Play around with sensors. Shine a flashlight into them to make the readings spike, cover them to make the readings drop. Your readings may have different values than ours, this is okay. Each sensor is different and it depends on the ambient light in the room at the time. Scientists noticed the wriggling portions provided stability to keep the snake from tipping over. As more of the snake reached the step, its front body section would get longer and its rear section would get shorter while the middle body section remained roughly the same length, suspended vertically above the two steps. They're based in convenient locations including supermarkets, newsagents and train stations. Plus they're often open late and on Sundays. Traditional SnakeBots move by changing the shape of their body, similar to actual snakes. Many variants have been created which use wheels or treads for movement. No SnakeBots have been developed yet that can completely mimic the locomotion of real snakes, but researchers have been able to produce new ways of moving that do not occur in nature. You should get an integer returned, corresponding to the baud rate xbee is set at. To make sure it is set to 57600, type "ATBD 6" then ENTER.
Researchers studied how the variable kingsnake – commonly found in deserts and pine-oak forests – climbed steps in Li’s terradynamics lab. “These snakes have to regularly travel across boulders and fallen trees – they’re the masters of movement and there’s much we can learn from them,” he said. Solder together a battery junction for the battery to connect directly to the pond pump, but solder the other on/off switch to the red wire between the battery and the pump. The battery sits right next to the Arduino. I'm using a servo motor shield from seeed studios, but I am sort of just using it as a perf board, but a convenient one because all the ground and power pins to my servo motor are already jumped together, with a screw terminal for the battery input. And ignore those wires hanging off the board - I had prefiously soldered on female header pins for another use of the board, so I removed them so I could use this here. I eventually clipped them off but you can see them in the pics.SnakeBots are currently being researched as a new type of robotic, interplanetary probe by engineers at the NASA Ames Research Center. Software for SnakeBot is also being developed by NASA for them to be able to learn by experiencing the skills to scale obstacles and remember the techniques.

Make sure not to do this before you are certain you are finished, because it is very hard to undo the screw once you've applied loctite. Also, the green loctite is a little less permanent.
NOTE: if Arduino is to be housed in the frotnt of the snake, connect the pins low to high from arduino to the servos that are most close to the head to far away) . in other words: the first servo (as in when the snake is moving ahead, the servo at the HEAD) should be digital pin 2, and the tail end servo shoudl be digital pin 11.
I think if you added a tank (or multiple outlet tubes) to the pump, then another pump to empty that tank/tubes you could use the first to take on water and sink and the other to empty the tank or both as forward propulsion but all of this would greatly reduce the longevity but for some applications like marine life monitoring that would probably be acceptable. Items that are not available in store will take 3-5 working days (excluding weekends and bank holidays) to be delivered to your nominated store.
Our snake will contain three groups of LEDs, each with 6-7 lights on each strand. To create groups of LEDs, it is the same process as creating a single group with only one LED in it. In our snake we used Pin 5, Pin 6, and Pin 7 to control the different strands of the LEDs. Also to save space on our breadboard, we connected each LED group to the same resistor that then connected to ground. This article needs additional citations for verification. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. Now, when you type the characters 1-6 in the serial monitor, when the snake is turned on, the characters should affect the motion. The vibration motor will need to be as long as the snake itself so it will be able to rattle the tail.
all you need now is the ability to dive... perhaps if you use gravity to cause the swimming motion my diving and surfacing you could also add longevity to the swim time. We recommend gluing the hook part to wood, because it is much easier to sew the loop part of velcro into fabric.
We then take the differences between Sensor 3 and Sensor 5 (and store it in photocellDifference1) as well as the difference between Sensor 4 and Sensor 5 (and store it in photocellDifference2). This will tell us how much brighter the directional sensors are from the ambient sensor. Since the light will be shinning on these sensors, the difference readings should tell us how much light is being directed at each sensor. When setting up the project in previous steps, everything was attached pretty closely to the breadboard. If we want out snake to be the full length of the base, we will need to create wire extensions for various portions of the electrical. Snakes have a bit of a reputation of being slimy and creepy (not true, but that’s the rep they’ve got). But for those of you who appreciate snakes for the critters they truly are, this awesome Robo Snake, in a choice of scarlet or green, might be just the fella you’re after.We found it was easiest to plan the speed controls out in a table before writing the if else statements. This was our table: Again, the code is similar to the photocell instructable. We create photocellReading variables to store the analog readings from the pins and then start the main loop. We will set the variable to the analog reading and print it out to see if it is working. We pause for 1 second, or else the reading will print out so fast we will be unable to read them. I screwed on the hose clamps onto the head and tail ends, but I am not sure this is necessary, it was just to be extra safe.
Great Deal
