SMARS Firefighter MOD mod

thingiverse

I remixed the SMARS firefighting robot as I printed and assembled it. Most of these changes are because items were too loose or didn't quite work after I printed them. The 2 biggest changes are the top and the chassis. I purchased these rechargeable 9v batteries from Amazon and had to have a hole for the charger to fit in. Now I don't have to dissemble to charge it. https://www.amazon.com/gp/product/B07F67HC2C/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 I changed the top using tinkercad to put my department's initials on it and to place put crossed axes on it. I could not figure out how to design a Halligan, so no irons. EDIT: 8/7/19 8/7/19 Since making this firetruck I have made some changes. 1) I could not get the TicTac container to be water tighter under pressure. It would leak every time the pump ran and not spray water. So I changed to a pill bottle. This has a locking top and will hold pressure. 2) The next issue was refilling. I ended up buying some push to connect fittings so I can easily remove the top of the bottle and refill. 3) I don’t like pressurizing the water container to spray water, so I bought this pump (https://www.aliexpress.com/item/32826240881.html?spm=a2g0s.9042311.0.0.1bca4c4dh8Jw0C). It works a lot better and I don’t have worry about water tight. I am doing a redesign from the bottom up and will incorporate this new pump into it. 4) Last note is the balance is off. The pump hanging off the back and the water not centered make it back heavy. When it first starts it has a tendency to tip back. 5) I still need to fix tracks/wheels but I think I will try to do that in my next one. My redesign I am planning on will hopefully address these issues along with a few other ideas I have. This Thing will not be modified.
