Title: How to sense the beginning and end of a ramp?
Post by: pagan457 on January 05, 2015, 08:31:23 AM
Hi guys,

I am a complete novice to building robots, yet have been tasked with making one for my Mechanical Engineering degree. I find it very interesting but am struggling to find the right sensors for the tasks it needs to do.

The robot will follow a white line on the ground using LEDs and LDRs going to a Wheatstone Bridge, and the output will control the Differential drive. I feel fairly comfortable (read: not really at all) with this section, but then the robot needs to sense a ramp, drive up it and sense when it reaches the top and come to a halt.

How would one implement this using tactile sensors?

We are using an Arduino Uno as the micro controller.

Thanks!!

(I will probably be back in the future asking for more help!)
