  1. Stability – It is the ability to remain unchanged over time under given conditions. For example, how well the AEV keeps its balance on a monorail track placed on the laboratory ceilings.
  2. Minimal Blockage – It shows how big the cross-sectional area of the AEV’s front is.
  3. Maintenance – The work of maintaining AEVs in proper condition; supports the AEV that keeps.
  4. Durability – Reflects how well the AEV withstands air resistance, steep slopes, or other external conditions.
  5. Safety – How well the AEV doesn’t introduce danger or risk. Also, it incorporates the placement of wires around the AEVs.

All the designs are close. We’ll want to do more testing, and refine our criteria/ make it stricter.
