Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
(3/17/15 | In Person) "Great job guys! Since you guys are looking into pallet jacks, I can acquire one for you to test out if you'd like."
Actions taken: Awaiting for acquisition of pallet jack from Frank to test out maneuverability. We are most likely going to stick with a static cart, but we can still obtain an idea of how a similar sized object navigates around the Village West.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
(4/1/15 | In Person) "Since you guys are considering a 4 bar linkage for your machine, try to define a specific path that you need to complete and I may have some information and software that will assist you in designing the linkage system you will need."
Response: After reevaluating the motion we are trying to accomplish, a 4 bar linkage system would be ideal if we needed a set motion consistently from operation to operation. However, taking structure settlement into considering, we can't be sure that the motion from our 4 bar linkage will be successful for every window we encounter. As a result, we steered toward a mechanically assisted motion with a gas spring that allows the user to have a better physical feel and get immediate feedback on whether or not the window can safely be removed.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
(Day of Risk Reduction Presentations) "One of my main concerns is the maneuverability of the machine."
Response: We have considered the dimensions of the areas that will be navigated and we are carefully designing our machine so that it can move around easily without any issues.
(Day of Risk Reduction Presentations) "Do you have to take the window out? Can you use some dual-sided cleaning tool?"
Response: Our concept design where it was not required to remove the window completely was a stretch concept. Our machine would definitely be less bulky, but because the angle we have to tilt the window is very small, trying to clean the window would be awkward and difficult. Taking the window out completely is more involved, but it's safer and seems like the most ideal method.
Risks and Areas of Concern
Cart maneuverability
Counterweight implementation
Steel vs. aluminum
Fastening vs. welding
Supporting the window after it's been removed to prevent it from just hanging in the air.
