Hello, all...
I was the one that brought up using a gear differential to solve
another's problem. Here is a URL of a better design than mine.
http://www.nd.edu/~lego/grp4/backup/www/grp2/www/91geared.htm
Thank you.
PS: new project
Got the idea looking at the design for a Lego Joystick...
Robotic Fencing!
3 motors: 2 for XY movement of the 'foil', 1 for forward/back motion
3 inputs: 1 bumper, fore and aft, 1 'grip' on the foil, one 'pointe'
(the target)
Challenge:
Construct the Fencer along the Joystick lines, using one of the
long 'blacktron' antenna as a 'foil' (On). place a touch
sensor
to register that the 'foil' is in hand. 1 touch sensor
attached
to a fore and aft bumper, and finally, the 'heart', a MiniFig
shield, also on a touch sensor (Off)
Rules:
As in 'foil' fencing, only a touch to the heart scores,
and the fencer can only move along the lane (back &
forward). One addition, call it the 'swashbuckler
rule'
You can also score by disarming your opponent.
This can lead into Mindstorm Jousting, BattleMech Mindstorms, etc...
Or, perhaps I need (mental) help...

| (...) experience with this is kinda bad. I once did something quite similar, but when the drivetrain was loaded, one of the motors reversed, making the diff output zero. This happened, BTW, when I geared down the motors by 3:1 before passing the (...) (26 years ago, 20-Nov-98, to lugnet.robotics)
