What's up SOR! I have a question on how to seal my robot, so that no air or water can penetrate it's frame. On each side of the frame in my design, there are holes for the axles to penetrate through my frame wall. I have pillow block bearings holding the axle (one on the inside of the frame, and one on the outside, if you have any better suggestions about doing this, let me know) Any suggestions for sealing or waterproofing my robot would make me very happy! I am a bit of a beginner, so I might need basic terminology on complicated suggestions.
