Hello, I am new to this forum and I need help with the coxa motor mounting in a hexapod robot.
I can see from different images of the pheonix hexapod that the spline of the motor is attached to the upper part of the body, but i can’t really recognize the bottom part of the body. Does the bottom part of the robot body touch the coxa motor, or the motor is just hanged from its spline?
Each servo using a bracket. The bottom of this bracket attaches to the bottom plate of the robot using a ball bearing . The only visual way to see this would be to look at the assembly guides.
Thank you for your help, but l have another question.
From the pictures i can see that the ball bearing is fixed, it does not rotate, and it touches the bottom plate. My question is: does the friction between the ball bearing and the bottom plate affect the movement of the motor?
Hint:
The split washer is between the BB and the bodyplate. The BB rotate freely.
Do you have a closer image to the robot from the bottom view showing what you are describing bedside the image in the assembly guide.
Thank you
Sorry for the confusing part, I was thinking how I did it on my original phoenix.
Attach the BB to the coxa bracket like this:
Should look like this:
This is how it look like under Phoenix before the bottom plate are mounted:
You see, the split-washer (lock washer) is the key to make the BB rotate freely.
Got it now?
What will happen if i didn’t use the BB at all, and just attache the motor to the upper plate by the motor’s spline
It will flop around as it has no structural integrity.
