When I wrote my new book Make: Minecraft for Makers, you know I had to include a monster Creeper project. Here’s how you can build a motorized Creeper, with a metal skeleton and wooden skin. Aside from the fact that this thing most certainly doesn’t blow up, you’ll love it, and you’ll learn a lot about robotics and Arduino along the way. Let’s get to it!
The Creeper consists of a robot chassis kit with add-on parts creating the mob’s distinctive armless body, with a servo motor to move the head around. Begin by taking a look at the Creeper in-game. Just be sure to stick to Creative mode or you may find yourself getting blown up!
The Creeper has a cubical head 8 pixels on a side, a 4×8×12 body, and four 4×8×4 legs. It’s actually a pretty elegant design, which makes it a breeze for building a physical re-creation.
The Robot Creeper seems super challenging at first. The thing has to look like a Creeper, ideally proportionate with the game element. At the same time, it also has to function as a robot. In other words, regardless of its outer appearance, the Creeper has to be able to fit all the necessary robotic components, particularly the chassis kit we’re using for the base.
I began with the Actobotics Bogie Runt Rover, a kit available for around $70 that comes with a chassis, six motors, and six wheels. The assembled rover’s chassis measures 6″×9″, though the wheels project a little, and it rides fairly high: 6″ off the ground. With those measurements I was able to decide the size of the footprint: 12″×8″ — conveniently, one inch per pixel.
Applying the one-inch scale across the whole robot makes for a 12″-high, 8″-wide, and 4″-deep body, an 8″ cubical head, as well as four legs 6″×4″×4″. However, for the legs I decided to merge the front pair and back pair into 8″-wide blocks — the thing is going to roll, not walk. The image above shows my final design. I created vector files to be used on a laser cutter, but you could simply cut the pieces from wood, or get creative with other materials — recycle those Amazon boxes and use some packing tape to knock out a cheap, simplified version.
Next, we need to design the robot’s electronics. What will be its functionality? How will it be controlled? The Minecraft Creeper is known for blowing up, and clearly that was out. It also turns its head, and we can do that by putting a servo motor inside the body to turn our robot’s head. The Creeper also has eyes that turn red when it’s about to explode. That’s easy! We’ll put NeoPixel Jewels in the head.
Under the hood I stuck with the classic Arduino Uno, with a motor control shield sitting on top. This add-on board helps the Arduino manage the high voltages needed to run motors, and it simplifies controlling them.
Speaking of control, I’m making a basic controllerthat connects to the robot via a trio of wires.
1. ASSEMBLE THE ROVER KIT
Begin the build by tackling the Bogie Runt Rover kit. There’s a great assembly video at servocity.com/bogie.
2. ADD THE BODY BASE
Attach one 3¾” piece of channel to the center set of mounting holes on the rover, using a large square screw plate and four screws added from the underside.
3. ATTACH THE HEAD SERVO
Use the standard servo plate to attach the servo motor to the channel. While you’re at it, you can attach the coupler that attaches the servo’s shaft to the D-rod.
4. ATTACH THE BODY CHANNEL
Secure the 9″ channel to the 3¾” piece you already attached. Use a dual screw plate as shown.
5. ADD THE SUPPORT BEAM
Attach the second 3¾” channel at the top of the 9″ piece using the second dual screw plate.
6. ATTACH THE BEARING
Attach the bearing so that it lines up with the servo’s shaft.
7. SECURE THE D-ROD
Thread the D-rod through the bearing and secure it in the servo’s coupler.
8. ASSEMBLE THE FEET AND BODY SKINS
The Creeper’s skin consists of a series of laser-cut wooden box shapes that rely on gravity to stay on the robot.. The skins are all made from ⅛” plywood, except the head base is ¼”.
You can find the blueprints among the downloads for my book at github.com/n1/MinecraftMakers, in the Chapter 9 folder.
9. PAINT IT!
It’s time to paint the body and feet that delightful Creeper green. The image below shows my creation with one coat of paint.
10. ATTACH THE SKIN
Once the paint is dry, drop the skin down on the robot with the 1/4″ rod projecting from the top. It should fit nicely without any problem.
11. ADD THE HEAD BASE
Use 1/4″ plywood, 8″×8″ square. Drill a 1/4″ center hole as well as the mounting holes for the setscrew hub; then secure the hub with the small square screw plate.
12. BUILD THE HEAD
Assemble the panels of the head. Once again, a plywood box! This one needs holes for eyes.
13. PAINT THE HEAD
Paint the outside of the head green to match the skin, but also add the black parts of the face. I suggest painting the inside of the head black so the eyes look blacker.
14. INSTALL THE ARDUINO
Find a spot on the underneath of the robot to install the Arduino using #4 hardware. You can drill into the Bogie’s ABS chassis if you want, or use one of the available mounting holes.
15. SEAT THE MOTOR SHIELD
The motor shield sits right on top of the Arduino, with the shield’s male headers plugged into the Arduino’s female headers.
16. CONNECT THE SERVO
Attach the servo wires to the motor shield’s Servo 1 pins.
17. MOUNT THE 9V BATTERY
Attach the 9V battery to the chassis but don’t plug it in yet. (the image shows it plugged in)This powers the Arduino but not the motors.
18. ATTACH THE BATTERY PACK
Attach the 4xAA battery pack to the chassis and plug it into the motor shield’s Power terminals, as shown.. This pack powers the motors separately.
19. CONNECT THE MOTORS
You have six motors, three on the left and three on the right. Combine the leads as you see in the image below, so that the M3 motor terminals control one side, and M4 controls the other. The Bogie’s motors are modest in size and stacking them won’t strain the motor shield’s capabilities.
20. WIRE UP THE NEOPIXEL EYES
You’re using two NeoPixel Jewels for eyes, to create the telltale glowing red that signals an imminent explosion. Connect both Jewels’ VIN (red wire) and GND (black) pins to the Arduino’s GND and 5V pins. The data wire goes from digital pin 6 on the Arduino to the IN pin on the first Jewel, and then from OUT to IN on the next eye.
Arguably one of the gaming industry's most famous characters comes from a game about surviving with blocks. He’s mean, he’s green, he’s got an explosive personality. Minecraft’s creepers are nothing to mess with.
the original creeper was originally brought into Minecraft on August 31, 2009. Accidentally altering the length and height of a pig, he reversed their numbers. The pig was skinny and tall vs. Short and fat. He was grey and didn’t have a name. Notch liked the flaw so much he decided to implement it into the game and create a new hostile mob.
the creeper was given life with a shade of green and a scary face to make players shake in fear! Creepers are aggressive by nature and will actively spawn more at night (Or in an area with light levels less than 8). They will roam around in the day and if they get close enough to you, they’ll gladly explode and attempt to take you with them as they end their life. If a creeper is struck by lightning, they will become a charged creeper.
Notch has stated that he likes to think that creepers would feel “crunchy, like dry leaves”, and that he likes to imagine that creepers would be made of leaves or similar. He’s not quite sure why they explode, however.
When a creeper is within a block of a player, the creeper will create a hissing noise and will begin to explode. If you unexpectedly hear a creeper’s hiss, your best bet is to get out of the area immediately as he will deal a high amount of damage if the hit is direct. If you are wanting a creeper to explode for whatever reason, use a flint and steel on the mob and it will immediately force the process. If a creeper is stuck in a cobweb, it will take them longer to explode.
there are many ways to kill a creeper, some ways more beneficial than others. When a creeper is killed, they have a chance of dropping anywhere from 0-2 gunpowder. If a creeper is killed by a charged creeper, the creeper killed by the blast will drop a creeper head. If a skeleton kills a creeper with an arrow, the creeper will drop a music disc.
If you want to kill a creeper quickly, your best bet is to get as many critical hits on them as you can. Either do it in head-to-head combat with a sword and jump back after hitting him directly or do it afar with a bow and arrow. Both ways are great in terms of dealing with these ferocious mobs, but if you don’t deal with the problem correctly, you may have a hole in the ground!
Something that has been tested many times is how much armor is actually needed to withstand a direct hit from a creeper point-blank. If you were on the difficulty ‘hard’ and were attacked with a point-blank explosion from a creeper wearing full iron armor, you would have lost 19 of your 20 health points (Half a heart).
Charged creepers are a much more dangerous mob to mess with. Charged creepers will create an explosion twice as large and deal much more damage to the player when hit. Your best bet to kill a charged creeper is at range with a bow and arrow.
Creepers don’t seem like they would be too afraid of much, but surprisingly they’re afraid of tamed cats and ocelots! If a creeper is within a certain range of said animals, they will run away from them (Around 30 blocks). A tip to survival is to definitely have a cat with you if you are going into creeper heavy territory.
Creepers are not a force to be messed with unless you’re ready. Make sure if you’re going to go up against one of these beasts, be prepared and definitely do not hold back. Creepers are very dangerous, but let’s face it, they’re just a bunch of scaredy-cats!
Mob heads may be interesting decorations but to obtain them you would need to blow mobs up with a charged creeper. Until now With this data.
Banners are crafted from wool and a stick. The banner will be the same colour as the wool you use.
Banners can be placed on the ground or on a wall, or they can be used to place a design on a Shield.
Patterns can be added to banners using dyes. Place the dyes in the correct pattern in the crafting grid. The banner you wish to add the pattern to can go in any free slot on the grid.
The patterns have some rather strange names when you mouse over them. These names come from the language used to describe the coats of arms painted on knights’ shields in mediaeval times. Here is a guide to this language
Banners with half, stripe and cross patterns.
Divide your banner in halves horizontally, vertically by placing a pattern of 6 dyes, arranged to the left, right, top or bottom of the grid.
Divide your banner in halves diagonally by placing 3 dyes in one of the four corners.
You can make a single stripe by placing a line of 3 dyes either horizontally or vertically.
Divide the whole banner into multiple vertical stripes with 4 dyes as shown below:
Can you guess how to make the two types of cross? It’s not hard!
Banner gradients and Field Masoned.
A gradient is made with a pattern of 4 dyes; flip the pattern to make it go from bottom to top.
To make a brickwork pattern, combine your banner with a brick block.
For a coloured pattern, use bricks and dye together.
Banners with borders and a variety of shapes and icons.
Plain borders are made by placing 8 pieces of dye all around the edges:
A fancy border can be made by combining a banner with a piece of vine. To make it a coloured border, use a piece of vine and a dye.
Squares in each corner can be made by placing a single piece of dye.
A chevron is a triangle at the top or bottom, made with three pieces of dye as shown:
A similar pattern of three dyes will produce a row of teeth at the top or bottom.
A single piece of dye in the centre will give a small round spot.
Four pieces of dye gets you a lozenge shape.
Finally, a number of items can be combined with banners to add a charge (a symbol or icon).
Add the item to a banner to give an icon in black:
Combine the item, a banner and a dye to get a coloured icon:
What icons are available?
Once you’ve added a pattern, you can take the new banner and add another! Banners can hold 6 patterns, so you can build up quite a complex pattern.
Maybe choose a nicer pattern than this though!
Once you’ve made your banner, you don’t have to go through the whole process again. You can copy your design onto a blank banner, as long as the blank banner is made from the same colour of wool.
DIY Minecraft Costumes- Creeper, Steve and Zombie Costume
For the past three years my kids have been asking to be Minecraft for Halloween. We usually have a family theme each year, so I usually can convince them to do something else. Well this year we aren’t doing a family theme, so I let them have their Minecraft costumes. They picked a creeper, Steve and a zombie. They were easy to make and the best thing about them is they only cost $5 each to make, woohoo!! The heads are about $20 each so and they aren’t nearly as cool as these ones :). I ended up making them a mask, a hat and a treat box (since they always seem to want a prop, I figured they might as well have a functional prop).
For the eyes, I cut holes at the eyes and then used a black and blue mesh fabric. I put it behind the hole inside the head and glued and taped it inside the head.
For the shirts I just used regular boys’ shirts. To save some money, I found some white shirts at the dollar store and used some Rit Dye that I had left over from another project to dye the Steve and Zombie shirts (and because I wanted them to be the perfect blue).
