My Hexapod Robot Build
After building two linear delta 3D printers and numerous flying drones, I figured it was time I tried my hand at building a six legged remote controlled robot, otherwise known as a hexapod robot, or simply a Hexapod.
I looked at various designs on the internet and eventually decided on this one, which uses a 3D printed frame, inexpensive servo motors, and an Arduino Mega 2560 for the brains.
The great thing about this Hexapod is the low cost because you 3D print the frame yourself and the servos are less than $5 each. This hexapod is based on the Trossen Robotics PhantomX hexapod, which costs about $1200. This home made version comes in at less than $250, which is more than an 80% cost saving compared to the real thing. The best thing is that it works about as well as the more expensive version.
Another reason I chose this one is that it uses an Arduino Mega, and there are plenty of other hexapods out there that use the Mega, so there was the possibility of using different software or even upgrading to more advanced software, such as this hexapod that uses a Pixy AI camera to track and respond to objects.
The parts files for 3D printing the frame can be found at Thingiverse.
You can also see my detailed build notes on Thingiverse.
Overall the build was very successful once I did some initial troubleshooting of some minor mistakes I'd made during the build.
Here is my video of the Hexapod's different movement modes. Be aware that those are 1ft x 1ft (30cm x 30cm)tiles, so this thing is pretty big, a couple of feet across.
