most comprehensible and shortest hexapod diy video on whole youtube, thank you please keep going!

Nice to see that new hexapods are being built every month!

Beautifully done - I'm liking the design simplicity, it feels achievable. Seeing hexapods was what got me into Arduino, and it's a bucket list project for me. Currently losing my mind on the design/build stage of a Rubik cube solver. Next project is a pen plotter, and then perhaps the hexapod (if I'm still sane by that time 😆) Great video production quality by the way!

what software do you use to create the 3d model? and are the servos in the software accurate dimensions?

Thank you for sharing. Where can I download the print file?

Great project, but I have a couple of questions: I've printed and assembled the robot. I've tested the individual servos and they all work. Numbering the servos clockwise from 1 to 6 (bottom view), I wired them to the starting at pin 0 in the order coxa, femur, tibia. I uploaded the hexapod.ino code, making sure the pin offset is 0. When I start it, all that happens is all the legs close up and then it just sits there for 16 seconds, then does that again. I thought there was an issue with the LiPo battery feeding the Arduino, so I attached a 9V battery and removed the yellow power jumper from the sensor shield. That worked a little better in that the legs were trying to do a cyclical motion, but they were still very closed up. I'm thinking either the legs are wired incorrectly, or I assembled the legs at the wrong servo angle. I set all the servos to the zero position before assembling, and assembled the legs fully extended as in Step 3 (so that the two screws as shown are parallel to the servo body. Thoughts?

Thanks for trying out the project :). Based on what you're describing, it sounds like the femur angle might be off by 90 degrees - might be a mistake in the vid/tutorial. Could you try changing J2_OFFSET from 0 to -90 in the code and let me know what happens? Looking forward to hearing how it goes!

@@zeroshotrobots Thanks for the advice! I actually ended up setting all three offsets to 0. I also found that the servo at pin 0 was not firing, so I moved them all up to use pins 4-21. I'll post a video soon.
