Product Information

Now, when you type the characters 1-6 in the serial monitor, when the snake is turned on, the characters should affect the motion. Sneel is inspired by Protei, (protei.org), an international project for the design of a fleet of open source, robotic, unmanned sailboats. Sneel is a development of Protei_007. Make sure that after "PORT:" it says something like "usbserial-A700xxx". If not, select "RESCAN SERIAL PORTS". 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.

We used a similar setup as the instructable example for our photocell sensors. When getting one sensor, it is exactly the same. Just make sure the analog pins are placed in pins 2-5, as the motors will be using 0 and 1 (even though they are not plugged into them). We have used analog pins 3, 4, and 5. Where 3 and 4 are the directional sensors and 5 is the ambient sensor.Snakebots are used in situations where their characteristics give them an advantage over their environment. These environments tend to be long and thin like pipes or highly cluttered like rubble. Thus, Snakebots are currently being developed to assist search and rescue teams. When a task requires several different obstacles to be overcome, the locomotive flexibility of SnakeBots potentially offers an advantage.

S2CID 2337372. Try using strings to attach the base boards together. Allow boards to have around half-inch space in between the board so the snake has some free movement in between the boards. 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.

Temporarily attach motors and wheels to the head base piece of the snake robot. Mount the arduino components, breadboard, and the batteries to the head base piece of the snake robot as well. Test run the motors; set them to full power to begin with, and see if the wheels can break the static friction all of the extra weight is causing. Although the motors may seem like they have enough power when the snake is in the air, the motors will have trouble starting off. If the motors do not pull the snake head forward with reasonable speed, they will not be able to pull the rest of the snake with it. Be sure to buy strong enough motors before permanently mounting them to the wooden base! Use the loop part of velcro, sew it into the fabric. Use strings to sew the velcro into fabric. Sew it by pleating the fabric, so fabric can surround the base in a spherical manner. You can also apply loctite to some of the screws so that they dont come out. 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. Place the rubber into the vacuum reducer, and cut a small slit, large enough to pass the wires. Run the string through the vacuum reducer so that there is about 8 inches of string on the inside. There doesn't need to be too much on the outside because the tether will be located at the tail.When setting up multiple sensors, just use the same circuit example as the first one. Each sensor must have its own line to power and ground and cannot be a part of the same circuit; this will make finishing the snake easier in future steps. Also, make sure your resistors are the same, since this affects the analog readings, we need all the sensors to be reading similar values. 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.

I wrote a software library to easily generate wave locomotion based on oscillation. It calls on the Servo Arduino library to generate a sine wave propagating down the line of servos. It allows for modularity to change the sensory input, wave parameters, and number of servos.You don't have permission to access "http://www.argos.co.uk/browse/toys/electronic-toys-and-robots/c:30388/brands:zuru-robo-alive/" on this server. 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. 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 attaching wiring to the LEDs, make sure that the wiring attaches to the long or short side of each LED. You cannot connect different sides of an LED together on the same circuit, they will not be able to turn on. 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.
