Hexapod Robot

This is the Hexapod robot that I completed recently, it is composed of 12 servos running off of a EZ-B, I am currently using the script for EZ-Robot's Six Robot, although I am also working on developing my own.

Also please vote for me in both the Tech and Robotics contests.

To build this, you will need:

-a piece of cardboard that can make at least 2 20 cm x 20 cm squares

-12 standard 180 degree servos

-12 servo lever attachment things

-2-3 packs of paper smoothie straws (the large ones) (from http://www.greenmunch.ca/)

-1 pack of standard size paper straws (from http://www.greenmunch.ca/)

-one Ez-b and power shell

-1 7.2 volt LiPo battery

-1 ultrasonic sensor

-a bunch of standoffs (straws could be used in place of these)

-12 machine screws (same size as the standoffs) (only need if using standoffs)

To build this, you will need:

-a hot glue gun and glue sticks

-a drill and drill bits

-a sharpie or pencil

-an x-acto knife or some way to cut the straws

-phillips screwdriver

-flat head screwdriver

-a table or desk

-a computer with Ez-builder installed

Note: if you are using straws in place of standoffs steps 3 through 5 of this part are irreverent

Note: steps 2 through 5 have to be repeated for both hexagons.

1. start out by cutting two identical hexagons with side lengths of 10 cm. (if you don't know how, just google it)

2. erase the lines

3. then measure 1.5 cm down the sides of each hexagon starting at the corners.

4.connect the lines and mark the middle.

5. drill out a hole in the middle of each line (it is very important that the hole barely fits the machine screws, if it is to big, the screw head will just slide through)

Note: step 7a is for standoffs and step 7b is for straws

6. attach some standoffs together or cut some smoothie/large straws so that you have 6 pieces, each 4.7 cm in length

7a. put one machine screw through each hole and attach them together using the standoffs.

7b. glue the ends of the straws with the ends centered on the middle of the lines drawn earlier

THE BASE IS NOW FINISHED

1. Center each servo and screw on the servo arms. (make sure they are pointing directly away from the servo)

2. cut 6 pieces of large straw, each 0.6 or 0.7 cm in length and glue them onto the servo, exactly opposite of the bit sticking out of the servo.

3. find the middle of each side of the base.

4. glue the servos with the arms attached so that only the tabs on the side of the servo is inside the base. (this side is the top)

5. cut 6 pieces of large straw, each 9 cm in length and 6 pieces of regular straw each 1 cm in length.

6. glue one 1 1cm piece of straw to each 9cm piece of straw at 90 degrees at the very end.

7. flip the robot over and insert each 1cm piece of straw into each 0.6cm piece of straw and pull the opposite end of the 9cm piece of straw towards the middle of the base and glue it (repeat for each servo)

1. cut 6 more 0.6 or 0.7 cm pieces of large straw and glue them opposite of the movable piece that sticks out (same as before)

2. glue the second set of servos onto the first set by gluing them so that the tabs sticking out of the sides interlock. (see picture above)

3. for the feet, you can use almost anything you want or make something, the main guideline is that they should be roughly 8 cm tall x 3 cm wide x 1 or 2 cm thick

YOUR SERVOS ARE NOW ADDED

1. cut a hole in the top of the base just barely big enough for the Ez-B.

2. stick the Ez-B and power shell in and plug in your servos.

3. glue the ultrasonic sensor to the base (I put a lego piece in between the sensor and the base just as a spacer and an easier way to attach it)

YOUR HEXAPOD IS NOW COMPLETED
