Step 3A Robot Magnetic Motor
The robot has four degrees of freedom. It can go forward and back, rotate left or right, move the gripper up and down, and open and close the gripper.
Pic 4- I relocated the four on board motors that it would normally take to do this by simply suspending a magnet horizontally on a two axis gimbal. Two 1/8"x1/8"x1/16" magnets are epoxied to a vertical shaft of wire that is bent to form one finger of the gripper. The two magnets are lined up to act as one magnet and create a single magnet motor. This is mounted in the smallest box which has the other gripper finger soldered to it.
The gripper box is mounted to the second horizontal axis of the gimbal with a 000 brass screw and nut. I used the screw so I could easily take it apart for adjustments.
An external magnetic field is mounted on a CNC type machine which can slide the magnetic feild along the x and y axis and rotate it horizontally and vertically. It could have been done with an electro magnet, but I chose to use a one cubic inch neodymium permanent magnet because it is the easiest and quickest way to create a large magnetic field in a small volume.
Pic 4c- So, with the north end of the tiny magnet in the robot facing toward the larger external south end of the magnet below it, the robot magnet follows fairly closely the motions of the external magnetic field.

And if you have no social problems but you are still smart and good at most scientific subjects? I wouldn't care if people call me geek, that's kind of what I'm trying to live up to. As long as this does not go too far. Then I think I'll be safe.
