Modular Climbing Robot Splits into Multiple Explorer Bots

A prototype of the Detachable Compliant Modular Robot (DCMR).

Researchers from the Robotics Research Centre at the International Institute of Technology – Hyderabad (IIIT-H), have developed a stair and obstacle climbing robot that can disassemble itself into smaller robots, and then reassemble back into one device. As a composite system, the Detachable Compliant Modular Robot (DCMR) can climb steep obstacles and staircases, and explore uneven terrain. When it detaches into multiple robots, it can explore cramped spaces, traverse flat terrain, and behave as a Multi Agent System (MAS).

In an effort to make digital smartwatches more convenient for users, researchers at Dartmouth College and the University of Waterloo have produced a prototype watch face named Cito that moves in five different directions. With the ability to rotate, hinge, translate, rise, and orbit, the model improves functionality and addresses some of the limitations of today’s fixed-face watches.

Mechanical Actuators Bend as They “Breathe”

Extreme temperatures can severely strain a mechanical component because its material may have trouble enduring the heat without degrading. To address the problem, researchers at MIT developed a new material that expands and contracts as it lets oxygen in and out. The result is a new way to make actuators that could be used in extremely hot environments.

Design Considerations for Overmolding and Insert Molding

Overmolding is regularly used to manufacture multi-material components for applications in a variety of industries: medical, automotive, electronics, and more. But it’s only recently that it also became a viable and cost-effective prototyping method. This white paper offers a primer on overmolding and insert molding and how these methods can be used for both prototyping and production.

NSK MOTORIZED BALL SCREW ACTUATOR (MBSA SERIES): NSK Achieves Space Saving Design with Linear Precision for Medical Applications

NSK Americas examines how advancements in technology have reduced equipment size used for medical applications. Contributing to this trend, NSK has developed the MBSA Series (motorized ball screw actuator). The new design eliminates the need for a separate motor-to-ball screw coupling. The compact space-saving design reduces system inertia and eliminates alignment error that can occur when the motor and ball screw are separately mounted. Not only is the new design compact, but it’s also precise. NSK uses a precision ground ball screw versus the traditional lead screw option. This white paper details why a precision ground ball screw is the optimal solution.

Commercial Drones: High-Tech Toy or Security Risk?

Although radio controlled drones provide beneficial “eye in the sky” services such as search and rescue, they also raise serious privacy and safety concerns. The growing number of affordable drones capable of carrying payloads of 100 grams up to a few kilograms has resulted in the need for effective detection and monitoring solutions.

Applying Wiring Harness Changes Without Damaging Your Electric System Design Flow

When an engineering change must be made to a wiring harness—and let’s face it, there is always going to be late-stage changes—it means you will make a change in multiple design steps. This Tech Talk discusses the challenges of applying changes and how to better handle them. For example, you might need to change an electric component that drives more current than the previous one. A change such as this can cause issues throughout your design flow: System Design, Wiring Design, and the Harness Design. The resulting inconsistencies lead to poor quality and prevent you from achieving your design cycle goals.

Fiber Optic Rotary Joints Add a Spin to Sensing, Mobile, and Robotic Fiber Systems

To the passing optical signals, fiberoptic rotary joints (FORJs) are nothing more than fiber connectors, which provide connection between one or multiple fibers. Their unrestricted ability to rotate, however, gives them a critical role in many sensing, mobile, and robotic fiber systems such as ROVs (remotely operated vehicles), aerostat radars, submarines, satellite antennae, OCT (optical coherence tomography), mining vehicles, cranes, wind turbines, robotic vehicles, broadcasting (mobile cameras), etc. This article discusses some of the applications where optical rotary joints are indispensable.
