    • Medical conditions
problem statement
Problem Statement
  • Our purpose is to build a ⅛ scale model of a chair lift for the AgrAbility project. The chair will lift paraplegic farmers into their tractors. It must conform to safety standards, durability standards, ease of use standards, and must stow away easily. It must fit within cost restraints. Furthermore, it must be able to operate without the tractor running.
