Beer Butler , Cans, Bottles Or On Tap With Built In Chiller

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 :)

Having a dome does give me open space to put sensors like the ceiling camera to read QR codes.

Ok so I did test some QR codes on the ceiling. The small QR code would read with a illuminator indoors at 2-2.5 ft reliably. The enlarged 400 x 400 line QR code was able to be read at 6-7 ft but it was only consistant every 2 seconds when at 5 ft distance. The largest QR code was approx 600 lines by 600 lines and read consistently in any direction at 7 ft 6 inches away with a 1 watt led illuminator. The next steps are testing if a IR illuminator will react the same and building it. I have 100 850 mm IR less for the next tests. Unless the camera control can determine angle of orientation on the QR code I will need to use a Compass module to determine orientation of the QR code landmarks.

So I needed to do small modifications to the case I bought for the JARVIS hardware while he is still being built and wired ect. The usb connectors and audio and Mic were all 2 inches to short to reach the plug and then they must navigate around or over the video card. I used a bundle of jumper wires to extend the cables about 6 inches in length. It was about 70 soldered connections but I got them extended and turned on the first time. The case is pretty for sure :). While I was soldering these connections my sister hijacked my phone to post on my Facebook " how pretty she was". Yup I really should put a lock on that thing. Lol

Hey at least the leds look awesome on this case. It. Would be better if the case was red though. Just saying :)

As for the QR code tests I now need to made a IR illuminator that highlights the ceiling to make the QR codes easy to read.

That is a really good looking case, Josh.

I tested the Camera reading QR codes from 7 ft 4 inches away and it does even better than with a bright white 1 watt led pointed at it. To make the camera read the IR light I had to remove the IR filter over the image sensor. This was very easy and increased the overall light sensitivity in low light like many homes are. Now I need to figure out how to read the angle that the QR code was read at so this can be formed into a simple landmark IR navigation system.
