Product Information

When we replaces the wiring, we just twisted the end of the electrical piece and the wire together to connect the circuit. If you can, we recommend soldering these pieces together, it will create a stronger bond and be less likely to break. We needed to return some of our materials to the classroom, so we twisted the wiring together and wrapped each end in electrical tape to hold the bond together. If the steps got taller and more slippery, the snake would move more slowly and wriggle their front and rear body less to maintain stability.

S2CID 2337372. In this step we will be taking the three photocell sensors and using them to drive the motor speeds. In our code we will be refering the motors to Motor A or Motor B, based on where they are plugged into the motor shield, and the sensors will be Sensor 3, Sensor 4, and Sensor 5, based on where they are attached to the analog readings. Sensor 3 and Sensor 4 will be the directional sensors and Sensor 5 will be the ambient light sensor.First, measure the size of arduino uno and breadboard. After acquiring the size of arduino uno and breadboard, sketch the snake’s base with little hole on them so they can be attached with each other later on. The base of head should be theoretically bigger than the other base pieces to have balanced weight since the wheels will be attached to the head. Total 7 bases were sketched for our project.

Previous studies had mainly looked at snake movements on flat surfaces, but rarely in 3D terrain, except for on trees. Li said these did not necessarily account for real-life large obstacles such as pieces of rubble and debris that search and rescue robots would have to scale. To add more LEDs onto same circuit, the LEDs must be set in parallel to each other, and everything else will be the same. The same code will be used in this part also because nothing has changed. Run both buttons up through the vacuum reducer. Run the wire (containing power and ground) from the waterpump down through the hole in the vacuum reducer. So in total, the following wires should run through the vacuum reducer and the rubber pad : power and ground from both switches; one string; power and ground from pump. 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.

A robot snake has been developed by scientists in the race to advance the abilities of search and rescue machines. Use an electrical current to evaporate the water in it to "add" ballast. Something to test in a pool to see battery drain, I'm not sure how long batteries would hold up to it. Sounds like a decent theory to me. In this step we will be setting up three photocell sensors, all of these will be needed to complete the snake. Two of these sensors will become directional sensors, controlling the motors. The more light either the right or left sensor will have will control how much power each of the motors will receive, controlling the speed and direction of the snake’s movement. The last sensor will become the ambient light sensor, detecting how much light is in the room. This is necessary for each of the directional sensors so they can tell how much more light is being directed at them; and it is necessary for the leds, if the room is dark, the leds will light up. Once it is all the way on, I use the string on both sides to hoist the carbon fiber all the way into to the end of the vacuum tube. I tie a knot here to prevent slipping.

Again, in this step, we found it was easiest to draw out what we wanted timing wise, so we could easily see when to turn on and off each component. Allow the head base fabric to have extra 1 or 2 inch of indent so it has extra room for all the materials to be in the head.A ballast system of some sort... Maybe a remotely controlled intake connected to a tube that you can remotely open the front, and the rear port of the tube is an outlet only valve. Open the intake to let in water and make the device heavier so that it descends. The ambient light sensor will need to be placed near the center or end of the snake, at least far enough away that it will not sense any light aimed towards the head. The vibration motor will need to be as long as the snake itself so it will be able to rattle the tail. Acquire fabric of prefered choice. We used green fabric to make it look like somewhat more snake looking. Measure the size of balsa wood base, sketch it on fabric.

Now, when you type the characters 1-6 in the serial monitor, when the snake is turned on, the characters should affect the motion. To control the motors, we will be getting the base reading from all three sensors first (these are stored in photocellReading#). Sneel is the name of my snake / eel swimming robot. This is documentation of hardware, software and mechanical design of Sneel_003.Insert this into all four of the holes on the servo motor. Note that the rubber has a flat side. This side should be facing outwards. 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. Soldering iron, laser-cutter, scissors, sewing needle, small screwdriver, wire cutter/stripper, strong flashlight 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.
