mro (8)

Because the DIY community asked for it. Here’s the new mRo Pixracer Pro with tons of functionalities.

4 years after the original mRo Pixracer was designed and proven mRobotics recognized the need to bring the design to the forefront of open source flight controllers.

With the mRo Pixracer Pro mRobotics maintained everything that the community loved about the original mRo Pixracer and improved every deficiency that was known. The resulting fight controller is destined to become the new goto flight controller for developers and a rock solid foundation for commercial and industrial systems.

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.

mRo Control Zero A High-End Nano Autopilot

5334384296?profile=original

mRo Control Zero F7 a High-End Nano Autopilot...

The smallest and most powerful autopilot in the world of its kind created for a high-end unmanned vehicle builders!

mRo Control Zero, at its core, is a universal development board and is fully compatible with Ardupilot and soon PX4.

We have designed the mRo Control Zero in such a way so that it is highly customizable and adapts to industrial needs that are required, our new autopilot includes all libraries and examples that allow initializing and accessing all the sensors and functions of the board directly through our reference code and another very important thing, the manufacturing process is completely different from the conventional one which makes it much safer and more efficient.

Main Features:

- Main Processor STM32F777

- Crypto / Hash Processor

- Bosch BMI088

- High-perfomance IMU

- Internal Vibration Dampening

- Electromagnetic Shielding

- Corrosion Protection

- Two Ease Main Connectors

- Weight: .19 oz. (5 g)

- Width: .79” in (20mm)

- Lenght: 1.26” in (32mm)

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.

This is how you can learn at a glance the technical characteristics of the mRobotics family of autopilots and decide which device best suits your projects.

The mRo autopilots are designed and manufactured to create the wide variety of platforms that the industry requires in different ways. They are designed to provide reliability for the quality of the components used and manufacturing process, versatility in their physical and logical interfaces and in some cases to offer logical security by encrypting the information processed by the autopilot itself.

You can build custom cables yourself or with mRo help to optimize weight and space. It can easily adapt them to carrier boards to interconnect other devices in one piece.
