Dont stop posting bro, I see your potential. Never give up. It is insane to me that this only has 1.6k views, it should have at least half a mil. Keep up the good work!
For a future upgrade, you should try machine learning for the legs with a 360 camera in the middle (on top) as input. Maybe when TH-cam finally blesses this channel with a huge amount of views...
I wanna do many upgrades, but I need to get the mechanics and electronics working before I go for software and more advanced stuff. I am gonna do some by the end of this summer hopefully.
What is the power rating of the batteries you're using, and which DC-DC converter did you use? I'm building a hexapod with motors of the same 25 kgf brand, but I'm experiencing power supply issues. For some reason, the servo motors get lost when moved simultaneously, and some start moving slowly.
I am using a 2S lipo battery, which directly powers the servos. The servos are rated for 6.8 V, but I haven't noticed any problems even when I power them with the full 8.2 V from the 2S lipo. I had the same issue you described when I was using a breadboard and a 15 A DC/DC converter, which wasn't providing enough current.
@@TazerEngineering Thank you very much for your help! Indeed, the problem was solved by using an external 50A power supply. I will also buy the batteries as suggested. I really appreciate the tip!
@@conorstewart2214 Yes, that's correct: "25Kgf" is the torque. However, I was able to identify the manufacturer's brand of the servo motor shown in the video, and it is the same brand that I use, but a slightly more powerful model.
Another question: how do you synchronize the movement of the hexapod's legs? I’ve noticed that they start moving at different times, even without any programmed delay between them. I need legs 1 and 3 to move simultaneously in the same direction, but I see there’s a delay in the start of one of them. Did you do anything to resolve this issue, or did your hexapod not exhibit this behavior? Thank you in advance for any tips.
The code has 3 vectors of x, y, and z coordinates, which trace the leg trajectory. The vectors are pre-programmed and have 100 elements each. The code has a for loop which goes from 0 to 99. Each iteration I set 3 legs to x[i], y[i] and z[i] and the other legs are offset by 50. I used the modulo function for the offset.
@@TazerEngineering I employed a similar approach to move the three legs simultaneously, but I observed that they do not remain fully synchronized. Additionally, I chose to develop a pre-programmed movement vector, although I used only 10 elements. What concerns me is the movement of these three legs; I feel that even though they are moved to the same position, they end up arriving at different times, which could potentially affect the forward movement of the hexapod.
@@guilhermeconstantinov You probably need more elements. If the leg moved in a straight line and you used only 2 elements, the position would be accurate at those 2 points, but the movement in between them would be unexpected because each servo reaches its target angle at a different time.
I discovered that the problem was related to the excess use of Serial.print commands in my code. These commands were delaying some steps and reducing the motors' speed. After removing them, the motors resumed operating in sync. Additionally, I decided to add more elements to the list to smooth out the movements, as per your suggestion.
1:51 this is an issue with your printer, i calibrated mine and if i have a 50mm id, 65mm od bearing, i make my model with those exact values and its a perfect fit everytime

i like this little guy(robot)!
hope to see more!
2:58 i think there's a formula for calculating how much u need of a specific substance in order to get the right percentage
why I have the feeling that the one who'stalking is the robot ? :D good video !

Did you remove some of your vids?
@@SageBlueMusic No, my hexapod videos are on youtube shorts tho.
no way u dont have 2m subs i dont understand

"25 kgf" is not the brand but the stall torque. They look like generic servos.

Does it work for different nozzle sizes? Mine expands more with bigger nozzles and I change them all the time.
which microcontroller are you using ? Can you please give some info about your control system.
The microcontroller is Arduino Mega and I am not using any control system(apart from the PID in servos).
