Graphene may possibly be the future replacement for silicone. It's a two-dimensional material that measures just one atom thick and has a breaking strength 300 times greater than steel.
Here are three different types of rotary applications and the cable carrier system used for each.
New smaller and more portable electronics in aerospace, defense, and other stressful environments, like those encountered in robotics and oil exploration, are resulting in changing demands and designs of electronic connector systems.
For the Robotics Challenge, to demonstrate the robot's ability to operate a vehicle, DARPA chose to use the RANGER XP 900 EPS vehicles, which were all customized for the challenge with a TORC SafeStop Emergency System.

From Raspberry Pi Foundation : The compute module contains the guts of a Raspberry Pi (the BCM2835 processor and 512Mbyte of RAM) as well as a 4Gbyte eMMC Flash device (which is the equivalent of the SD card in the Pi). This is all integrated on to a small 67.6x30mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory*). The Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins. You get the full flexibility of the BCM2835 SoC (which means that many more GPIOs and interfaces are available as compared to the Raspberry Pi), and designing the module into a custom system should be relatively straightforward as we’ve put all the tricky bits onto the module itself. So what you are seeing here is a Raspberry Pi shrunk down to fit on a SODIMM with onboard memory, whose connectors you can customise for your own needs. The Compute Module is primarily designed for those who are going to create their own PCB. However, we are also launching something called the Compute Module IO Board to help designers get started.
From MinnowBoard : MinnowBoard MAX is another open hardware embedded board we've developed to serve the needs of both the professional developer and hacker/maker community. Based on Intel's new Atom Bay Trail SoC platform, it offers a new generation of performance and features, but remains petite in size and cost. Our entry-level SKU will be $99 MSRP, with additional board configuration options to be made available. All models will include 64-bit processors, USB 3.0, and Intel HD graphics with open source accelerated drivers for Linux, to just name a few of the new features! $99 MSRP: E3815 (single-core, 1.46 GHz), 1GB $129 MSRP: E3825 (dual-core, 1.33 GHz), 2GB HDMI (micro HDMI connector) 1 – Micro SD SDIO 1 – SATA2 3Gb/sec 1 – USB 3.0 (host) 1 – USB 2.0 (host) 1 – Serial debug via FTDI cable (sold separately) 10/100/1000 Ethernet The low-speed expansion port is a 2×13 (26-pin) male 0.1″ pin header. SPI, I2C, I2S Audio, 2x UARTs (TTL-level), 8x GPIO (2x supporting PWM), +5V, GND The high-speed expansion port is a 60-pin, high-density connector. 1x PCIe Gen 2.0 Lane, 1x SATA2 3Gb/sec, 1x USB 2.0 host, I2C, GPIO, JTAG, +5V, GND

From Evolving AI Lab: Here we evolve the bodies of soft robots made of multiple materials (muscle, bone, & support tissue) to move quickly. Evolution produces a diverse array of fun, wacky, interesting, but ultimately functional soft robots. Enjoy! ( full paper )
The next chapter in the industrial revolution is 3D printing, delivering a huge impact on additive manufacturing. It will not only create thousands of new jobs, but it will create many new businesses.
Essentially, we're creating drones for water that produce mapping capabilities; it's somewhat similar to air drones (i.e.: fixed wing UAVs) that map from the sky, but we're mapping from the water.
Downtime near zero vs. extended downtime of former gantry system.
Dynamixel XL-320 is a digital servo (in this case, featuring a 8-bit STM8 controller).
From John Goatstream's Vimeo Videos: We present a muscle-based control method for simulated bipeds in which both the muscle routing and control parameters are optimized. This yields a generic locomotion control method that supports a variety of bipedal creatures. All actuation forces are the result of 3D simulated muscles, and a model of neural delay is included for all feedback paths. As a result, our controllers generate torque patterns that incorporate biomechanical constraints. The synthesized controllers find different gaits based on target speed, can cope with uneven terrain and external perturbations, and can steer to target directions...

From DARPA : DARPA tasks four companies with designing new aircraft to revolutionize vertical takeoff and landing (VTOL) flight capabilities. For generations, new designs for vertical takeoff and landing aircraft have remained unable to increase top speed without sacrificing range, efficiency or the ability to do useful work. DARPA’s VTOL Experimental Plane (VTOL X-Plane) program seeks to overcome these challenges through innovative cross-pollination between the fixed-wing and rotary-wing worlds, to enable radical improvements in vertical and cruise flight capabilities. In an important step toward that goal, DARPA has awarded prime contracts for Phase 1 of VTOL X-Plane to four companies: Aurora Flight Sciences Corporation The Boeing Company Karem Aircraft, Inc. Sikorsky Aircraft Corporation “We were looking for different approaches to solve this extremely challenging problem, and we got them,” said Ashish Bagai, DARPA program manager. “The proposals we’ve chosen aim to create new technologies and incorporate existing ones that VTOL designs so far have not succeeded in developing. We’re eager to see if the performers can integrate their ideas into designs that could potentially achieve the performance goals we’ve set.” VTOL X-Plane seeks to develop a technology demonstrator that could: Achieve a top sustained flight speed of 300 kt-400 kt Raise aircraft hover efficiency from 60 percent to at least 75 percent Present a more favorable cruise lift-to-drag ratio of at least 10, up from 5-6 Carry a useful load of at least 40 percent of the vehicle’s projected gross weight of 10,000-12,000 pounds All four winning companies proposed designs for unmanned vehicles, but the technologies that VTOL X-Plane intends to develop could apply equally well to manned aircraft. Another common element among the designs is that they all incorporate multipurpose technologies to varying degrees. Multipurpose technologies decrease the number of systems in a vehicle and its overall mechanical complexity. Multipurpose technologies also use space and weight more efficiently to improve performance and enable new and improved capabilities. The next major milestone for VTOL X-Plane is scheduled for late 2015, when the four performers are required to submit preliminary designs. At that point, DARPA plans to review the designs to decide which to build as a technology demonstrator, with the goal of performing flight tests in the 2017-18 timeframe.

Universal Robots Add a Sense of Touch in New e-Series Cobots with Built-in Force/Torque Sensor and Re-Designed User Interface
With the new e-Series cobot line, Universal Robots raises the bar for cobots, adding unique new features while significantly strengthening the four core principles defining collaborative robots: fast set-up, easy programming, flexible deployment, and safe operation. With a new built-in, tool-centric Force/Torque sensor the e-Series is ready to take on applications requiring force control right out of the box. A repeatability of 30 micron means the new cobots are suitable for very precise finishing, assembly and electronics tasks. A re-designed user interface decreases cognitive load and expedites program development, while a new externally accessible, 500Hz system bus enables more complex motion control algorithms or profiles.
