Today more cad decided on the design also Your responseEnd UserScientists. Explorers, students hobbyist Need/problem/opportunityPeople physically interact with dangerous or inaccessible environments [exp. Toxic substances, Extreme temperatures and or unstable structures and compressors] there direct hand contact Poses a risk of injury.Research existing project designs. Annotate your drawings/pictures with the design factors: Function (what it has to do), User needs & requirements, Materials & components used, operating environment, safety, cost, waste & energy Interesting or key features, Drawings/Pictures- this is a rotating linkage mechanism intended to translate a small amount of input energy into a larger reaching motion .Function: Reference design showing a fully articulated robotic hand with multiple finger segments, used to understand feasible complexity for a manual/mechanical (non-electric) version.User needs & requirements: Demonstrates the level of dexterity possible, but also shows that fully articulated designs like this are complex — informs a decision to simplify for a low-cost, non-electric version.Materials & components: Multi-part assembly with distinct segments per finger — useful reference for component count and joint placement.Operating environment: Original design appears intended for controlled/lab conditions; my version needs to withstand harsher conditions (moisture, chemicals).Safety: N/A — reference design only.Key feature/limitation: High dexterity, but likely too complex and costly to replicate within a $10–20, non-electric constraint — informs the decision to simplify the final design.Source: [add the link/citation where you found this] Drawings/PicturesFunction: Early concept mapping of where joints and tendons would need to be replicated mechanically to achieve hand-like movement.User needs & requirements: Highlights that the design needs multiple independent points of articulation (fingers) rather than a single rigid claw, to mimic natural grip.Function: Illustrates the core hazard this project addresses — direct skin contact with an unknown or hazardous liquid.User needs & requirements: Reinforces the need for a barrier device that lets the user interact with liquids/substances without direct skin exposure.Materials & components: N/A — hazard reference photo.Operating environment: Confirms the device must be tested for submersion resistance (already reflected in your evaluation criteria).Safety: Central justification for the whole project — this is the exact scenario the mechanical hand is designed to prevent.Key feature: Visual evidence supporting the problem statement in Section 1. Evaluation of existing products(brainstorm results)Thoughts and ideas for my project:Mechanical hand that extends off your own hand and uses ledges and transfers the force from your own hand to the mechanical hand that even under high risk jobs is ok as it is only 3d print and you dont actually hurt your own hand Glove and tension cable design Telescoping rod and claw designHydraulic
