Servo Motor: Actuation Assignment 2

Assignment
 
Vaidyanath and I worked on this assignment together. The aim was to create a crawler using servo motor. We decided to use 2 servo motors instead of just one so that the crawler would be more stable.

Arduino Pot-controlled Servo Motorcycle: TermiCycle
 

Description
 

It definitely took me quite a bit of trial and error to be able to get the crawler to move forward. I had originally hoped to be able to have the crawler move its legs with a scissoring motion and have a piece of string attached to the motor that also lifted one leg off of the ground at a time. Unfortunately this was beyond my ability. What resulted was a crawler that inches forward, rotating two separate leg pieces. The tail is a functional accessory that counterbalances the crawler and prevents it from tipping over.

Description
In this assignment, we needed to build a crawler using the servo motor. The task proved to be quite tricky, especially since I was working with only one motor. My initial idea was to create some sort of stilts to mimic bipedal movements. However, after some rapid prototyping, this turned out to be difficult to do.
 

Description:
The goal of this lab was to learn to control a Servo motor. In part 1 of the lab, I learned to connect the Servo motor to the Arduino and control it using a potentiometer.
 

DESCRIPTION
In this lab, we controlled the angle of a servo motor first with the serial monitor then with a pot. Next, we attempted to make crawlers with balsa wood and rubber bands.
 

Description
This was a crawler that both Meena Vempaty and I built. It utilizes two servo motors, which rotate between 45 and 135 degrees through a loop in the Arduino code. One servo is flipped so that although they both rotate the same amount, one "leg" is moving forward while the other is moving backwards. The code is a modified version of the sample "Sweep" code, which can be found here: http://arduino.cc/en/Tutorial/Sweep
 

Description:
I made a cardboard figure with a circular cutout in its stomach that spins (using a DC motor) when a hand is close to it (using a photocell). One of the difficulties that arose was finding the lowest possible range of speeds for the motor.
