BDIS-SLAM: A lightweight CPU-based dense stereo SLAM for surgery
Jingwei Song, Ray Zhang, Qiuchen Zhu +2
Purpose: Common dense stereo Simultaneous Localization and Mapping (SLAM) approaches in Minimally Invasive Surgery (MIS) require high-end parallel computational resources for real-…
Proprioceptive Invariant Robot State Estimation
Tzu-Yuan Lin, Tingjun Li, Wenzhe Tong +1
This paper reports on developing a real-time invariant proprioceptive robot state estimation framework called DRIFT. A didactic introduction to invariant Kalman filtering is provid…
ConvBKI: Real-Time Probabilistic Semantic Mapping Network with Quantifiable Uncertainty
Joey Wilson, Yuewei Fu, Joshua Friesen +5
In this paper, we develop a modular neural network for real-time {\color{black}(> 10 Hz)} semantic mapping in uncertain environments, which explicitly updates per-voxel probabilist…
Iterative PnP and its application in 3D-2D vascular image registration for robot navigation
Jingwei Song, Keke Yang, Zheng Zhang +3
This paper reports on a new real-time robot-centered 3D-2D vascular image alignment algorithm, which is robust to outliers and can align nonrigid shapes. Few works have managed to…
Lie Neurons: Adjoint-Equivariant Neural Networks for Semisimple Lie Algebras
Tzu-Yuan Lin, Minghan Zhu, Maani Ghaffari
This paper proposes an equivariant neural network that takes data in any semi-simple Lie algebra as input. The corresponding group acts on the Lie algebra as adjoint operations, ma…
Human-robot Matching and Routing for Multi-robot Tour Guiding under Time Uncertainty
Bo Fu, Tribhi Kathuria, Denise Rizzo +4
This work presents a framework for multi-robot tour guidance in a partially known environment with uncertainty, such as a museum. A simultaneous matching and routing problem (SMRP)…
Optical flow-based vascular respiratory motion compensation
Keke Yang, Zheng Zhang, Meng Li +3
This paper develops a new vascular respiratory motion compensation algorithm, Motion-Related Compensation (MRC), to conduct vascular respiratory motion compensation by extrapolatin…
Convex Geometric Motion Planning on Lie Groups via Moment Relaxation
Sangli Teng, Ashkan Jasour, Ram Vasudevan +1
This paper reports a novel result: with proper robot models on matrix Lie groups, one can formulate the kinodynamic motion planning problem for rigid body systems as \emph{exact} p…
Convex Geometric Trajectory Tracking using Lie Algebraic MPC for Autonomous Marine Vehicles
Junwoo Jang, Sangli Teng, Maani Ghaffari
Controlling marine vehicles in challenging environments is a complex task due to the presence of nonlinear hydrodynamics and uncertain external disturbances. Despite nonlinear mode…
