For the most part what scares people away from programming (at least in my experience) is the notion that programming is "hard". Staring at long lines of text or giant convoluted labview diagrams is intimidating to someone who's never done compsci before. The myth of programming somehow being some mythical impossible to do task needs to be dispelled first.

Also make sure it is clear that no prior experience with coding whatsoever is required to learn how to program, the skills of programming can be learnt somewhat painlessly if a person has enough motivation and dedication.

I noticed this year that you guys were using C to program your robot. (I could be mistaken) If your volunteers happen to show up late in the year or they don't feel they can learn text based code then Labview is always a good alternative. In the 2010 season I taught myself how to program in Labview during the build season without any prior experience with compsci in general. Labview in general is rather intuitive and learning it was not too challenging. Good luck with your search!
