Re: Make a more powerful but still tiny drone.

I dont have issues with the ToF sensors. They are not influenced by the propellers. My next topic is how can the bolt fly inside a room in about 1,5m height starting from ground and then crossing tables and other obstacles without jumping up because of height measurement from the flow deck. How can ...

Re: Crazyflie Bolt issue with motors

This can also happen if the esc is not initialised. On normal quads if you have a new esc you can initialise it with the joystick of your transmitter so it knows what is 0 and 100%. So the question is how can you initialise the esc via bitcraze software.

Re: Make a more powerful but still tiny drone.

Thank you Tobias your hint was perfect! After correcting the vzkp and vzki values everything is working fine now. A little fine tuning of PID values is still open and having a look at the landing behaviour. How can I post a Video?

Re: Make a more powerful but still tiny drone.

Thank you Tobias, I will test this tomorrow. Do I have to tune anything in the PM_BAT_DIVIDER for 2s? #define PM_BAT_DIVIDER 3.0 f #define PM_BAT_ADC_FOR_3_VOLT (int32_t)((( 3.0 f / PM_BAT_DIVIDER) / 2.8 f) * 4096) #define PM_BAT_ADC_FOR_1p2_VOLT (int32_t)(((1.2f / PM_BAT_DIVIDER) / 2.8f) * 4096) or...

Re: Make a more powerful but still tiny drone.

Thank you Tobias for your reply. I will change the weight for the bolt in the estimator_kalman.c and make a test. Is the LED ring script also adressing the heart beat led which is onboard because this is the led I want to use for bat monitoring. I cannot add another board when I have the multiranger...

Re: Make a more powerful but still tiny drone.

Thank you for sharing your values!! :D Flying with joysticks is o.k. now. I lowered the slew rate, lowered the base thrust and tuned the rate pid. With the sticks I also get a smooth take off but when pressing the button for assisted mode ( hight hold/ position mode) the Bolt shoots up in the air. W...

Re: Make a more powerful but still tiny drone.

During my test I was in position mode. Is ist necessary to have the flow deck right under the bolt board for holding the position? I put it to the back of my frame to have space for the battery in the center of the quad. Can this be the reason for the backward drift?

Re: Make a more powerful but still tiny drone.

I managed the pid tuning, flashed the firmware and with a game controller and the cfclient the bolt flies well. On board I have the flow and the multiranger deck and I tried out the multiranger_push script from the examples folder. Take off is o.k, when hovering there is a backward drift and with th...

Re: Make a more powerful but still tiny drone.

@leonana69
may you share your pid and thrust base values so I can compare to the crazyflie and make the right decision for my new quad?

Re: Make a more powerful but still tiny drone.

Do you have a kind of manual for tuning the parameters for the bolt? Do I find all relevant parameters in the parameter list of the cfclient?
