Using Bayesian optimization to guide probing of a flexible environment for simultaneous registration and stiffness mapping

Elif Ayvali, Rangaprasad Arun Srivatsan, Long Wang, Rajarshi Roy, Nabil Simaan, Howie Choset
2016 2016 IEEE International Conference on Robotics and Automation (ICRA)  
In this work, we use both stereo and contact measurements in a complementary manner to obtain fast and accurate registration estimates.  ...  Contact-based point measurements have been typically used to perform registration. However, a lot of time is spent in moving the robot tool to obtain these measurements.  ...  In the future we plan to compensate for this deformation using simultaneous force and position measurements as shown in [19] .  ...

Complementary model update: A method for simultaneous registration and stiffness mapping in flexible environments

Rangaprasad Arun Srivatsan, Elif Ayvali, Long Wang, Rajarshi Roy, Nabil Simaan, Howie Choset
2016 2016 IEEE International Conference on Robotics and Automation (ICRA)  
In this paper we present an approach for simultaneous registration and stiffness mapping using blind exploration of flexible environments.  ...  During contact-based exploration of flexible environments, the physical interaction with the environment can induce local deformation, leading to erroneous registration if not accounted for.  ...  An iterated extended Kalman filter (IEKF) was used to simultaneously estimate the registration parameters and generate a stiffness map of the environment.  ...
