Product Information

This instructable is technically a 2-in-1, in that I explain how to make 2 different versions of a robotic snake. If you are only interested in building one of the snakes ignore the instructions for the other snake. These 2 different snakes will be from here on referred to using the following phrases interchangeably: 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. Past winners have occasionally gone on to further develop their concepts, and a couple of those are even being considered for integration into upcoming NASA missions. Other times, projects languish after team members graduate. According to Kevin Kempton of NASA’s Game Changing Development Program, one of the competition’s lead judges, it depends on the motivation of team members. “I try to tell the teams, the next step is to look for announcements of opportunity,” Kempton says. “NASA is always looking for low-cost payloads.” Since the servo has a range of [0,180] degrees we must ensure that the above values don't give an output below 0 or above 180. The following while loop is used to constrain the amplitude to with in these bounds. Mathematically we must satisfy this condition: |offset|+|amplitude|<=90 while(MaxAngleDisplacement>90){ 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.

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.

The team created the robot to mimic the snakes’ movements. They say that compared to robot snakes from other studies, their creation is more stable than all but one, and came close to matching a real snake’s speed. Kano T, Yoshizawa R, Ishiguro A.

In the code, you can see we have a long list of if else statements controlling the speed of each motor. This code works for our snake and our photocell sensor/motor combination. If you have changed the materials for your snake or find that these values don't work for you, when feel free to change the values until you find speed control that works for you. Our snake is meant to work in low light and at a pretty fast speed. If you want your snake slower, for example, you may want to widen your range of lrValues in the if else statements, so that it will take a high powered light directed at one sensor before the motors reach highest speed.

The assembly process is mostly the same for both versions of the snake. The only difference is the in the 2D snake each motor is rotated 90 degrees relative to the previous, whereas in the 1D snake all the motors are aligned in a single axis.Ming Luo 1 Zhenyu Wan 2 Yinan Sun 2 Erik H.
