Exempel på hopping

• This strategy regulated the hopper at different hopping heights and was efficient even when hopping over obstacles.

• The genetic operators initially tuned the control input at every hopping interval, ensuring minimization of the error between the desired and actual height.

• Purely passive systems cannot sustain hopping motion on level ground indefinitely due to energy losses.

• The paper presents a solution to cycle hopping and a new transmit coding based on pulse duration to differentiate neighbouring transmitters in the ring.

• The tendency toward in-phase hopping on the virtual treadmill may be related in part to inertial loading of the metatarsus during swing by the robot.

• Experimentally, they demonstrated periodic hopping motion when the valve was activated periodically with a square wave function.

• Supralocalization, that is, spreading of a local linguistic item to larger areas, dialect hopping, and dialect contact involving accommodation are at issue here.

• Singlelegged systems have simpler configurations and admit only one gait, namely, hopping.

• Broadly, two types of legs have been used in single-legged hopping robots, namely, telescopic leg and articulated leg.

• Generally, one-legged hopping robots had nonlinear continuous-time dynamics with nonholonomic constraints.

• They controlled hopping height with an open-loop controller.

• Their first planar prototype demonstrated some limited hopping abilities.

• We have attempted to cover development of prototype models as well as theoretical models of such hopping systems.

• Thus, this leg spring arrangement played an important role in the hopping motion.

• This paper is a review of different aspects of research work on hopping motion of single-legged robots.
