Which Way Should I Go For Spot Micro?

I have completed the mechanical assembly of Spot Micro.    There are several versions for the controlling mechanisms used by various people.  Here is a very cute one that is done with an Arduino Mega as the controller with embedded code in the Arduino.   However, I have other options too such as either using a EZB V4 or a RPI with a servo Module and some reverse kinematics software. 

If I decide to use the EZB V4, this is not that different than the "Six" robot in complexity (maybe).   I have the parts and I am trying to determine which way to go.   The kicker will be designing each step of movement with frames using ARC.  I have not tried anything this complex control-wise.

Looking at the code, all of the positions you need are in there. The value of 0 in their code would be 90 in arc. Because they use - negative values for one way and positive for the other

That arduino code also has an IMU connected. Do you have one on the i2c port? Maybe that's why it isn't working for you. I'm guessing they use it for helping balance and such. Probably a good idea to use their code and control it via pwm from the iotiny if you can. That way you can build off the work they've already done rather than reinventing it.

I was looking at nallycat model, it inspired me.

I was wondering if this project is still active. I am considering making something like this.

Please see my other comment in this in the other thread. If you are looking on ways to program this or your other quad, you may want to look here. Might find something with some research.

Happy New Year Perry. Thanks for the info. I will check it out. It looks like a lot info is available

Nice work! One of the teams at my club, AC Robotics is also making a mini 'Spot' called Canis.
