Also, we discussed ways to dispossess hackers inside the robot, and we experimented with different bracing techniques. For support, we plan to add at least one casted, unpowered wheel, but we haven't decided where to put them yet. We anticipate problems in controlling when the device will push, since that requires a time delay from when the sensor detects a nonhacker to when the nonhacker reaches the area where it will be pushed out. Risks involved are that the device would push out a hacker or ignore a student.
Line following is our preferred method of navigation.
We plan on using five color sensors for accuracy. Since we will not be going onto the other campus, the issue of polarization has been set aside. We hope to use a long arm to sweep three of the four professors onto our campus. It will be opened and closed by means of pulleys and motors, and it will pivot via a servo. This arm will be able to rise and lower in elevation, and thus will also be useful in sweeping the jail.
