if robotic locomotion is ever to achieve some of what we want, it will have to use less energy.
a biped robot design being built by researchers at oregon state university holds the potential
to reduce energy use while improving robotic locomotion. this work reflects some important
fundamental advances in the understanding of robotic motion. humans deal with this problem
by flexing opposing pairs of muscles, to change the dynamic properties of their arm.
for a robot, the more it is able to do one of these tasks, the less able it is to do the other.
animals, including ostriches, have a great ability to respond to unexpected disturbances
while running, and can provide insights into the needed robotic equivalent – combining
spring-mass models with 'force control actuators'.

in the spring. different springs of widely varying stiffness can quickly be exchanged.

for robotic manipulation tasks in uncertain environments, good force control can
provide significant benefits. the design of force-controlled actuators typically revolves
around developing the best possible software control strategy. the newest findings from
the dynamic robotics laboratory at OSU are being presented at two conferences, including
the IEEE conference on robotics and automation. more info is available here.
