The University of Maryland’s Perception and Robotics Group(PRG) has developed EVDodgeNet, a dynamic obstacle avoidance system for quadrotor UAVs (unmanned aerial vehicles) that uses event cameras as sensors. EVDodgeNet is a deep learning-based solution for dodging multiple dynamic obstacles on a quadrotor with a single event camera and on-board computation.

The purpose of this project is to create a scaled model of an autonomous car crash avoidance system. The project is a continuation of two projects, the 2010 “Autonomous Crash Avoidance System” senior project and the 2012 “A Model Predictive Control Approach to Roll Stability of a Scaled Crash Avoidance Vehicle” master’s thesis.

Feb 07, 2018 · A video drone recorded the event from overhead. The test result was drama-free. According to an indicator on the dashboard, the car’s stereo cameras and radar sensors detected me from a long distance away and the car slowed gradually, well before it needed to. It matched my speed and followed for a short time before I turned off the track.

Oct 10, 2018 · The state mechanism involves four sequentially event-triggered steps depending on the conditions defined as follows: 1. Step 1: attitude stabilization: only the attitude controller is turned on with (0, 0, 0) as the required attitude on the three rotational axes (roll, pitch, and yaw) and the thrust is kept constant at to compensate for gravity.
