Tachikoma by TheMaverick

[TheMaverick]

Hi Everyone,
this is my first post here. I Want to show you my current Tachikoma Projekt.
Since March 2020 i am designing the Body parts for a large Tachikoma.
From front left Leg to rear right Leg it will have a diameter of around 80cm.

Each Leg got 4 servos. Two of them you can see, the other two are inside of the balljoints.
I scaled the Tachikoma model up till classic 9g Servo fit into the balljoints. every thing else came afterwards.



While constructing and test-print of some prototypes i created a iOS Application to test the Actuator Ranges. I Have done some Videos of it.



Hope you like this Project.
This is my first Project i ever did with fusion 360 and my fist 3d construction since 2005 (3D Studio Max).

I am a professional iOS Mobile Developer so i will use a lot of the computing power of my phone and less of the power of the esp32 inside the Tachikoma. The "simulator" of the phone will be also the remote control for the real live version of it.

First Prototype prints of my fake-balljoint. inside the center piece i added a 9g servo. because i did not know how to fix the servo on the outer shell, i used a placeholder for a generic servo head. on the other side i added a ball bearing to remove weight from the servo.

That's pretty neat! And cool to see you playing to your strengths (iOS)

That sounds fantastic!

classic 9g Servo fit into the balljoints

Have you done the torque calculations? Will 9g servos be able to hold this design without overheating?

[TheMaverick]

No i did not. Not my profession. I use metal gear 9g with a torque of 3kg/cm. I hope this is enough.
