New planetary BLDC gearmotors: High torque and compact design
Bodine Electric Company introduces the new type 22B4-60P planetary gearmotor. This integral gearmotor combines Bodine's high-performance type 22B brushless DC motor with the new 60P (60-mm) planetary gearhead. It is ideal for applications that require higher torque than conventional helical/spur gearheads of a similar size can provide, and where a very low backlash gearhead is not required. Typical applications include conveyors, pumps, packaging, industrial automation, and a wide range of solar- or battery-powered equipment.
Compact brushless DC servo motor with integrated controller
Nanotec has developed the compact PD2-C-IP, a brushless DC servo motor with integrated controller and 42-mm flange size for use in harsh environmental conditions (class IP65). The PD2-C-IP is available as a brushless DC motor, with an operating voltage of 12 V to 48 V and a rated power of 105 W, and as a stepper motor with a nominal torque up to 0.5 Nm. Due to the field-oriented control based on an integrated encoder, both motors are controlled in the same way and differ only in their working point. Each motor is available in a USB or CANopen version. They offer effective and economical drive solutions when high precision and maximum benefit are required.

The initial system setup is already complete, so end users can get parts moving in a reliable and repeatable manner. Motion Box incorporates the Q-Motion Controller from Mitsubishi Electric, which features four-axis motion control, energy-efficient drivers, integrated I/O and network access, and a clean, efficient HMI setup.
High-torque rotary voice coil actuators
H2W Technologies has developed several high-torque rotary voice coil actuators, otherwise known as a limited angle torque motors (LATs). The model TWR-015-346-2RC was designed to allow for a low moving mass (68 grams per coil) and inertia, as well as dual independent coils to allow for two independent motion profiles or couple the coils together to double the torque output. This rotary voice coil actuator can generate a continuous torque of 185 in.-oz (1.29 Nm) and a peak torque of 555 in.-oz (3.88 Nm) at a duty cycle of 10% (i.e., 1 sec on and 9 sec off) in each coil on a 4-in. (102-mm) rotation arm. By coupling the coils, the continuous torque doubles. Applications include driving a gimbal axis in scanning applications and providing stabilizing torques for image stabilization.

With encoder feedback and advanced control loops that incorporate servo control, StepSERVO Integrated Motors provide a motion control system that operates faster, cooler, and quieter than competitive technology. The three model series (TSM, SSM, and TXM) support different options for step and direction, streaming commands, fieldbus communications, and stored Q programming for standalone operations.
Minimizing noise in electric linear motion systems
Under most circumstances, electric linear motion systems are quiet. They certainly don’t create the hissing and bang-bang noises associated with pneumatic systems. However, there’s another type of noise that comes with electric systems of all types: electrical noise or interference. The results can be anything from erratic movements to complete system failure. Patrick Hobart from Tolomatic runs through best practices for minimizing noise in these automation systems.

Game of drones? Video games to help Navy recruit unmanned systems operators

Can a video game help the U.S. Navy find future operators for its remotely operated, unmanned vehicles (UxV), popularly called drones?
To find out, the Naval Aerospace Medical Institute and Adaptive Immersion Technologies, a software company, are developing a computer game to identify individuals with the right skills to be UxV operators. The project, sponsored by the Office of Naval Research (ONR), is called StealthAdapt.
"The Navy currently doesn't have a test like this to predict who might excel as UxV operators," said Lt. Cmdr. Peter Walker, a program officer in ONR's Warfighter Performance Department. "This fast-paced, realistic computer simulation of UxV missions could be an effective recruitment tool."
Since the wars in Afghanistan and Iraq began, UxV have played ever-larger roles in intelligence, surveillance and reconnaissance, and other missions. Consequently, there's an increasing need for well-trained UxV operators.
In recent years, the Air Force established its own formal screening process for remotely piloted aircraft operators, and the Marine Corps designated an unmanned aviation systems (UAS) career path for its ranks.
The Navy, however, doesn't have an official selection and training pipeline specifically for its UxV operators, who face challenges unique to the service. For UAS duty, the Navy has taken aviators who already earned their wings; provided on-the-job, UAS-specific training; and placed them in temporary positions.
However, this presents challenges. It's costly and time-consuming to add more training hours, and it takes aviators away from their manned aircraft duties. Finally, the cognitive skills needed for successful manned aviation can vary from those needed for unmanned operators.
StealthAdapt is designed to address this issue. It consists of a cognitive test, personality assessment, and biographical history assessment. The cognitive exam actually is the game-based component of the system and takes the form of a search-and-rescue mission. Each player's assignment is to rescue as many stranded friendly forces as possible, within a pre-set time limit, while avoiding fire from hostile forces.
If that's not stressful enough, players must simultaneously monitor chat-based communications, make sure they have enough fuel and battery power to complete missions, memorize and enter authentication codes required for safe rescue of friendlies, decode encrypted information, and maintain situational awareness.
"We're trying to see how well players respond under pressure, which is critical for success as an unmanned operator," said Dr. Phillip Mangos, president and chief scientist at Adaptive Immersion Technologies. "We're looking for attention to detail, the ability to multitask and prioritize, and a talent for strategic planning-thinking 10 moves ahead of your adversary."
To maintain this pressure, players complete multiple 5- to 10-minute missions in an hour. Each scenario changes, with different weather, terrain, number of friendlies and hostiles, and potential communication breakdowns.
After finishing the game portion, participants answer questions focusing on personality and biographical history. Mangos' team then crunches this data with game-performance metrics to create a comprehensive operator evaluation.
Last year, over 400 civilian and military volunteers participated as StealthAdapt research subjects at various Navy and Air Force training centers. Mangos and his research team currently are reviewing the results and designing an updated system for validation by prospective Navy and Air Force unmanned operators. It will be ready for fleet implementation this year.
Mangos envisions StealthAdapt serving as a standalone testing and recruitment tool, or as part of a larger screening process such as the Selection for UAS Personnel, also known as SUPer. SUPer is an ONR-sponsored series of specialized tests that assesses cognitive abilities and personality traits of aspiring UxV operators.
