A supervisory control system for a multi- ?fingered<br />

robotic hand using ?datagloves and a haptic device<br />

Youtaro Yoshimura and Ryuta Ozawa<br />

Department of Robotics, Ritsumeikan University, JAPAN<br />

• This paper proposes a supervisory control<br />

system for a multi-fingered robotic hand<br />

for grasping an object in a remote<br />

environment in several ways, manipulating<br />

it, and mimicking several non-grasping<br />

motions.<br />

• The proposed control system consists of a<br />

grasping selector in the master system<br />

and motion controllers and a controller<br />

selector in the slave system.<br />

• The grasping selector learns to detect<br />

motions using datagloves.<br />

• The controller selector determines the<br />

current command and awaits a transition,<br />

while the motion controllers stably realize<br />

the currently commanded motion.<br />

Whole-body Force Sensation by Force Sensor<br />

with End-effector of Arbitrary Shape<br />

Naoyuki Kurita, Toshiaki Tsuji<br />

Saitama University, Japan<br />

• The contact location can be calculated by<br />

a force sensor<br />

• A method for estimating the contact point<br />

on an end-effector of arbitrary shape is<br />

proposed<br />

• The method utilizes the property that the<br />

external force direction changes when the<br />

end-effector has contact<br />

• Experimental results show availability for<br />

a non-convex shaped end-effector<br />

Autonomous Construction of a Roofed<br />

Structure: Synthesizing Planning and Stigmergy<br />

on a Mobile Robot<br />

• A mobile robot, according to a plan, builds a structure that it can enter.<br />

• The robot interacts with the construction using local sensing.<br />

• This synthesis of planning and stigmergy opens the way to new<br />

construction techniques using mobile robots.<br />

Experiments in Quasi-Static Manipulation<br />

of a Planar Elastic Rod<br />

• Equilibrium configurations of a planar<br />

elastic rod are solutions to a geometric<br />

optimal control problem.<br />

• We prove that the set of all solutions to<br />

this problem is a smooth 3-manifold that<br />

can be parameterized by a single chart.<br />

• This result leads to an algorithm for quasistatic<br />

manipulation planning that works<br />

well and is easy to implement.<br />

• Hardware experiments validate our<br />

approach when the “rod” is a thin, flexible<br />

strip of metal that has a fixed base and<br />

that is held at the other end by a robot.<br />

• We aim to enable people with motor impairments to interact with the world<br />

through mobile manipulators<br />

• The video shows our collaborator and pilot tester, Henry Evans, who is<br />

quadriplegic, using a PR2 to interact physically and socially<br />

• The user interfaces developed allowed<br />

Henry to shave, retrieve objects, open<br />

drawers, and give out candy at<br />

Halloween<br />

• These results illustrate the potential of<br />

robots to increase the independence of<br />

people with motor impairments<br />

• Manipulating function is added<br />

to the end effector with<br />

omnidirectional driving gear.<br />

• This manipulating function can<br />

be useful especially for limited<br />

narrow space.<br />

• The input gear mechanisms<br />

with passive rollers for<br />

smooth power transmission<br />

were examined.<br />
