I want to make a precision laser scanner for topography applications. I would like to know how to determine the angle of each measurement very precisely so as to obtain the X, Y, Z coordinates. What sensor and hardware you need.??

This problem has two parts: Which laser scanner (accuracy, resolution, maximum distance, etc.) How to know the angle with reference to the ground. For the first issue, you could browse our LIDAR category here . A good option may be the RB-Mrp-01 . It has a range of 150 m, an acc…

Hello scharette … Thank you very much for your prompt response. I have doubts that the number to refence better. For the telemetry sensor I’m going to get it for Garmin Lidar lite v3 - RB-Pli-06. (For its precision, besides that I have a new one) 1.-For the accelerometer It d…

Hi, A device such as the RB-Phi-166 is meant to be used by a USB host (such as a computer, laptop, or even a Raspberry Pi). The Arduino Mega 2560 may be able to use it with a USB host shield, but that requires special device drivers (which may or may not be easily found). As fo…

Good morning Sebastien … Based on your observations, I will have to opt for another sensor, open some that you can recommend that is compatible with the Arduino Mega 2560 pins and high precision, there are several and I do not know which to select. I have a MPU-6050, although i…

The MPU-6050 (we have a breakout board for it here ) should do fine for prototyping / proof-of-concept. Just make sure to change its range of acceleration to ±2 G. Once your device is stable, you will get a good reading on the gravity (1 G). As for conversions, there are many ex…

Hello scharette … I’m absent but I’m back… I’m reliving this project… make a scheme of the prototype that I would like you to see and give me your opinion. [IMG_20190227_163306] Looking at this image, I have the following doubts. 1.- if we place an engine with an encoder i…

Welcome back (and to our new community site, too!!!)! Better late than never, as they say! :slight_smile: [image] gustavo_mvj: 1.- if we place an engine with an encoder instead of the MPU. which of the two cases will give me more angular precision.?? As oppose to an acc…

Hello Scharette… thank you very much for your prompt response. at the moment I will use the motor steps because of the cost. 1.- What do I need to check to choose a motor with good precision steps? (her CARACTERISTICS) 2.- Stepper motor has good rotation speed for faster scan…

[image] gustavo_mvj: 1.- What do I need to check to choose a motor with good precision steps? (her CARACTERISTICS) One of the most important characteristics when it comes to motors is torque. If your motor cannot do the work required then it will simply not work. As a goo…
