Kinetic Hot Wire Robotic Arm Attachment




The idea of this hot wire cutter is to have the ability to reach behind the material to create super amorphic shapes. Unlike a router attachment that can only affect the surface, and has a difficult time reaching behind material. The advantage of a kinetic hot wire, is that you can expand and contract the wire, which will change the overall shape of the hotwire. The rigidity of a flat wire allows the contraction of the shape to return to its initial destination.

Hot Wire Attachment Test

Laser Cutting the gears for the hot wire attachment. We created a large gear in order to leverage more torque from the stepper motor that we had.

Project Developments

Each of the three teams is now working within the confines of three distinct types of robotic arm operations: weaving, stab-and-place (aka pick-and-place), and wire cutting.  In this case their design machines are custom tools/fixtures that fasten to the end of the arm, and work in conjunction with their operations.  Next week we’re moving into full production mode, during which time each team will work with the robotic arm at Radlab to fabricate their projects.  This past week the class met at the MIT Media Lab to go over their most current developments, and Peter Schmitt was generous enough to show the students around the lab, and give a presentation of his work.
