In this episode we hear Kyle Gilpin talk about his work with
electropermanent magnets. Electropermanent magnets make excellent
connectors for modular robots as they are strong, small, solid state,
consume power only when connecting or disconnecting, and they can also
handle communication and power transfer. We also hear about how Kyle
used electropermanent magnets to build a 12 mm cube robot pebble. It
uses controlled disassembly to “sculpt” objects by releasing the
modules that aren’t in the object you want. We also talk about using
electropermanent magnets in motor applications. They are interesting
in this context, as they can operate at low RPM’s, which is important
when modules scale and it gets harder to use gear boxes.”

Electropermanent Magnets with Kyle Gilpin MIT in EP 3 of the flexible_elements Podcast
Kyle Gilpin is a PhD student in the Distributed Robotics Laboratory at
MIT. He holds BS and MEng degrees in Electrical Engineering and
Computer Science from MIT. Gilpin works to improve communication and
control in large distributed robotic systems. His past projects
include developing ultra-wide band radios, real-time image processing
systems, and reconfigurable sensor nodes. Before beginning his PhD,
Gilpin spent two years working as a senior electrical engineer at
Proteus Biomedical developing several ultra-low-power implantable
devices. Gilpin is the recipient of both NSF and NDSEG fellowships.

Hey Per,
After your comment on the electropermanent magnet article on Hizook, I was certainly looking forward to this podcast! I plan to listen carefully in the next few days, though it’ll have to wait until after my big demo (later today).
That being said, I should point out that the Hizook article provides abridged technical overview of the Electropermanent Magnets:

I can also recommend the post on Hizook, it is great,
I can recommend Hizook in general as there are many
great post already (check out the post on the Spiralift:
The Ultimate Telescoping Linear Actuator) there and
I am sure there are many more to come!
