Reducing Inaccuracies in Force/Haptic Feedback Systems

This novel algorithm automatically compensates for the errors introduced by physical factors, enabling the control system to Adjust the applied force accurately.

Researchers at NASA's Armstrong Flight Research Center have developed a new technology to reduce inaccuracies in force/haptic feedback devices and systems. Used at NASA in aircraft simulations for force feedback pilot controls, these systems involve a servo motor applying precise force to a specific point based on very accurate measurements. However, because the force instrumentation often cannot be placed directly at the point of interest, a mechanical assembly is used, linking the force transducer to the target point. Unfortunately, this mechanical assembly introduces inaccuracies due to its own forces of gravity, friction, and inertia.

Origami-Inspired Robot Can Ride with a Rover

The Pop-Up Flat Folding Explorer Robot (PUFFER) that’s in development at NASA’s Jet Propulsion Laboratory in Pasadena, CA, was inspired by origami. It travels with a rover, and its lightweight design can flatten itself, tucking in its wheels and crawling into places rovers can’t fit.

Eliminating Blind Spots in Commercial Trucking with IoT

Technology is becoming a critical business tool for truck manufacturers, fleet operators, and service centers. On-board diagnostics and telematic systems are a first step, but only provide a singular view and limited scalability. A more comprehensive view of truck health delivers reliability, improved uptime, and faster repairs; but this requires examining a larger and richer set of engine data together with external sources.

Fundamentals of Wire, Cable, and Connectivity

Continuous supply of electric power or faultless data transfer, provided mostly through wiring, are primary requirements affecting virtually all systems. This results in stringent requirements for production, installation, and operation of cables.

Smart Cameras

EVT (Karlsruhe, Germany) offers three ZYNQ platforms for the EyeVision machine vision software. The systems are based on a DualCore ARM with FPGA. The EyeCheck ZQ smart camera features a 20 x 20 50 mm housing size, an S-Mount adapter and 10 freely programmable IOs and interfaces such as Ethernet, RS485 and CAN. In cases where space is not limited, a bigger ZYNQ smart camera can be used, such as a camera of the EyeCheck 4xxx, or EyeCheck 9xxx series. With a C-Mount lens adapter and more I/O interfaces the cameras are suitable for almost all applications. Also because of the C-Mount adapter all C-Mount lenses can be used: telecentric, endocentric, and hypercentric lenses.

Fast-Tracking Advanced Driver Assistance Systems (ADAS) and Autonomous Vehicles Development with Simulation

ADAS and autonomous vehicles will soon be transforming our world. Due to the complexity of this immense engineering challenge, manufacturers now realize producing a reliable autonomous vehicle requires millions of miles of road testing—as onboard computers must be trained, not programmed. A seemingly impossible task.

Six-Legged Robots Move Faster with Bipod Gate

Researchers have discovered a faster and more efficient gait, never observed in nature, for six-legged robots walking on flat ground. Bio-inspired gaits, which are less efficient for robots, are used by real insects because they have adhesive pads to walk in three dimensions. (Credit: EPFL/Alain Herzog)

Researchers in Lausanne, Switzerland have determined that a bipod gait is the fastest and most efficient way for six-legged robots to move on flat ground, provided they don’t have the adhesive pads used by insects to climb walls and ceilings. This suggests designers of insect-inspired robots should make a break with the nature-inspired tripod-gait paradigm.

Will telepresence drones take off?

This week’s Question: According to a recent application made public last week, Google is hoping to patent a "mobile telepresence system." The proposed drone is designed for collaboration with colleagues from remote locations. The technology will fly indoors and move from room to room, adjusting to unpredictable floor plans. What do you think? Will telepresence drones take off?
