Tomorrow's doctors will learn to check prostates using a robotic anus

When you consider the many varied tasks robots are suited to perform, one application no amount of Terminator viewings will prepare you for is the concept of brushing up on your prostate exam technique using a robotic anus.

But that’s exactly what Dr. Fernando Bello and Dr. Alejandro Granados have invented — courtesy of a new robotic rectal technology that’s designed to give medical students a realistic model to practice on, and to use in generating real-time data for trainers.

“What we’ve created is a simulator which combines robotics and haptics technology to create a physical model, alongside virtual reality where 3D rendering is used to replicate the internal anatomy,” Dr. Fernando Bello told Digital Trends. “It’s a way that both the trainee and trainer can see what their fingers are doing inside the subject at any particular moment, and get real-time feedback.”

The robot is able to measure the force that is being applied during an examination: revealing to the trainer if a junior doctor is pressing too hard, not hard enough, or failing to provide a full examination of the rectum.

Dr. Bello told Digital Trends that rectal exams are tough to teach because it is difficult to demonstrate the technique in a clear manner. “It’s something doctors around the world struggle with because there’s no way of assessing whether or not the examination is being carried out competently or not,” he says.

At present, most junior doctors train to perform rectal exams using either a basic plastic or silicone model, or by asking patients to give consent for a real-life examination. Neither of these solutions are perfect, however, since the former is not detailed enough, while the latter is not appropriate for repeated practice.

The Imperial College robot may therefore be the answer to would-be proctologists’ dreams. It replicates the feel of a rectum, using silicone and tiny robotic arms to simulate the shape, feel and pressure of the back passage. The shape and geometry of the robotic rectum was achieved by scanning volunteers using an MRI scanner. The robot can even recreate different types of anatomy — taking into account both normal and abnormal prostate conditions.

At present, Dr. Bello and Dr. Alejandro Granados have received funding to manufacture a market-ready prototype of their creation. Should all go to plan, we can expect similar robot rectums to start appearing in medical schools around the world in the not-too-distant future.

Now we just need to cross our fingers and hope Skynet doesn’t hold this against us when its army of killer robots eventually takes over!

Finishing touch: How scientists are giving robots humanlike tactile senses
A woman's hand is held by a robot's hand.

There’s a nightmarish scene in Guillermo del Toro’s 2006 movie Pan's Labyrinth in which we are confronted by a sinister humanoid creature called the Pale Man. With no eyes in his monstrous, hairless head, the Pale Man, who resembles an eyeless Voldemort, sees with the aid of eyeballs embedded in the palms of his hands. Using these ocular-augmented appendages, which he holds up in front of his eyeless face like glasses, the Pale Man is able to visualize and move through his surroundings.

This to a degree describes work being carried out by researchers at the U.K’.s Bristol Robotics Laboratory -- albeit without the whole terrifying body horror aspect. Only in their case, the Pale Man substitute doesn’t simply have one eyeball in the palm of each hand; he’s got one on each finger.

China has built a robot restaurant for next month’s Winter Olympics to help minimize contact as part of measures to reduce coronavirus infections at the event.

But banish from your mind any thoughts of some wheel-based android trundling up to your table with a tray holding your meal. The one installed for athletes and media personnel attending the Beijing Winter Games uses complex robotic technology for the entire process, from kitchen to table.

How time of day affects learning ability, and how to use it to your advantage
brain with computer text scrolling artificial intelligence

In an age where all the world's information is just a couple clicks away, it's now possible to learn practically anything at any time of day -- at least in theory. In practice, things aren't so clear-cut. Despite the fact that we can access information whenever we want, our ability to absorb and understand that information isn't quite as flexible. As it turns out, certain times of day are better for learning than others.

This is thanks to a complex array of physical processes, known as circadian rhythms, which regulate the timing of everything from our sleep to our digestion on a 24-hour cycle. They are also integral to how we process and retain information.
