Building a ROS Robot for Mapping and Navigation #1

Описание: Get your first 10 PCBs for free at https://www.pcbway.com/

I previously showed a demo of Turtlebot 3 doing mapping and navigation with ROS. Now it's time to attempt to built a robot from scratch and understand how ROS hangs together and which components we need to implement it all from scratch. I'm using my NERF Blaster Robot chassis to try this because it has wheel encoders and already has an Arduino on board.

In this video I've added a Raspberry Pi 4, and an RPLidar A1 which we'll look at more closely next time.

XROBOTS

Former toy designer, current YouTube maker and general robotics, electrical and mechanical engineer, I’m a fan of doing it yourself and innovation by trial and error. My channel is where I share some of my useful and not-so-useful inventions, designs and maker advice. Iron Man is my go-to cosplay, and 3D printing can solve most issues - broken bolts, missing parts, world hunger, you name it.

XRobots is the community around my content where you can get in touch, share tips and advice, and more build FAQs, schematics and designs are also available.
