Autonomous Navigation Mobile Robot Using ROS Without Using a Pre-saved Map

Autonomous Navigation Mobile Robot Using ROS Without Using a Pre-saved Map

In the previous lesson, we started with autonomous navigation using a pre-saved map, wrote our own code, and created the auto_nav package for our final project. In a nutshell, we navigated autonomously using a pre-saved mapwere introduced to autonomous navigation conceptsran Localization, move_base, and other navigation nodes Autonomous navigation of Turtlebot in ROS In this last lesson of the series of lessons on ROS tutorials, we will navigate autonomously without using a pre-saved map (actual SLAM)create the auto_nav package (part 2) Autonomous navigation of Turtlebot without a pre-saved map (actual SLAM) Let's also have a summary of the whole course:…

Localization, Mapping & SLAM Using gmapping Package

Localization, Mapping & SLAM Using gmapping Package

In the previous lesson, we downloaded the turtlebot3 simulation package, launched Gazebo and tried to understand its different features and files, and played with an actual robotics turtle. Turtlebot3 Gazebo Simulation In this lesson in the series of lessons on ROS tutorials, we will understand what localization, mapping, and SLAM mean in Robotics, we will also launch the Turtlebot3 gmapping package in Gazebo, and draw a global map using the robot's LIDAR (localization + mapping). turtlebot3 gmapping package The table of contents for the entire course: https://www.mecharithm.com/what-is-robot-operating-system-ros/ Watch the video of this lesson: Robot Operating System (ROS) learning lessons (more…

ADIBOT-A: an Autonomous Disinfection Robot

ADIBOT-A: an Autonomous Disinfection Robot

UBTECH Robotics developed an autonomous UV-C disinfection robot called the ADIBOT-A that is capable of autonomous navigation in different floor plans using U-SLAM. Image credit: UBTECH Robotics Developed in response to the COVID-19 global pandemic, the robot can be widely used as a disinfection solution in medical centers, hospitals, hotels, schools, and fitness centers. Image credit: UBTECH Robotics Key features: four PIR motions sensors can detect motion from 30 ft. awayRGBD TOF camera for 3D depth perception360 degree light coverageLIDAR, and ultrasonic sensors for better navigationautonomously navigates toward the charging dock for recharging Image credit: UBTECH Robotics Image credit: UBTECH…

Labrador Retriever Robot: an Assistive Robot for Elderly

Labrador Retriever Robot: an Assistive Robot for Elderly

Labrador Systems, a company that makes assistive home robots, recently made Labrador Retriever which is an autonomous service robot to make life easier for senior adults or people with disabilities to move or "retrieve" things at home. Image credit: Labrador Systems Initially, the robot should be trained to build a map for the home. This training is done using a set of routes and stops (places that the robot should go, such as by the fridge) based on the customer's needs and preferences. Image credit: Labrador Systems Then the robot can navigate through the home autonomously using 3D vision and…
