Samenvatting
Modern actuation schematics become increasingly
ingenious by deploying springs and locking mechanisms in
series and/or parallel. Many of these solutions are, however,
tailored for a specific application and a general schematic that
allows for drastic energy reduction remains a challenge. We
have developed a series-parallel elastic actuator (SPEA) based
on a symbiosis of multiple motors, springs and locking mechanisms
in parallel, which we call +SPEA. This paper introduces
the novel +SPEA concept. We present a first prototype, a
+SPEA model and a control strategy that optimizes the energy
consumption, and experiments to verify the working principle
and recruitment strategy. The experiments show a good fit
with the model and currently the actuator reduces the required
energy in blocked output experiments by more than a factor 4.
