it's an ABB robot, likely an IRB 6400... 6 points of articulation...
certainly capable of greater precision work, especially with some sort of vision-guided robotics software. The software can easily be trained to recognize points of selection upon a given surface, and act accordingly, but unless they're willing to x-ray the pumpkin, I would imagine it will be much more difficult than that: Pumpkins vary greatly in terms of thickness..
funny story: I was at a tradeshow where ABB was demoing an IRB 7600 by attaching a 1000kg engine block to the end of the robot arm, and then whirling it around in all sorts of *very* high-speed patterns, showing off the strength and precision of arm..
The robot was pneumatically bolted to the floor, and the arms was capable of withstanding the pressure... Unfortunately, they miscalculated the torque that was getting generated, and the screws that attached the engine block to the flat steel panel on the end of the arm began to shear.
On the 3rd day of the show, an ABB engineer showed up, got a nice close look at wtf was happening, and freaked out, shutting the whole thing down... He estimated they were no more than an hour or two away from the engine block coming flying off, flying 40 or 50 feet, and killing a dozen or so people.
industrial engineering... good times.
