[Chris] made his own extruder out of a hot glue gun and … Read the rest
The problem of gripping all surfaces has always plagued the field of climbing robotics. But if you don’t care about damaging the wall, why not just let the robot glue its feet to the surface. That’s exactly how this robot does it, using a couple of climbing feet in conjunction with a hot melt glue gun wielding arm. It … Read the rest
The T-1000 was the shape-shifting robot from T2 (the second Terminator movie). It was so amazing because it could assume the form and texture of anything; humans, piercing weapons, inanimate objects. This robot doesn’t even compare, except for one small trait. When it needs a tool, it can build it as its own appendage. This really is nothing more … Read the rest
