No, but you would have to dismount the board from the robot every time you revise its firmware.
To get a feel of what Pogo contacts are like, think of a child's pogo-stick -- a spring-loaded rod (but w/o foot-rests and handle-bar), all metal parts and shrunk down to a couple mm diameter and 10 long. One end is fitted with a shaped contact point, and a wire (or PCB-track) would connect to the other. Four to six of these would be held in an insulated block while some means for pushing the assembly against the BDM pads on the board would exist. Obviously, means for countering that force would be required. These Pogo-contacts are production-tools
, and are not something you would ordinarily employ. Visit this site to see details, and the variety of, Pogo contacts:http://www.mill-max.com/products/newpro ... cfm?pid=14
However, this is the ONLY way to achieve your goal of not soldering to the robot's PCB. (Well, not exactly "ONLY", because I can see bolting
of tiny wire-lugs to the BDM-pads through their 1 mm dia. via-holes, but that
becomes a job for a watch-maker, which I presume is not w/in your skills scope.)
