Motor torque requirements
○ 2x 40W motors
Rack material requirements
○ Cantilever beam model: 𝝉 = 390 kPa ○ 𝝉y = 215 MPa (stainless steel)
Optimal positioning for mounting/dismounting
○ User observations showed ~45º at the top
45º 350 lbs
Curved rack and pinion design works!
○ But requires strong (and expensive) motors
Constraints are important
○ Compliant materials do not maintain proper alignment ○ Need to increase points of contact to guide racks
Add protective housing to rack/pinion for safety and cleanliness
○ Exposed teeth could cause pinching or jamming
Next Steps
