Not quite accurate. Depending on what you're doing ruby2c might work.  
Given that it is a robotics program, we're generally talking fairly  
boring prorgamming anyhow. It might be translatable with ruby2c,  
possibly even without much work.

Presumably so he can download the program to the robot and ruby  
doesn't run there.

There are several much easier ways to make your ruby fast. Usually  
keeping most everything ruby. Full ports are my absolute LAST option.
