There are 2 types of proximity sensors [switches]:
Inductive: These build a magnetic field around the sensor. Inductive proximity switches will only trigger when in the presense of a magnetic object (iron, cobalt, or nickel). Hint: This would be handy for detecting when you are over the steel mesh.
Inductive Proximity Sensors
Capacitive: These use an electric field to detect metallic and non-metallic objects. Every element has it's own dielectric constant (k). The sensor uses a reference material and detects a difference in capacitance. These can be used to detect other robots, containers, etc.
Capacitive Proximity Sensors
Remember, you can only use the sensors from Digikey or Future-Active. If they carry that manufacturer and model of sensor, then use it if you have them lying around.
If they are non-powered, they don't count toward the $200 electronics limit.
If they are powered, you have to count them.

How would they be "non-powered" ?

This reminds me a lot of how millennials are regularly called out for simply being younger and having different perspectives. In the end it's the ones who are calling them out in unprofessional in ways that end up embarrassing themselves and looking uninformed. - Karthik [more]
