I'm lost with the Create vs Create 2 vs Roomba part, as I have never used a create. |
…TURTLEBOT_BASE=create for Create 1 base, TURTLEBOT_BASE=roomba for Create 2.

Some more background in case it helps: I believe there was no "create 2" when this code was originally written, there was the Create 1 and a Roomba. The create 2 is a refurbished Roomba w/ the vacuum parts removed, which is why a Create 2 only works with TURTLEBOT_BASE=roomba. Someone who does not know the difference between a Create 1 or a Create 2 will put TURTLEBOT_BASE=create and their bot will not connect. This error message can help them see they should try "roomba" for Create 2. I will make a suggestion to update on the wiki tutorial also which will alleviate this problem too. |

improved error handling to alert user that sci connection issues can be caused by wrong baud rate or wrong robot base type. Users typically get a "check your cable" error and no other info. Often times the wrong robot type is causing a baudrate mismatch. For example, someone with a Create 2 using the "create" robot type will use 57600 baud rate when they should be using 115200 of the roomba.
