A 3D-Printable Mecanum Wheeled Robot Platform

If your interest lies with robotics there are a multitude of different platforms for you to build. [Teemu Laurila] was frustrated with what was on offer, so designed his own with four-wheel double wishbone suspension and mecanum wheels for maximum flexibility.

It’s a design that has been through multiple revisions since its first iteration in 2015, and along the way it’s clear some thought has gone into it. That double wishbone suspension features an angle for a high ground clearance, and is fully sprung. Drive comes from small motor/gearboxes at each axle. The chassis meanwhile has plenty of space for a single-board computer, and has been specifically designed with the BeagleBone Black in mind.

This build isn’t fully DIY, as the mecanum wheels appear to be off-the-shelf items, but the rest of the project makes up for this. If you need to make your own, it’s hardly as though there aren’t any projects from which you can borrow components.

Brain-controlled prosthetic hand to become reality

Imagine a patient controlling the movement of his or her prosthetic limb simply by thinking of commands. It may sound like science fiction but will soon become reality thanks to the EU-funded DeTOP project. A consortium of engineers, neuroscientists and clinicians has made great strides in further developing the technology behind more natural and functional prostheses.

The team uses an osseointegrated human-machine gateway (OHMG) to develop a physical link between a person and a robotic prosthesis. A patient in Sweden was the first recipient of titanium implants with the OHMG system. The OHMG is directly fitted to bones in the user’s arms, from which electrodes to nerves and muscle extract signals to control a robotic hand and provide tactile sensations. According to a news item by “News Medical,” the patient will begin using a training prosthesis in the next few months before being fitted with the new artificial hand developed by DeTOP partners. This will help the team evaluate the entire system, including the implanted interface, electronics, as well as wrist and hand functions. Motor coordination and grip strength will also be assessed during the tests.

How hospitals are using AI to save their sickest patients and curb ‘alarm fatigue’

From interpreting CT scans to diagnosing eye disease, artificial intelligence is taking on medical tasks once reserved for only highly trained medical specialists — and in many cases outperforming its human counterparts.

Now AI is starting to show up in intensive care units, where hospitals treat their sickest patients. Doctors who have used the new systems say AI may be better at responding to the vast trove of medical data collected from ICU patients — and may help save patients who are teetering between life and death.

This Robotic Arm Inspired by Luke Skywalker Has Allowed an Amputee to Feel Again

Research on robotic prostheses is coming along in leaps and bounds, but one hurdle is proving quite tricky to overcome: a sense of touch. Among other things, this sense helps us control our grip strength — which is vitally important when it comes to having fine motor control for handling delicate objects.

Enter a new upgrade for the LUKE Arm — named for Luke Skywalker, the Star Wars hero with a robotic hand. Prototype versions of this robotic prosthesis can be linked up to the wearer’s nerves.

And, thanks to biomedical engineers at the University of Utah, for the participants of their experimental study, the arm can now also produce an ability to feel. This spectacular advance allowed one wearer to handle grapes, peel a banana, and even feel his wife’s hand in his.

Why ‘upgrading’ humanity is a transhumanist myth

Click on photo to start video.

Though some computer engineers claim to know what human consciousness is, many neuroscientists say that we’re nowhere close to understanding what it is — or its source.

In this video, bestselling author Douglas Rushkoff gives the “transhumanist myth” — the belief that A.I. will replace humans — a reality check. Is it hubristic to upload people’s minds to silicon chips, or re-create their consciousness with algorithms, when we still know so little about what it means to be human?

You can read more about Rushkoff’s perspective on this issue in his new book, Team Human.

In the last video in this series, we started on a quest to clear up the misconceptions between artificial intelligence and machine learning, beginning with discussing supervised learning, an essential foundational building block in understanding the modern field of machine learning.

The focus of this video then will continue right were the last one left off, so sit back, relax and join me once again in an exploration into the field of machine learning — more specifically, unsupervised learning!
