Low-cost, Lightweight Electronic Flow Regulators for Throttling Liquid Rocket Engines

no code implementations15 Jan 2024 Vint Lee, Sohom Roy

Our design is simple, low-cost and robust: with a single ball valve actuated by a motor, we regulate both gaseous pressurant and cryogenic liquid propellant at high flow rates (1. 14 kg/s of liquid; 0. 39 kg/s of gas) and upstream pressures (310 bar).

DreamSmooth: Improving Model-based Reinforcement Learning via Reward Smoothing

no code implementations2 Nov 2023 Vint Lee, Pieter Abbeel, Youngwoon Lee

Model-based reinforcement learning (MBRL) has gained much attention for its ability to learn complex behaviors in a sample-efficient way: planning actions by generating imaginary trajectories with predicted rewards.
