Definitely seems feasible. There are a couple of motor control capes that could help you out like this one<http://beagleboardtoys.info/index.php?title=BeagleBone_Motor_w/_Screw_Blocks>. There's no real support or substantial documentation for them, but presumably someone has used them before and you can get going quickly.
There are some resources<http://www.ti.com/lsds/ti/apps/motor/end_equipment.page>on the TI site that may help you guide your decision. You may also find success with boards more purpose-built for robotics like the Robovero<https://store.gumstix.com/index.php/products/262/>, or even Arduino-based<http://www.mouser.com/ProductDetail/Arduino/A000079/?qs=gMoqXxk%2F%2F5arlTJCT4KaEg%3D%3D&gclid=CNi-ppXZ77kCFet7Qgod_2UATw>platforms (although it'll make developing the app interface a little more challenging). Good luck!
