A set of five tiny fundamental parts can be assembled into a wide variety of functional devices including a tiny “walking” motor that can move back and forth across a surface or...
In the digital age, the measurement of rotation of a mechanical shaft on a motor or a rotating instrument knob needs to be done quickly and efficiently....
A smartphone app was developed that allows a user to easily program any robot to perform a mundane activity such as picking up parts from one area and delivering them to another. The app, called VRa, uses...
maxon precision motors (Taunton, MA) released the EC-i30 20W brushless servomotor with integrated electronics. With an integrated 4-quadrant speed controller, the motor...
Antenna characterization techniques are often expensive and time-consuming. NASA’s Glenn Research Center developed a highly versatile and automated system to perform characterization of single or multiple small circuit antennas, printed on-wafer or on other substrates, by measuring the antenna’s...
The Advanced Explosive Ordnance Disposal Robotic System (AEODRS) features a modular open systems architecture that enables the robot to be self-righting after a fall. The self-righting...
Conventional pistons are made of a rigid chamber and a piston inside that can slide along the chamber’s inner wall while at the same time maintaining a tight seal. As a result, the piston...
There is great potential in using both drones and ground-based robots for situations like disaster response, but generally these platforms either fly or creep along the ground. The flying...
PI, L.P. (Auburn, MA) offers the L-505 miniature linear translation stages for precision motion, alignment, and positioning applications where space is...
Stepper motors and stepper-based linear actuators are often selected for open-loop motion control devices and equipment. These can be found in a wide range of products and...
A new approach developed at MIT to building robots is based on a set of five millimeter-scale components, all of which can be attached to each other by a standard connector. Using this simple kit...
A high-sensitivity and low-noise MEMS accelerometer was developed using multi-layer metal structures composed of multiple metal layers. The accelerometer achieves 1 µG level...
NB Corporation of America (Hanover Park, IL) released a rotary ball spline that can be used for both rotational and linear motion. Applications include SCARA robots, the...
An ultra-low-power hybrid chip inspired by the brain could help give palm-sized robots the ability to collaborate and learn from their experiences. Combined with new generations of...
NASA Goddard Space Flight Center developed gear bearing technology that combines gear and bearing functions into a single unit that significantly improves gear drives for electrical, internal combustion, and turbine motors. The...
This technology was developed to address the limitations of traditional, single-fed linear alternators that require permanent magnets, adhesive bonding organics, and heavy iron laminations for flux control. They experience eddy-current losses and require electromagnetic interference protection. Furthermore,...
Electromagnetic motors typically convert electrical energy into rotational mechanical energy and are employed across a wide array of applications. While motors represent relatively mature technology, practitioners continue to seek ways to enhance motor operation including a decrease in cost, drop in size/weight,...
