Query: A programmable actuator for combined motion and connection and its
  application to modular robot   This paper proposes a new type of actuator at millimeter scale, which is
based on Simplified Electro-Permanent (SEP) magnets. The new actuator can
achieve connection and smooth motion by controlling the polarity of SEP
magnets. Analyses based on numerical simulation are used to design a prototype.
A dead-time controllable H-bridge and its multiplex design are proposed for
controlling the new actuator and simplifying the electronic circuit. Finally,
the new actuator is implemented in the DILI modular reconfigurable robot
system. The experimental results show that with this new actuator, the DILI
module can move smoothly and connect to other modules without power supply
during connection. The maximum speed of DILI module is 20mm/s.
