RAMPS and arduino mega have lowered costs much thanks to RepRap movement. How much it would be useful to use it to drive a robot?
4 drivers could drive the base wheels and the last an ultrasonic sensor. Endstop headers could be used to drive servos? Heated bed and extruder heater could drive instead high power peripherics like a big lamp or pump... Or just keep doing what it does well and leave behind 3d printed objects!
If you head that route,
I would leave the endstop headers for switches of some nature (bump, optical, magnetic) There are enough open headers to drive servos from.
Just add legs to your 3d

GeoWalker is one of my favorite robots!
If it had a lower print point i believe it could print nice things.
But the Geowalker uses servos to move. What i’d want to do is to use the ultra popular stepper driver to drive wheels.
