We propose a novel haptic rendering scheme based on passive midpoint integrator (PMI), which is an extension of our prior non-iterative passive mechanical integrator (NPMI) to maximal coordinates for simulation of complex articulated rigid bodies and to multi-point intermittent contact with the linear complementarity problem (LCP) formulation incorporated. The proposed PMI-based haptic rendering then...
We propose a novel multi-rotor flying platform, ODAR (omni-directional aerial robot), which is fully-actuated (i.e., can assume arbitrary motion in SE(3) or generate arbitrary control wrench in se(3)) by six opportunistically distributed rotors, each driven by reversible ESC (electronic speed controller) for bi-directional thrust generation. Due to this omni-directional wrench generation, the ODAR...
We present a preliminary result on a minimum inertia scale factor that can be passively implemented into a human-robot interacting system. We model the robot including essential system components (e.g. force sensor dynamics and digital controller), and we analyze the energetics of this model using the frequency property of the human force. The resulting passivity condition is verified by simulations.
We introduce a new aerial manipulator system that consists of an airborne base actuated by multiple spherically-connected quadrotors and a manipulator rigidly connected to that base. We first model the dynamics of the system and show that attitude dynamics of each quadrotor is decoupled from the base-manipulator dynamics. Therefore, we can consider the quadrotors as thrusters to control the base-manipulator...
•We isolated the M1 strain from Manripo area in South Korea.•The M1 strain can increase the level of 2,3-butanediol in the genome.•We carried out whole-genome sequencing, then found 4 genes those are involved in the production of 2,3-butanediol.•The complete genome of M1 is composed of a circular chromosome of 5,865,090bp.
