I would like to add Pan/Tilt to a Tablet to be the Robot Interface
besides the rotation & lever servo i will need: Clip'n'Play Adapter Plate Extension Cube
similar too:
The tablet is 7" and the weight is 370g (0.82 lbs)
some questions/issues:
- Tilt servo (Lever Servo) can a EZR HD servo handle 400g ?
- I will need a frame similar to (thingiverse):
but with a female EZ-BIT
I'm not familiar with 3d tools, zero "nada" skills!,
anyone did something like that ?
can someone build or adapt an existing frame to support a 7" tablet (119.77 x 196.33 x 15.36 mm) ?
other ideas ?
any help/ideas will be appreciated
@oldbotbuilder,
lever on the back.
Don't you think the servo has more stress to hold the tablet versus the initial setup, bracket bellow the tablet ?
I think the center on the back would have less stress because the weight is distributed like @oldbotbuilder mentioned
@ptp,
Yes, that should work.
update:
@Dj:
once again thanks for the help.
front:
back 1
back 2
detail cube:
I was in a rush and i sent the first design (without the back clip & play) to shapeways to print, one day after entered in "production" and they didn't let me change the file, and it took forever (only got it last weekend). I hacked the back with a thin abs plate and a female adapter plate.
@DJ: Does exist a MALE Clip'n'Play Adapter Plate ?
I found it (different color)!
I'm using a cube but without it will improve the stability.
Guys,
Any thoughts ?
That looks real good! And it fits well?
@ptp There will be a lot of side load stress on the pan servo. You may want to look in to the servo blocks at ServoCity.
Servo Block
@DJ:
It fits perfectly i used some foam tape inside the 3d print case to avoid scratching the tablet.
@RGordon:
yes that is the weak link (horizontal servo), i think the stress is higher when the base starts to move, also i need to minimize the vibration.
I'm using 80/20 frame for the robot spine and head, i will need to add some actobotics frames to help the mounting, unfortunately i'm not familiar, so i need to do some research to avoid spending extra money.
Are you familiar with their products ?
Their products are great. The servo blocks are by Actobotics. The servo blocks take the strain off of the servo by isolating the lateral load from the servo spline and case. I have not used these yet but, this looks to be what you need for at least the pan servo. See the link in the post above and the video to help you decide. Take some time to look over the ServoCity website. They have some very cool stuff.
You will have to choose what type of servo spline shaft hub to match the type of servo you are using. They have a guide somewhere on the website to help with that.
