Servo Motor: Actuation Assignment 2
Description
I made several iterations with the same idea of a inch worm that crunchs and then expands to move. Getting the weight and pulling force right was difficult and different for every surface. Moving the servo motor to the back helped as did copious rub band pads.
Getting the speed right was also took some refining, but it crawls now - at least on some surfaces.
Description
For this assignment I used a potentiometer and servo motor to make a manually controlled limpy crawler. I call it a limpy crawler because it only has one leg, so it sort of limps around. I made the leg out of one half of a clothes pin, and attached it to the servo with zip ties. Because this did not crawl very well on its own, I attached a small rubber foot to provide better traction. The Servo body was put on a sponge to help it glide along a little better.

Well, I tried all night to get this toy dog to crawl around with a harness, but I couldn't get the motor strapped on tight enough to his back so it never quite worked.
Materials:
Super Glue
Servo Motor
Wood
rubber bands
Metal eye holes
wires

Description
I was trying to mimic a crawling of a insect(an itsy bitsy in my son's baby language). I could mimic only the shape of it, not the actual mechanism.
After series of trial and errors (+ tiresome from my hand controlling the pot) I designed this itsy bitsy with two pushing legs and two guiding legs. I built four legs HAND-made from wire paper clip, and I added eraser pieces for the feet of pushing legs. I put some putty thing on top of the motor to fix the clip wires.
Description
I ended up having a excavator-like crawler because I need the servo to be in the middle. Before that, I tried numerous types of crawler: servo on the side, two clips on each side that were tied on a popsicle, but they all failed because they kept going in circles. This one more or less still does, because it's hard to keep the clip straight. But sometimes with good control it can go straight forward pretty fast. Since the servo is hanging in the front, I added the batteries to balance the weight.

My original creation failed: I made a crawler using a pill bottle, pipe cleaners, tape, and the servo motor. Kept falling after the first couple tries....
so I made another: It has a stick connected to the motor with a bobby pin attacked to that. I attached rubber band to one leg. Because the bobby pin has two uneven legs, one of the legs propels it forward, while the other grabs the table. Much more stable and successful than the previous try....
Components:

The stride of the crawler is set by the potentiometer. The servo motor rotates from 0 degree to the degree set by the potentiometer. User first rotates the pot to a value between 0 to 179 degree, then keys in 's' in the Serial monitor to set the stride. The servo then continues to rotate to that degree to make the crawler crawl. To quit crawling, user can key in 'p' in the serial monitor. This will stop the crawling

Crawling dog using a servo motor attached to a wooden stick to push it along. Hardest part was building something that attached the wood stick to the servo motor because any little tilt in the wooden stick resulted in the dog going around in circles and not in a straight line.

For this assignment I created a happy, crawling bug with long, wooden legs.
