Here's Flounder:

my boy

the whole shebang

closeup of x and y servos and gripper

small demonstration

good timing


He is controled using an IFI robotics controler.
The wheels are aol cds.
I modified 2 servos to propel it.
the gripper is controled using the throtle wheel on the joystick.
The joystick trigger allows arm movement in 2 directions when you move the joystick.
5 servos powered by 3000mah 5? volt model airplane battery.
controler powered by 2000mah 7.2 volt rc car battery.


details follow:

Modified servos stop rolling when a signal of 171 is sent to them.
they only respond to plus or minus 30. any more does not increase speed.

my joystick centers at y=77 with wobble from 57-97
joystick x centers at x=106 with range 87-124
I Programed a recalibration so that the joystick effectively returns a smooth profile from 0 to 60, centering at 30 in both x and y, and stays at 30 in the wobble zone.

Turning speed has been adjusted to add or subtract 10 maximum. changed from 30.

range on arm movement limited to y=10-130 x=67-187.
