1) The document discusses the design of a gear system to pull weight as fast as possible given limitations of resources, manufacturing processes, and a tight timeline. 2) The proposed design centers around maximizing efficiency of a small torque motor using a planetary gear train system limited to 3 gears. 3) Next steps include calculating tooth strength, producing technical drawings, testing the design, and redesigning if needed.

3. Idea for the actual design
• Based around maximum motor efficiency
• Gear trains
• Limited to 3 gear trains, every extra train added 21mm
width and decreased efficiency
• Diameter of pinions : 16mm
• Diameter of gear : 69mm
• Final shaft of 6mm
• Module : 1
• Large gears diameter based on calculated gear ratios
• Estimated 28s for 1m
