Bound to help: cooperative manipulation of objects via compliant, unactuated tails

Young-Ho Kim, Dylan A. Shell

Kinematic modeling of wheeled mobile robots

Patrick F. Muir, Charles P. Neuman
1987 Journal of Robotic Systems  
When the end-effecter comes in contact with an object (e.g., when picking-up an object and placing a peg in a hole), the structure becomes a closed-link chain and actuator conflict m a y occur.  ...  WMRs contain multiple closed-link chains [53] ; whereas stationary manipulators form closedlink chains only when in contact with stationary objects. .2.)  ...  In contrast to manipulator dynamics, we must resolve the special problems of closed-link chains and higher-pair joints.  ...

Folding in and out: passive morphing in flapping wings

Amanda K Stowers, David Lentink
2015 Bioinspiration & Biomimetics  
The mechanism consists of an unactuated hand wing connected to the arm wing with a wrist joint. Flapping motion generates centrifugal accelerations in the hand wing, forcing it to unfold passively.  ...  Using a robotic model in hover, we made kinematic measurements of unfolding kinematics as functions of the non-dimensional wingspan fold ratio (2-2.5) and flapping frequency (5-17 Hz) using stereo high-speed  ...  For instance, the Nano-Hummingbird (Keennon et al 2012) is a 19 gram flapping winged vehicle which attains controlled flight without a tail, using only the wings for control surfaces.  ...
