By minimizing the acceleration of industrial robots, energy consumption can be reduced by up to 40 percent — while retaining the given production time. This is the result of a new optimization algorithm that was developed by researchers at Chalmers University of Technology. Optimization of the robot’s movements reduces acceleration and deceleration, as well as the time the robot is ... Read More »

Researchers at Harvard have developed faster actuators that might speed up soft robots. Existing soft robots must move large amounts of liquid or gas, resulting in slow movements. The new approach takes advantage of snap-through instabilities: big changes that are instantly triggered by small changes. Normally, snap-through instabilities are associated with mechanical failure, thought to be uncontrollable, and avoided. This ... Read More »

Robi the Subscription-based Robot

This little two-pound robot is sent in pieces, over an 18-month period. It's up to you to put him together. (Photo credit: De Agostini Publishing USA.)

A Professor from the University of Tokyo is selling robots, piece by piece, to those willing to pay for an subscription. For $89.99 per month (plus shipping and handling), subscribers get parts and a full color manual explaining how to build each part of the bot. At the end of the 18-month subscriptions, subscribers will have put together all the ... Read More »

LERN: 3D Imaging Technology that Works in Bright Light

A depth-sensing camera can create a 3-D image of an object, even if it is in bright light. (Photo credit: CMU.)

Researchers in Canada and the US have developed a new 3D imaging technology that — unlike other depth sensing systems — can work in bright light, because it only gathers the light it actually needs to create the image. Invented by researchers at Carnegie Mellon University and the University of Toronto the system uses a mathematical model that optimizes the ... Read More »

SparkFun Snappable Protoboard

Not all projects need the same size protoboard. Customize your next robot with Sparkfun’s Snappable Protoboard. The board has been intentionally scored between each column and row of holes, so that it’s easy to snap in to pieces by bending it along the edge of a sturdy, sharp tool. No need to use a rotary tool or sheet metal break ... Read More »

LERN: Borrowing Human Reflexes for a Bot

MIT PhD student Joao Ramos demonstrates a Balance Feedback Interface system on HERMES.

Researchers at MIT have developed a robotic system that uses a human operator’s innate balancing ability to stop the robot from falling over after an impact. An exoskeleton worn by the human calculates the person’s movements as forces are unexpectedly applied to the robot and human simultaneously. The robot is programmed to mimic the human’s movements as he balances after ... Read More »

Light Up Flower Craft for Kids

Looking for a fun, easy way to explore STEM basics with young children? Check out the E-Flower Kit from Soldering Sunday. Children as young as 8 have completed this craft in a half an hour, while learning about LEDs, batteries, and circuits. (Note that this kit should not be used around children who are still mouthing objects, as it does ... Read More »

LERN: Robotic Whiskers Generate Tomographic Images

Seals use whiskers to hunt fish in the dark. Similarly, a team of researchers hope their Nitinol whiskers will improve robotic navigation. (Photo credit: Institute of Physics)

A new sensor inspired by mammalian whiskers can generate tomographic images measuring fluid flow. Scientists at the University of Illinois at Urbana-Champaign and Illinois’ Advanced Digital Sciences Centre in Singapore were inspired by the way many animals use their whiskers to navigate in the dark. “When it is dark, whiskers play a key role for animals in exploring, hunting or ...

LERN: New Self-Specialization Algorithm Explored

The robots were tasked with completing a task similar to that performed by Atta leafcutter ants. (Photo credit: PLOS)

New research suggests that teams of robots that self-specialize to perform specific tasks using a novel evolutionary method might have an advantage when completing missions. The study involved robotic simulations modeled loosely after the activity of leaf cutter ants that cut leaves off trees to use in their nests. Simulated MarXbots had to collect items, take them down a slope ... Read More »
