plastic hole, sellotape & Polypropylene
« on: November 13, 2009, 03:42:51 PM »
I want to read your comments to my thinks
I was thinking to use very strong sellotape to connect some devices to the base of the 50 dollar robot instead of screws
The advantage that I see is that is more aesthetic the disadvantage that I see that if I glue it I can't separate
The near store of my house don't sale HDPE but the sale man
say that he have  Polypropylene and this is good for the 50 dollar robot
my friend tale me to use polycarbonate
what I need to buy?
How I can do hole in plastic without break it
Also my wheel is in plastic how I can do hole in the wheel to connect with screw the srvo to the wheel

I had a heap of trouble understanding that post...
Sellotape probably wont hold for very long if your robot has any weight on it, have you checked out double sided tape?
That stuff is gold!
As for plastics, get one that's not too brittle, more soft so you can drill it.

To attach the wheels to the servo you will need to drill holes in the wheel for the servo horn, then screw the servo horn to the wheel.
Polypropylene will probably do fine for the $50 robot...
