EVALUATION OF CONTROL ALGORITHMS ON MOBILE ROBOTS FOR COLLISION AVOIDANCE

Published in ASME 2020 International Mechanical Engineering Congress and Exposition (IMECE2020), 2020

This paper describes the implementation of various algorithms to control the distance between a lead vehicle and a following (ego) vehicle. The ego robot equipped with a monocular camera and a rotating laser sensor(LDS). The outputs of the camera and laser sensor(LDS) were fused to obtain accurate distance measurements for the lead vehicle. Kalman Filter was used to implementing sensor fusion by combining perception data from the monocular camera and LDS for accurate position and velocity estimation. The results show that the Model Predictive Control (MPC) yields faster response times when compared to Proportional (P) control and Proportional-Integral (PI) control. These algorithms evaluated during constant velocity and constant acceleration of the lead vehicle.

Different control strategies for Mobile Robots

Published in Department of Mechanical Engineering, University of Washington, Seattle, 2019

In this research, the following (ego) vehicle was maintaining a safe relative distance by varying the velocity through different controllers to catch up with the lead vehicle. Two major sensors were used, a rotating Laser Distance Sensor (LDS) and an RGB camera sensor. The camera sensor operated as a secondary system and was used to improve the detection probability of the lead vehicle. A sensor fusion algorithm was used for localizing the ego vehicle which includes a detection clustering algorithm and a Kalman filter to estimate the relative distance between the two vehicles. The sensors were calibrated for the test conditions to obtain detections with in feasible limits. Different controllers such as Proportional, Proportional-Integral, and Model Predictive Control were implemented and validated both in simulation and experiment on the turtlebot3-burger robot.

PERFORMANCE ANALYSIS OF AN AIR OPERATED MICROTURBINE

Published in Journal of Sustainable Manufacturing and Renewable Energy 3, 2015

This paper is about the performance analysis of an microturbine which we developed to scavange the waste energy through compressed exhaust gas and generate electricity. This was the initial iteration product of an impulse microturbine. This had efficiency of 4 to 5 percent. After so many iterations in design, its efficiency would increase and can be use as a small portable energy generating device.
