Mateusz Sadowski commented on Felix Meissner's blog post New Project: Implementing Autopilot Control in a Hybrid 4WD RC Mulcher
"Keep us posted!I was looking a bit on something similar. I think a lot comes down to your end goals. For a simple control ArduRover can work very well, you will be able to do coverage planing etc. with the ground control station software. If you…"

Mateusz Sadowski commented on Dmitry Skotnikov's blog post Your In-Flight Wireless Charging Solution for Drones
"Interesting! What kind of battery are you using on the quad? Are there any side effects of charging a 22Ah battery at 150A?"

Mateusz Sadowski commented on Patrick Poirier's blog post Autonomous Flying using the RealSense T265 Tracking Camera in GPS Denied Environment
"Also @Patrick: when you copied the lab description by mistake you also copied the number of clicks, making it a bit confusing about "ROS 2" based labs (I got quite excited for a second!)"

Mateusz Sadowski commented on Patrick Poirier's blog post Autonomous Flying using the RealSense T265 Tracking Camera in GPS Denied Environment
"WOW! Great job! I strongly believe that combining ROS and ArduPilot can result in really powerful applications. Are there any plans to host those tutorials outside of ArduPilot forums? I'll be sharing the information about the labs in the next issue…"

Mateusz Sadowski commented on Mateusz Sadowski's blog post YDLIDAR X2 - $69 LiDAR review
"The scan frequency is ~7Hz therefore we can assume that LiDAR needs to rotate once to collect a single scan. This means that the rotations speed is 7RPS * 60 = 420 RPM

Also if we are collecting 3000 samples per second and the LiDAR does 7 rotations…"

Mateusz Sadowski commented on Mateusz Sadowski's blog post YDLIDAR X2 - $69 LiDAR review
"You would install it on a real car or an R/C one? If it's a proper car then I suggest you don't use this LiDAR, it's a maker quality tool not suitable for safety applications.
If my calculations are correct you should get about between 400-500…"

Mateusz Sadowski commented on Mateusz Sadowski's blog post YDLIDAR X2 - $69 LiDAR review
"Chris I tried to find any YDLIDAR python libraries but apart from the one linked by Stefan I couldn't locate any.  The PyLidar3 doesn't seem to support YDLIDAR X2 just yet.

The oficial SDK for YDLIDAR seem to be this one and it's written in C++."

Hi guys! I recently had a chance to test out YDLIDAR X2, that could be a cheaper alternative to RPLIDAR. Here are some of the characteristics of this unit:ParameterValueScanning range360°Range0.1-8mRange resolution2% of distanceScan…

Mateusz Sadowski replied to xemone's discussion Maximum number of Lidar for Object Avoidance in ArduCopter User Group
"It's been a while since I've been working on Object Avoidance with ArduCopter. I only worked with TeraRanger Tower (https://github.com/ArduPilot/ardupilot/blob/fb544cab78efe05e74b368c...).

Looking at the update_sector_data function you can see that…"

Mateusz Sadowski commented on Chris Anderson's blog post Why anti-poaching drones haven't worked well
"Thanks for the great insights Chris! Although the forum is not the format I would usually link to at WeeklyRobotics the discussion is so eye opening that I'll most probably make an exception."

Hi guys! Recently I had a chance to experiment with Livox Mid-40 - a 230 m range LiDAR using rotational Risley Prisms.I thought I would share my findings with the community in case it can be considered a viable scanning solution!The first thing to…
