Dimensions for end cap switch does not fit designed end cap.

Our design was dimensioned to manufacturer's

drawings. Drawings from manufacturer's website

were incorrect

Find and buy a new switch that will fit the dimensions in the end cap. Or manufacture a

new end cap that contains more space for

larger switch

A new switch will be bought that fits the dimensions that we

require and therefore will not require any

additional manufacturing

A new switch was used and the end cap was

very slightly modified to fit the new switch.

The switch fits in the end cap and there were no issues fitting it with the

cane.

Threading wires through cane is more difficult

than planned and interferes with roller sub

system

Wire was changed from enameled wire to

insulated wire, to reduce short circuits, insulated

wire is thicker than enameled

Use a mixture of enameled and insulated

wire, Work with insulated wire by

bending it and possibly cutting out some

material

More slots will be milled in the bottom of the

cane handle to fit the insulated wire.

More slots were milled out in the bottom plate

of the cane and insulated wire was used.

The cane handle is fully assembled and all parts fit

together, rollers are not hitting the wires.

+Imagine RIT

We are on track with deliverables for Imagine RIT.

+Lessons Learned Problems Encountered

Many Should have enlisted help from SMEs and other electrical engineers

Learnings Practicing presentation with guides helps Risk assessment is only useful if we use it to an end 2 guides are better than 1 Plan ahead and stay ahead to cushion risk Stick to project plan, do not push deadlines out

We learned from many encountered problems

+Recommendations

For Future Work: Ability to detect changes in elevation Ability to provide feedback on proximity to obstacles Designing a system that requires smaller batteries Making battery removable more user friendly Signal to user to let them know that battery is low while in use Add a vibration to stop feedback One D-shaped shaft for system Fewer small parts and a more “streamlined design” Simpler assembly
