Group Surfing: A Pedestrian-Based Approach to Sidewalk Robot Navigation

Yuqing Du, Nicholas J. Hetherington, Chu Lip Oon, Wesley P. Chan, Camilo Perez Quintero, Elizabeth Croft +1
ICRA 2019poster

In this paper, we propose a novel navigation system for mobile robots in pedestrian-rich sidewalk environments. Sidewalks are unique in that the pedestrian-shared space has characteristics of both roads and indoor spaces. Like vehicles on roads, pedestrian movement often manifests as linear flows in…

Robot Programming Through Augmented Trajectories in Augmented Reality

Camilo Perez Quintero, Sarah Li, Matthew KXJ Pan, Wesley P. Chan, H.F. Machiel Van der Loos, Elizabeth Croft
IROS 2018poster

This paper presents a future-focused approach for robot programming based on augmented trajectories. Using a mixed reality head-mounted display (Microsoft Hololens) and a 7-DOF robot arm, we designed an augmented reality (AR) robotic interface with four interactive functions to ease the robot progra…

Flexible virtual fixture interface for path specification in tele-manipulation

Camilo Perez Quintero, Masood Dehghan, Oscar Ramirez, Marcelo H. Ang, Martin Jagersand
ICRA 2017poster

We present the design and implementation of a flexible force-vision-based interface; allowing local operators to visually specify a path constraint to a remote robot manipulator in an on-line fashion during the teleoperation. Using bilateral and unilateral configurations, we compare our system to di…

Real-time salient closed boundary tracking via line segments perceptual grouping

Xuebin Qin, Shida He, Camilo Perez Quintero, Abhineet Singh, Masood Dehghan, Martin Jagersand
IROS 2017poster

This paper presents a novel real-time method for tracking salient closed boundaries from video image sequences. This method operates on a set of straight line segments that are produced by line detection. The tracking scheme is coherently integrated into a perceptual grouping framework in which the…

ViTa: Visual task specification interface for manipulation with uncalibrated visual servoing

Mona Gridseth, Oscar A. Ramirez, Camilo Perez Quintero, Martin Jägersand
ICRA 2016

We present a human robot interface (HRI) for semi-autonomous human-in-the-loop control, that aims to tackle some of the challenges for robotics in unstructured environments. Our HRI lets the user specify desired object alignments in an image editor as geometric overlays on images. The HRI is based o

On-line reconstruction based predictive display in unknown environment

Huan Hu, Camilo Perez Quintero, Hanxu Sun, Martin Jagersand
ICRA 2015poster

In tele-robotics, time delay is a significant problem. When video feedback is delayed, operators adopt inefficient move-wait strategies, so system performance decreases. Predictive display (PD) is an effective solution to compensate for delays by graphics rendering of predicted visual feedback. Usin…

Tracking benchmark and evaluation for manipulation tasks

Ankush Roy, Xi Zhang, Nina Wolleb, Camilo Perez Quintero, Martin Jägersand
ICRA 2015poster

In this paper we present a public dataset to evaluate trackers used for human and robot manipulation tasks. For these tasks both high DOF motion and high accuracy is needed. We describe in detail, both the process of recording the sequences and how ground truth data was generated for the videos. The…
