Questions tagged [quad-copter]

This should be used when asking any question about quadcopters.

Also called Quadrotor Helicopter, a Quadcopter is a helicopter that is propelled by four rotors. Typically, two of the rotors are set two clockwise and two counter clockwise. By the variation of the RPM of these rotors, torque, thrust and lift are controlled.

How would you dampen this little quadcopter?

Well, I made a little quad from scratch. From scratch as in from PCB design. After assembling, testing, some coding, it turns out my accelerometers get WAY TOO MUCH vibrations and I can't detect orientation using Kalman filter... Bump! Has anyone…

4 channel software PWM using Atmega16 for controlling 4 ESCs for brushless DC motors

I am trying to implement software implemented PWM for controlling 4 ESCs using an atmega 16 microcontroller. To achieve that I am sequentially generating the pulses for each ESC one by one in every period of the signal. Here's the code - #define…

PID controller slowly oscillates out of control

I am trying to tune PID controllers for my drone. There are 3 controllers, one each for Pitch, Yaw and Roll. I have gotten Yaw tuned to a reasonable amount and I am assuming the values for Kp, Ki and Kd are pretty much the same for pitch and…

MPU-6050 angle readings under mechanical vibrations

I'm in process of making a quadcopter. At this point I encountered a problem with MPU-6050 angle calculation. When quadcopter is stationary with motors in off state and I'm tilting it, angle readings in all 3 axis is good, but when motors are in on…

Quad copter - from PID values to motor power

I am struggling with a completely self built/written quad copter I am working on. I am working on the PID controller for balance, right now just with a P value and it only reacts on ROLL and PITCH to minimize potential errors. I put the prototype…

Is it normal for a transistor running a motor to be very hot?

I've researched for a few hours but I'm still concerned. I'm building a very low budget quadcopter (think toothpicks) and as I've seen on this site, a D10N05 mosfet would do the job. I've visited 3 of the largest electronics shops in my area but…

How to run ATmega328P-PU using 3.7v Lipo 600mAh?

I want to run bare ATmega328P-PU using 3.7v 600mAh Lipo Battery. The Lipo is used to run Nano Quadcopter. The discharge rate is 20C. My Question is: 1. Will connecting Lipo to my atmega directly fry up my chip? 2. Do I need any Voltage regulator?

How to prevent a battery powered microcontroller(ESP32) from reseting when motors start running?

I am working on a brushed motor quadcopter. It is powered by a 3.7V LiPo Battery. I have an ESP32 microcontroller which sends PPM signal to a SP Racing F3 EVO Brushed flight controller. The 3.3V to the ESP32 are provided by a LDO…

Can you discharge a 3s LiPo battery from both its main plug and it’s balance plug?

So I’m building a quadcopter, and I want to be able to use the same battery to power both the escs and the flight controller. However, the escs are connected to the PDB which is connected to the main plug of the lipo. I was wondering if it was safe…
