This is a renewed high-quality power module standard based on the ACSP7 but with dual internal power supply to improve the stability of the hall-sensing.

The mRo Power Zero from mRobotics is designed especially for the DIY community and it offers extremely accurate measurements across the entire current & voltage operating range with a non-invasive Hall-effect current sensor for UAV / Robotics application and high precision voltage dividing circuit for consistent and reliable measurements.

Compared to the ACSP7, the .5v offset is removed and the current sensing is compared with a dedicated power reference. The integrated electrolytic capacitor reduces voltage spikes which result from longer input cable lengths and higher voltage batteries.

At mRobotics our commitment continues with the entire research, development and integration community and we want to announce that we are making several alliances with interesting companies for the UAV sector and as always to offer you hardware for integration, ready-to-use products and solutions.

I want to share the press release that was made through sUASNews

FlytBase, Inc. and Mayan Robotics, LLC have announced a partnership to support enterprises on the development of fully autonomous, cost-effective drone automation solutions that leverage open source technologies.

As their drone operations move from manual to fully autonomous, businesses are looking for reliable, cost-effective, scalable hardware and software components that can seamlessly integrate into enterprise-grade solutions. The commercial drone industry is driven by regulatory progress and technology advancements – both of which are picking up pace as industries, governments and consumers all start to derive meaningful value from unmanned aerial vehicles.

FlytBase, Inc. provides drone agnostic software solutions to automate and scale drone operations. The FlytBase technology platform allows easy deployment of intelligent drone fleets, connected with cloud-based business applications. FlytBase offerings are compatible with major drone hardware platforms (eg. DJI, Ardupilot, PX4) and come with SDKs, simulator and APIs for reliable testing and seamless integration. FlytBase customers range from sectors such as public safety and energy utilities to warehouses, distribution centres, and air cargo facilities.

Mayan Robotics LLC specializes in the design and manufacture of essential electronic systems for unmanned vehicles, drones, and UAVs. With a focus on the best known open source and open hardware-based autopilots in the world, Mayan Robotics’ products are utilized by the largest civilian drone manufacturers, public and private aerospace research and development institutes and militaries across the globe.

As US-based companies, both FlytBase and Mayan Robotics are excited about the rapid progress made by regulators on enabling drone flights at night, over crowds and beyond the visual line of sight (BVLOS). With the ongoing FAA-approved integrated pilot programs, the commercial drone industry is poised to accelerate, driven by fully autonomous solutions that focus on specific use-cases in each sector. These range from outdoor solutions such as aerial inspections of oil & gas pipelines and wind turbines to indoor applications such as warehouse inventory management and mining.

The first step towards enterprise drone applications was manually flown UAVs by drone operators and service providers. This has now matured to live drone operations, where a fleet of drones can be remotely managed, with live video feeds available over 4G/5G, and the ability to not only fly drones autonomously but also control the camera gimbal, set waypoints and geofences, share and archive image/video data on the cloud. With the availability of off-the-shelf, cost-effective drones, enterprises can now build a fleet with a minimal upfront investment and rapidly realize business value from aerial inspections, surveys, mapping, surveillance, search-and-rescue ops, etc.

FlytBase & Mayan Robotics, together, seek to enable cost-effective commercial drone adoption not only by large corporations but by SMEs, drone operators and sector-specific UAV system integrators as well.

Jordi Muñoz, Mayan Robotics Founder, commented “We have strategically located our headquarters in San Diego California, in addition to being the only manufacturer of our kind that designs, manufacturers with globally sourced components, assembles and ships all products from the United States. This allows us to ensure the safety, reliability, and quality that enterprise customers expect from drone hardware. By partnering with FlytBase, whose intelligent automation software perfectly complements our offerings, we can now provide end-to-end drone solutions to drone developers, system integrators, and of course the end-users.”

According to Nitin Gupta, FlytBase CEO, “The partnership with mRobotics is designed to help our customers leverage best-in-class, open-source hardware, and software for building enterprise drone automation solutions. As fleets with dozens of autonomous drones get deployed across industrial use-cases, the focus will shift from purely technology to reliability, scalability, and operational integration. We see enterprise drone adoption rapidly moving from proof-of-concept projects and pilot programs to true production deployments – and look forward to this partnership as a means to enable commercial drone automation, at scale.”

At mRobotics our commitment continues with the DIY community. From San Diego California we design and manufacture the necessary hardware to build platforms and solutions based on Ardupilot and PX4. And now we show you the next high-tech GPS that has build-in CAN, which includes many and special improvements to achieve maximum accuracy in positioning and guidance for safe navigation.

One of them is that we have incorporated the RM3100, a new Geomagnetic Sensor. Like a pair of glasses, the RM3100 Geomagnetic Sensor enables you to see magnetic fields clearly. 

The RM3100 Geomagnetic Sensor is the highest performance sensor in its class with over 10 times better resolution and over 20 times lower noise than the leading Hall Effect sensor. It makes precise magnetic field measurements, which enables accurate calculation of heading and orientation. The earth’s magnetic field provides absolute reference for heading measurements and accurate motion tracking. Geomagnetic sensors are used to measure the earth’s magnetic field; however, in real world conditions, the earth’s magnetic field is often distorted by other surrounding fields. System components such as batteries, shielding materials, or motors will distort the geomagnetic field near the sensors. An additional design challenge is the changing magnetic environment that temporarily distorts the field like metal parts in furniture, a passing car, or nearby cell phones and computers. Geomagnetic sensors must first be able to see the different magnetic fields in order for the designer to separate earth’s magnetic fields and compensate for the distortions. PNI Sensor’s RM3100 eliminates any “blur” in your magnetic field measurements making distortion error correction a snap, and ultimately allowing you to easily and accurately calculate absolute orientation and heading of a drone or vehicle.

I share a little information that Jordi Muñoz comments about the new "mRo Location One GPS" that we are coming soon to launch.

For more information or questions please feel free to write me directly at help@mrobotics.io just mention me in the mail body ;) or follow us on our social networks at www.mrobotics.io

"Can you see the PCBs that are side by side? Can you spot the differences?

The one on the right is an early prototype, it has a lot of holes(vías) to "clamp" the ground plane. The one on the left is clean! Why? Well, we are experimenting (sorry for keeping all the engineering fun). The left one is a new concept that uses blind vías which are drilled by laser on the inner layers (4 in total). This allows us to have a very clean ground plane, which leaves the cooper of the first layer free of "artifacts", and the ground is attached around the antenna pin -The ground plane shape and dimension is a fundamental component of the patch antenna-, the idea is to create a more predictable behavior.
This new GPS is known as mRo Location One and has build-in CAN. It also has the new RM3100 compass, the only one currently working and supported by Ardupilot (via CAN), this mag has extreme performance and we salivate every time we fly with it. We also added a "bump" to all of our GPSs, the bump is the little piece of land on the front where the magneto resides, an attempt to keep it away from all disturbances and boost performance.
This module is ready for mass production and it will be released with the new uBlox M9N, which has true multiconstallation support and higher refresh rate.

Landing with strong wind using mRo x2.1-777

During some tests that we carried out autonomously of the mRo navigation systems, while we flew, the wind began to blow very hard and we decided to suspend the mission and land manually because the wind was increasing more and more and the gusts were erratic and unexpected.

To end the day, during the final approach the pilot made some low passes to be able to take some pictures of the plane from very close. Once the photos we achieved and we saw the circumstances complicated by the wind and the difficult landing, as fun we challenge the pilot to land with aim.

Due to the strong wind we couldn't land at the first attempt, so we had to abort the landing on several occasions repeating the same flight pattern.

At some moments during the final approach phase, we switch to “Stabilized” flight mode to check the safety that the mRo autopilot (mRo x2.1-777) brings while corrects the plane banking very quickly.

The video quality is not at all the best, because vibrations are shown on the camera and this is because it is mounted on a pan/tilt system.

mRo Control Zero Autopilot for Unmanned Vehicles

3689741948?profile=original

mRo Control Zero Autopilot -- made in USA

The smallest and most powerful autopilot in the world of its kind created for unmanned vehicle builders made in USA!

A high-performance autopilot, specially designed for advanced/professional users who require the best of the best with minimal space.

3689742422?profile=original

Built for Builders!

"mRo Control Zero", in its core, is a universal development board and comes fully supported by PX4 and Ardupilot. If you require further customization, the mRo Control Zero will come with all the libraries and examples that will allow you to initialize and access all the board sensors and functions directly via our reference code.

Yes, you will be able to create your custom software for this board in no time, no need to worry about initializing everything (We did it for you). The software is written in C and utilizes a free, easy to install Eclipse-based IDE and supplied by ST. All is included for free with the sole purpose of giving you access to learn, edit, and improve. Be sure to read and understand ST Hardware Abstraction Layer (HAL) license.

But… Be aware of the “limitations” of C, any careless handling of a single byte can potentially provoke a buffer overflow (don’t worry, it won’t damage the board). But hey, This how we all learned at some point, right? The recommended IDE also supports C++ so that you can jump to objects anytime you wish to.


You are Covered!

The mRo Control Zero comes heavily shielded from EMI and highly static hands, so feel free to use your grandma’s polyester sweater while handling the board. Many cloned autopilots come with some potential design flaws that if are manipulated improperly it will permanently damage the board. We know you might have burned one (or two)!

The mRo Control Zero has multiple, independent power supplies, internal voltage sensing, EMI shielding, resettable fuses and buffered PWMs.

The PWM outputs are level shifted to 5V for optimal noise reduction and compatibility across all consumer and commercial ESC devices. With a total of 8 output channels, each with DMA support for 8x dShot devices (yeap, they are all Bi-directional). Every pin exposed is protected.

The PCB is a 6-layer stack with an optimized concentration of copper that ensures excellent heat dissipation, but the F7 and H7 microcontrollers are more power efficient and therefore they dissipate less heat compared to the all F4 microcontrollers.

Lastly, the mRo Control Zero has a conformal coat to protect it from the environment. Conformal coating is an acrylic layer that covers most the electronic “pads” — leaving exposed only the sensors that require direct atmospheric contact, like the pressure sensor and the buzzer.
