The unnamed (yet) quatruped spider project
« on: October 20, 2019, 05:28:14 AM »
Hello all,

Been a few years since I actually built a robot and since I have never really tried to build anything with legs here we go.

Here is the plan so far:

- 12 DOF using MG90S microservos
- rpi zero w as brainz
- PCA9685 16 channel pwm driver for the many servos
- custom built battery pack out of two 3.6v li-ion cells with BMS
- an ubec to provide the 5v
- sensors TBD

I have all the parts in stock for a while now which is cool :D

Software wise (still in planning):
- the pi will run a custom build linux image
- the control software will be spawned from an earlier project I've been playing with written in golang using a framework called gobot.io
- more TBD

Currently I'm designing the chassis in FreeCAD, and I think I have a base to work with.

Of course this is all going to be 3d printed as usual :)

I'm going to create a github project and add all goodies in there once progress is made.

Enough for now I'll update once I have something to show.

Cheers!
TH

Sounds nice ! I'm looking forward to see this project going :)
If I may, I have a pretty good knowledge about walking robot, tell me if I can be of any help ;) Regarding your chassis, I would put more fillets in the corners, because this is plastic, you have to take care about weak points, especially in corners...

Hi,

It does not even try to compare to your Animabot that's a work of art :D
It's just a toy I'm working on and off and it's far from being even close to functional.

Regards,
TH
