Plastic Cam Follower and Rollers Improve Motion System Performance
When designing motion systems that require rollers or cam followers, many engineers still believe that only all-metal components will fit the bill. Yet cam followers and rollers with polymer bearing surfaces have emerged as a high-performance alternative to traditional metal motion components. Sized as drop-in replacements for standard inch and metric-sized metal rollers, composite cam followers and rollers offer some compelling technical advantages -- including reduced maintenance costs, improved performance and extended lifecycle. www.intechpower.com
Download the paper today and learn how plastics can improve your cam- and roller-driven motion systems.

New movie-making drones autonomously shoot cinematography on the fly
In recent years, a host of Hollywood blockbusters including “The Fast and the Furious 7” and “Jurassic World” have included aerial tracking shots provided by camera-carrying drone helicopters, requiring separate operators for the drones and the cameras, and careful planning to avoid collisions. Now, a team of researchers from MIT and ETH Zurich hopes to make drone cinematography more accessible, simple, and reliable.

Air spray: The comeback of stunning military aircraft paint jobs
Eight Oregon Air National Guard members received a call to arms. Their wing commander handed them an assignment, stressing high priority. They worked 33 consecutive days, some pulling night shifts. Their orders: Paint a Boeing-built F-15 Eagle jet fighter in a manner that would elevate base morale at Kingsley Field in Klamath Falls, OR, and commemorate the Air National Guard’s 75th anniversary across the state.

Image - Torque Feedback for Electric Servo Motors
Torque Feedback for Electric Servo Motors
Automated systems in a variety of different industries rely on servomotors to monitor linear and rotational motion. To close the loop, a strain gauge-based torque sensor is necessary to provide an accurate torque measurement. By mounting the sensor onto the gearbox housing, the servomotor can be commanded to generate the required torque.

Adhesive vent for automotive
The 5-mm, low-profile AVS 110 adhesive vent from GORE is perfectly aligned with the need to further miniaturize automotive control units, sensors, actuators, and motors, and to better protect these high-value electronics from the rigors of under-hood and under-chassis environments. The vent’s 100% ePTFE all-membrane construction reliably protects against hazards such as splashes or immersions and automotive fluids. More reliable venting performance can reduce the need for heavier housings, seals, and gaskets.

Stepper motor controller delivers 2,000x basic resolution
Precision positioning systems industry leader PI (Physik Instrumente) has released a higher performance model of its successful Mercury Stepper Motion controller. Stepper motors take up discrete positions in a revolution of a constant distance. Typical commercial models provide 200 to 1,000 full steps per revolution. Designed to deliver more than 2,000 times the basic motor resolution, the C-663.12 Mercury controller is the newest addition to PI’s suite of motion control solutions.

Image - Dual-feedback voice coil positioning stage
Dual-feedback voice coil positioning stage
The VCS20-020-CR-01-MC-F3K voice coil positioning stage can operate under closed-loop position control with force monitoring or closed-loop force control with position monitoring. It uses H2W voice coil motor NCC20-18-020-1A to generate a continuous/peak force of 2 lb (8.9 N)/6 lb (26.7 N) with a total stroke length of 2 in. (50.8 mm). The 1-micron resolution encoder allows for precise positioning. The 3-kg rated force transducer allows for 0.01- to 3-kg of push/pull force feedback control. It comes supplied with a high-accuracy crossed roller bearing. The motor coil is the moving part of the assembly in order to reduce the moving mass of the system. Power is supplied to the motor via a high-flex, high-reliability flat ribbon cable.

Micro gripper for small, fragile part assembly
The MGR5 electric micro gripper from SMAC was designed for small, fragile part assembly. It features a light-force capability of 10 g or less and a soft-land capability for pick and place of delicate parts. Each jaw can be independently controlled in force, position, and velocity, with a 5-micron linear encoder standard (1 micron optional). Ideal for a wide range of positioning, measuring, and inspection applications, particularly where 100% verification is required.

New way to clear pollutants from water
When it comes to removing very dilute concentrations of pollutants from water, existing separation methods tend to be energy and chemical intensive. Now, a new method developed at MIT could provide a selective alternative for removing even extremely low levels of unwanted compounds -- and it can do it using very little energy.

Can a robo dog fetch you a cold one? Impressive!
If you haven't seen the all-electric SpotMini robot from Boston Dynamics yet, well, hold on to your hat. Or better yet, let this incredibly nimble droid (complete with extra arm) hold it for you. It runs, walks, scoots, and shimmies effortlessly and quietly for about 90 minutes on a single charge, depending on what it is doing. It has a variety of sensors, including depth cameras, a solid-state gyro, and proprioception sensors in the limbs, to help with navigation and mobile manipulation. SpotMini performs some tasks autonomously, but often uses a human for high-level guidance. We're sure you could train it to fetch from the fridge.
