Iteration 1: Data Collection to Validate Assumptions

Prototype 1 Goals

Prototype 1 Plan

Collect data from driving the rover climbing out of different positions & while turning
1. This should be data that we can derive torque from – i.e. speed and/or current draw – so that we have a comparison of our theoretical torque calculations versus actual
Compare the different tread styles while field testing, looking at each style's climbing VS turning abilities
1. Qualitative comparison, but also compare the torque data (which ones were visually successful at the different trials, while also requiring the least amount of torque?)
2. How well do the treads hold to the wheel? How long can we drive before they start to wear and worsen in performance?
Document any high-stress points in the drivetrain and chassis system that required repair at the end or throughout the tests
1. Based on this initial testing, we'll update the design based on the areas we believe don't have enough reinforcement
2. What is the effectiveness of the differential bar, in its current position and with its current design?
Test the rover driving over real terrain and obstacles
1. Document any initial, sticky points in the design that can be modified in Prototype 2
2. Determine the rover's centre of gravity. Can also do this by placing it on a platform and tilting it to different angles up to 45 deg

Task List for Prototype 1

Iteration 2: Flesh Out a Near Finished Project (i.e. Initial Build of Design)

Prototype 2 Goals:

Prototype 2 Plan:

Perform FEA on the structure before manufacturing
1. Document any high-stress points in the drivetrain and chassis system that required repair at the end or throughout the tests
2. How robust are our components?
3. How much does the chassis rock during traversal? Are the electronics enduring any shock?
Determine qualitatively through field testing
1. How much does our climbing ability require on driver precision?

Iteration 3: Final Touch Ups / Optimization

Integrate higher quality production materials such as carbon fiber for structural members
Consider FEA for mass optimization
Reduce unique parts and BOM
