AFWERX is finalizing its agenda, speakers, and panelists. If you have anyone in your network that would be a great speaker or panelist, please connect them with Evelyn Sabino. AFWERX’s goal is to connect innovators with as many government leaders as possible to help them make connections, learn how to work with the government, evaluate their technology, etc.

AFWERX brings together some of the top minds in industry, academia and the military to develop innovative, viable solutions to further strengthen the U.S. Air Force. 

See our presentation and apply to speak on Feb. 9.  

WiBotic was selected by the United States Air Force as one of 179 participating teams to compete in the AFWERX Challenge. The challenge is centered around six different categories, all designed to uncover opportunities to help the Department of Defense (DoD) become less reliant on fossil fuels, improve Air Force capabilities, and/or allow for more effective warfighting and humanitarian missions.

WiBotic is competing in the Energy Transmission and Distribution Challenge, which strives to identify ways to transport and distribute energy to where it is needed, and improve how the DoD consumes energy. Currently the DoD is the U.S. Government’s largest fossil fuel consumer and the single largest energy consumer globally. Its reliance on fossil fuels is both a paramount combat enabler, and a potentially crippling vulnerability.

Why WiBotic?

WiBotic’s wireless charging solutions greatly enhance the working efficiency of drones, robots and AUVs. As these vehicles become increasingly dependent on battery technology, and shift away from fossil fuels, the demand for autonomous wireless charging has intensified.

WiBotic’s specific benefits, applicable to both AFWERX and wider industry, include:

• Plug and Play interoperability between departments, agencies and allies. WiBotic’s onboard chargers are fully programmable and transmitter stations are universal, so diverse fleets can share a common charging infrastructure regardless of battery chemistry, voltage or charge current.    
• Decreased risk of system failure in harsh environments. With contact-based charging, physical electrical contacts must perfectly align, and be impervious to water, dirt, corrosion, and physical damage while being used repeatedly in difficult environmental conditions. Such contacts simply don’t exist today.
• WiBotic fleet energy management software allows remote visibility into an entire network of transmitters and onboard chargers, optimizing device uptime across the entire organization or battlefield.
• WiBotic technology lets autonomous devices charge themselves reliably, so robots can focus on their mission.

AFWERX brings together some of the top minds in industry, academia and the military to develop innovative, viable solutions to further strengthen the U.S. Air Force. We’re excited to compete in the program!

Today WiBotic joined the Advanced Robotics for Manufacturing (ARM) Institute. ARM’s mission is to work with its members to realize the promise of a robust manufacturing innovation ecosystem, by integrating institutional knowledge and a diverse collection of robotic industry best practices for both technology and workforce advancements. ARM focuses on disciplines that span the entire robotic ecosystem, from sensor technologies to software and artificial intelligence to quality control. Of course, battery charging is a critical component for all robot operations, and since WiBotic’s technology is at the leading edge of innovation in that area, we are perfectly positioned to help ARM members optimize power delivery to single robots or across entire fleets.

Our membership in ARM is particularly exciting, as WiBotic has an acute interest in supporting the American manufacturing sector. Domestic manufacturing and strong national defense are deeply interconnected, yet more than 63,000 U.S. factories have closed since 2001. This is a trend we’re committed to reversing.

We’re also excited about the workforce development aspects of ARM. Their funding of programs like apprenticeships and career pathways identify skills gaps in the manufacturing workforce and give students, job seekers and incumbent workers knowledge of and access to essential skills to continue technical training. These efforts provide a material benefit to industry directly, and by extension, enable us to foster the very best talent to grow our team.

We’re excited to join ARM and we look forward to partnering towards these shared objectives.

WiBotic has released a new version of firmware and the Control Panel software used to monitor and configure our wireless power hardware. This new version, Revision 13, makes the system easier to configure and use, and includes the following important new features:

• Common Names for Transmitters and Onboard Chargers: The feature improves the ability to monitor individual robots and transmitters by assigning them common names, such as “Aisle 4 TR”, “Pallet Robot 2”, or “Rosie” or “Optimus Prime” – whatever you’d like!
• Power Supply Mode – This feature configures the system to operate as a current-limited constant-voltage DC power supply for certain applications. It disables settings that are specific to battery charging, allowing for uninterrupted DC power output.  This feature is particularly useful for robots that already have an onboard battery charger or for applications that need a fixed voltage input and can benefit from the seamless operation of a wireless supply instead of a tethered or benchtop supply. Unlike benchtop power supplies, wireless power supplies require that the load current ramps up gradually, or the system will voltage limit. It is therefore important to consider how quickly the load consumes power when using this feature.
• High Temperature Charging: The new firmware also addresses a top safety concern for robot operators, safe battery charging at high ambient temperatures. New high-temperature charging safeguards keep the system from charging a battery if the OC senses the ambient temperature is greater than 45C – the maximum safe charging temperature for most Lithium battery chemistries. This feature can be disabled by the operator in situations where the OC is in a different location than the battery.

Additional “behind the scenes” improvements with the firmware include more rapid and reliable reading and writing of log files to the transmitter’s SD card; logging of additional metadata related to the charge cycle; and radio communication improvements between the transmitter and OC for better communications reliability.

Customers can take advantage of these updates today by navigating to the “Update” menu in the WiBotic Control Panel and clicking on the “Check for Updates” button. 

WiBotic is pleased to announce the availability of a CAN Bus communications link between our Onboard Chargers and NVIDIA’s newest processors for robotics applications.

NVIDIA® Jetson AGX Xavier™ sets a new bar for compute density, energy efficiency, and AI inferencing capabilities on edge devices, and Jetson Xavier™ NX brings supercomputer performance to the edge in a small form factor system-on-module (SOM). For this reason, Jetson has become an extremely popular platform for sensor-intensive robot navigation and control, synthesizing data and responding to environmental factors with blazing speed. 

When it comes to battery charging, though, most robot controllers just aren’t that smart. Blindly returning to the charging station when the battery runs low, robots simply accept whatever voltage and current the charging dock provides. This process happens over and over, cycle after cycle, with little regard for how charging is affecting the battery or the efficiency of the entire robot fleet. You could say it’s like eating the same food at every meal, for life. Boring, and not particularly healthy.

WiBotic changes that paradigm with intelligent wireless charging hardware and Fleet Energy Management software that charges batteries intelligently to maximize both battery life and robot fleet uptime. 

For instance, most chargers are hard-wired to reach 100% State of Charge (SOC) at the end of each cycle. They often do this by sending as much current as possible regardless of the battery’s age or condition. This type of “traditional” charging might be OK if the robot must return to service right away, but it’s a recipe for quickly degraded batteries and high battery replacement costs, especially where large fleets of robots are deployed.

In contrast, WiBotic’s intelligent chargers are designed to communicate directly with the robot controller to make better charging decisions.  For instance, if the robot naturally pauses during the workday, why not take those opportunities to find the nearest charger for a quick top-off? If you have all night to charge, why degrade the battery by blasting it with the maximum charge current? And if your robots are already operating all day on a single charge, why not experiment with an 80% or 90% max charge level? You’ll still complete the necessary work but may get hundreds more charge cycles from the same batteries.

With CAN Bus support built into NVIDIA® Jetson AGX Xavier™ and Xavier NX™, and a wide range of available carrier boards for simple hardware integration, we knew it would be easy to implement the above features – and it was! WiBotic also offers (ROS) drivers and a powerful Onboard API to make the integration process even simpler. 

In short, once communication between Xavier and the WiBotic Onboard Charger is established, operators can finally make intelligent charging decisions to maximize productivity from each robot. Apply these capabilities across a fleet of 10s or 100s of robots and now you’re talking real Fleet Energy Management!
