[edit] Micromanipulators

[edit] Prototype by Julien Lacheray

Gripping operation (1.5 MByte video)

Coils and magnets (856 kByte video)

In the absence of piezo-actuators (the order was delayed), an alternative actuation method was used for the prototype gripper. An extensive literature survey was done.
