Hi everyone, I am from South Africa and this is my micro servo humanoid that I am currently constructing. So far I have spent about 4 days on it, still a lot to be done.
The reason I am using micro servos is because of their low cost (about $3 each). I was initially concerned that they would not be up to the task of handling the weight of the robot while walking, they are at their limit, but the robot is able to walk.
Materials:
- Hard board
- Plywood
- Aluminium extrusions cut and bent to size
All of they above materials were purchased at my local hardware store, so no fancy 3d printers or any such devices where invloved (though I do hope to get one one of these days) :)
Electroincs:
- Arduino Mega
- 14 x Micro Servos (1,3 kg/cm)
- HC-SR04 Ultrasonic sensor
- 4 x AA 2700mah cells
Planned features:
- Walking (Mostly complete)
- Push ups(Mostly complete)
- Obstacle avoidance
- Voice recogniton (To be added later with a small Android phone)
- Face recogniton (To be added later with a small Android phone)
Some pictures:
I will be uploading a video soon with its first walking gait, and will be keeping this page updated with my progress.
Thank you! It is indeed quite a squeeze to get everything in. However your bots are smarter and more mobile (this little dude walks super slowly, wheels are far more practical)
Neat robot! I am running into the same problem, servos too weak to carry the weight. Am thinking of moving to 7.4 volt servos - lots more torque and can use lipo battery.
Would also like to see video of it walking and be interested in seeing your code.
Very nice project! 9g servos are great because they are inexpensive and small, but normally consume high current and don’t provide great torque. Wire wrapping will certainly help with the aesthetics. Looking forward to seeing you add more info.
Thanks! I would have liked to use some high torque 6v servos with a few BEC’s to drop the voltage from a 7.4v lipo but that will be a project for another day and another budget. Will be adding my code once it’s finished
Thanks man! I will be making a video soon, thanks to my cat bumping the robot off a table some of the servos have been damaged so I will first have to get some new ones this weekend
