Exactly how are the 2 servos for the hip assembled, you left that out. I assembled them as closely as I could from looking at the image, but they are not completely stable, the two servos in their separate mounts when put together have some wobble. Never mind, I figured it out, but you might want to fully assemble the hips when you first build them. You don't show that.
Cool kit. I got it walking, still needs better calibration but it's crawling. I had a servo go all twitchy on me so I ordered some replacement servos. Works great on a Pi 4. Sonar sensor works, Camera works, buzzer works, only thing that does not work is the LED array, but I only started tinkering with it, also the bad servo. Tinkering with it is half the fun though. Good kit, I don't recommend for beginners but a determined and patient beginner could get this done in an evening or two.
For pushing the servos into the spline connectors, use a cheap pistol grip ratchet jaw clamp. They wont damage the components and it makes the first time marriage of the components so much easier. I just happened to have some laying about from other DIY projects; saved struggling to squeeze things together.
why do my servos not work when I type in test.py servos and im a first year comp sci student. one has tried everything. leads me to think its a faulty part or something
The assembly process has been very fun and challenging. Until... I get to the head. The screws that give support to he picamera and the ultrasonic module have poor quality and both modules wobble. I had to use ducktape to keep them in place until I find a long term solution. The product is excellent but the head screws were so much disappointing.
@@iAmMikeHill Please make sure the standoffs are not tilted and try to tighten them again. If the issue remains, please email our support team at support@freenove.com.
Check the Battery Type: First, ensure you are using the correct type of battery recommended for the kit. Using the wrong type can lead to insufficient power supply. Proper Charging: Make sure the batteries are properly charged. If you're using rechargeable batteries, follow the manufacturer's instructions for charging. Some batteries have specific charging requirements, and not following these can lead to undercharging or damage. Power Distribution: The Raspberry Pi requires a stable power supply to function correctly. If the power from the batteries is fluctuating or too low, it can result in dim lights or failure to power up properly.
Can you pls clear my doubt in between when you are assembling the servi motor to the main board corners how the design replaced?? I am confused which part you used
Hi I have a question and hope I can get the answer here. I put together everything and connected the server. Now my hexapod keeps beeping, and it seems that the load button light is blinking, and the servos are not responding at all. What could be the root causes? I tried everything and I could not fix it.
My servos don’t seem to work when I type the code, even though everything else works. I tested the writing again and everything looks fine. Do you know what I did?
Hello good afternoon, I bought this robot a long time ago, I bought it with my Raspberry Pi 3 operated because the P3 broke, I decided on a 4, now unfortunately it is like that I have the complete tutorial several times from front to back processed from the software installation and unfortunately it no longer works I can unfortunately not find the error I hope you can possibly help me since I've been using the berry Pi 4 robots can no longer be used
@@mausambahar8111 Sorry, there is no i2c interface left and the servos have already consumed a large current, so it may not supply enough power if you connect more PCA9685.

Hi! You only need to put in the batteries according to the positive and negative marked on the board. Please note that only flat-top batteries are compatible.
I had trouble with Servo.py. What's wrong? ..... PCA9685.py", line 36, in write self.bus.write_byte_data(self.address, reg, value) OSError: [Errno 121] Remote I/O error
49:38 OMG, I wasted so much time for trying to solve my camera issue when it was only loose... Btw screwed up all my configs as i tried to fix this in the software. Please put this to the tutorial so you can save much time of people and prevent the stress it causes.
@@Freenove I thought the video was pretty great! I have really enjoyed the video. I prefer using both but the video was good and y'all did a great job putting together. Much appreciated
This was a very helpful video. Thank you for providing it! It/s best if you take your time, use the video with the tutorial /docs, pausing the video along the assembly process
@@Freenove I used a sliver of electrical tape about 5mm wide to hold the nut in place, then assembled the parts. worked well. So far I really like the project.
I have to admit, this was a pig of a part to get right. I managed to develop a technique of pushing the smallest digit on my left hand into the gap and resting the nut there and sort of hoping the thing would stay in place when the bolt was slid in and screwed down. It worked by sheer luck I think ;-)
@@SimonDaviesCyclist Doesn't sound like luck to me....sounds like a lot of experience at some time with fiddly parts. I did the same although months after you. I like this robot, trying to build it with my kids. Got a bit stuck with the raspberry pi 4 around the vncserver now needing to be enabled on the pi, but back in business now attaching the legs. Awesome to have the capability to control 20 motors remotely with video streaming.
Why do your PDF instructions not include a over half of this please I want a detailed explanation of why your PDF instructions do not have these steps included in them how is a kid supposed to get this figured out by themselves. And why is this just a video of someone plugging in wires instead of actually providing the instructions of which motor goes to which port seriously this is pathetic
How is a kid supposed to be understood coherently when they won't learn how to write correctly? If you had bothered to pay attention, you would've noticed that, while the PDF is lacking a lot with some steps, in the video they say where to plug in the head servos. I assume you meant the head servos since the PDF does, in fact, tell you which pins to plug the leg servos into. If you had your board oriented the same way it was in the video, you'd notice that they were plugging the head servos onto the Servo0 and Servo1 pins on the lower left. The board DOES say "Servo" followed by the associated numbers in white-outlined boxes. If anyone is pathetic, it's you for not paying attention.

Hi! Many thanks for your comment.
I can confirm that the Raspberry Pi Zero 2 W is a perfect replacement drop in for a standard Pi. Seems to be working so far!
Thank you for your feedback. Great work.
(You need to get the cable for the camera as an extra, but that's it, no other hoops to jump through)
@@SimonDaviesCyclist Thank you.
The stand nuts and hardware loosen themselves very quickly, be sure to buy some thread locker to keep them tight.

once assembled can you record a set of actions and have it repeat them?

Should be simple enough to code for that, a record and layback function. I will have a pop at it when i complete the build it wont be immidiate.
