover of characteristics is based on the technical requirements of the system itself.
Our reference system was based on a product which could give Pluto the ability to complete its target path (physical obstacles, grass, stairs) with ease.
Hence, a complete variation in the traction system was incorporated so that Pluto is ready to cover all possible future requirements

Prototype and Verification
Lessons Learned
Continuous cross-functional communication is essential to adapt to continuous sub-system changes.
Phase-wise planned verification and validation ensures reduced development time.
Developing a detailed system model during the initial phases is important for understanding sub-system interactions.
Suggested Improvements
Improvement of chain track performance by adding stable connector pins or adding additional dampening material to reduce vibrations in the traction system
More efficient space management for the electronic unit and battery compartment for better accommodation for all components including safely engineered routing of the wiring system.
Design of additional mountings for improved mounting of beer box.
