I have just finished building my robot, and am trying to upload the MakeBlock examples. When the program is about 90% uploaded, it returns this error:
avrdude: stk500_loadaddr(): (a) protocol error, expect=0x14, resp=0x55
I have tried multiple program examples, including the standard Arduino examples.
The port connected is okay (COM3) and I have the board set to Arduino Uno.
I know this has been discussed in other threads, in part because I have participated with some of my own experiences and speculations (with the Starter Tank Robot, but the avrdude message was similar). Have you tested the program to see if it loaded?
I don’t recall where some of the other discussion is, but I will see if I can find it.
I do recall that one possibility is that if you are using a current Arduino IDE, that >>might<< be an issue. Some people have said to use an old version (possibly 1.0.6).

Update 1:
Here are some links to other threads that >>might<< be helpful. The first one is the discussion I was involved with. The next two might be helpful >>if<< your Orion bootloader got trashed. Oh, There is another one where I described my experiences in a bit too much detail.

I hope these help.
Update 2 [2015-04-16]:
I found avrdude errors with BT and found a possible solution:
