Safety-Critical Scenario Generation Via Reinforcement Learning Based Editing

ICRA 2024poster

Generating safety-critical scenarios is essential for testing and verifying the safety of autonomous vehicles. Traditional optimization techniques suffer from the curse of dimensionality and limit the search space to fixed parameter spaces. To address these challenges, we propose a deep reinforcemen…

CuRobo: Parallelized Collision-Free Robot Motion Generation

ICRA 2023poster

This paper explores the problem of collision-free motion generation for manipulators by formulating it as a global motion optimization problem. We develop a parallel optimization technique to solve this problem and demonstrate its effectiveness on massively parallel GPUs. We show that combining simp…

VaPr: Variable-Precision Tensors to Accelerate Robot Motion Planning

IROS 2023poster

High-dimensional motion generation requires nu-merical precision for smooth, collision-free solutions. Typically, double-precision or single-precision floating-point (FP) formats are utilized. Using these for big tensors imposes a strain on the memory bandwidth provided by the devices and alters the…
