Jeremy Fielding has come up with a handy video introducing the concept of motor types, power, and references to how to wire, speed control, and use all the common types of motors with a focus on reusing motors salvaged from appliances and other sources. Steppers, BLDC, PMDC, single and three phase, universal motors, and more.
We typically imagine robots looking like humans, but there’s a real advantage to other “form factors” that mimic pack animals.
For example, check out this new robot that MIT just made: a mini cheetah robot, the first four-legged robot to do a backflip.
At only 20 pounds the limber quadruped can bend and swing its legs wide, enabling it to walk either right side up or upside down. More practically, the robot can also trot over uneven terrain about twice as fast as an average person’s walking speed.
The Robot Operating System – also called ROS – is a framework for building Robotics applications. ROS is supported by a large community, which have built thousands of nodes – individual robot behaviors which can be composed into complex solutions. This ecosystem has been enabled on Windows. Learn how to get started, some of the differences and some of the reasons you’d want to use Windows over other operating systems. Check out the get started guide: https://aka.ms/ros
Agility Robotics shows off their progression of increasingly complex walking strategies from ATRIAS through recent results with Cassie the robot. Specifically, Cassie’s controller now includes planned footstep placements in addition to dynamic balancing, which allows access to substantially more complicated terrains.
BBC Click explores how an exoskeleton can help with physical rehabilitation, foldable phones, fashion, and visual effects.
MIT’s Cheetah 3 robot can now leap and gallop across rough terrain, climb a staircase littered with debris, and quickly recover its balance when suddenly yanked or shoved, all while essentially blind.
BBC Click explores how robots are about to change the face of retail.
In this first of a series on automation of work via AI and robotics, NeoScribe explores the current state of the art in automating fast food jobs.
Yes, you read that right. Robots rapping. Here’s a fun video set to the tune of Rapper’s Delight that explains some of the research in combining AI with robotics. The Sugar Hill Gang would be proud.
