This is a challenge issued by friends and family. The goal here is to make a robot that can bring beverages from another area to wherever the people are , allow the person to get their drink , then leave. It does not need to be fully autonomous , even remote control is acceptable. It does not need to grab them from the fridge, preloaded beverages are acceptable. This is Ez Robot though, I believe we could do better than that! Well anyways to start the project off I am using a roomba base. I picked up a stainless steel trash can last night as a outside casing. I will show you the rest as we go

Moviemaker's Bobii Reborn From Frizby Bob
I decided to make a smaller test-bot. My wife said I could not buy or make any NEW robots. So, I took my BOB Frizby...

I also see you have a tailors tape. I was coincidentally given one about a week ago and find it very useful and easy to work with. I'm digging it.
Oh yea I realized that measuring things with curves tailor tape is s great idea.
Alright I pulled out the dremel and cut the compressor out , it was very easy. The hard part will be recovering the thermostat and that wiring. I need to grab a sharp chisel to get through the steel outer casing. I want to use as much original equipment as possible
As you can see the compressor is not very large. It's really the wiring and tubes that make it a tight fit but I have a plan that with give me about 4 inches more room all the way around. I will draw it but cannot make the case improvments until I get paid this weekend.
Look very hard to fit the compressor, the heat dissipator and the freeze element inside the little can you have, you also will have to reconnect all the tubing and bring new freon inside this unit, you take a very hard road jstarne1 !
I look forward to see your progress, I am interrested in seeing the batteries duration. Do not stop, go forward !
The compressor will only run while docked is the plan. The battery will power ezb , lights and Roomba.
Ok payday arrived and that means getting parts
Ok so I need to salvage parts from the refrigerator. One of these things is the temperature controller. Second is I needed to remove the evaporator and measure it so I know about how large to make the new one. Take in mind this one is being made from tubing.
I measured each length of this little maze of tubing in the evaporator. I measured approx 168 inches. Wow that's a lot of surface area! it more than I expected but with it woven together like this it's possible. Here my pic I measured on.
