Some generic advice is to adapt your recruiting techniques to the type of people that you want to recruit.

For example, instead of creating a poster to put around campus that says
"Like designing, building, and programming things? Come join the robotics team!"

try saying:

"Do you like writing, graphic design, public speaking or MONEY? Come join the robotics team!"

Although it is possible to find people that think robots are inherently cool and like business, in my experience those people are rare and you're better off finding members for your business team by recruiting directly to people that would originally join other clubs like Speech and Debate.
