Any other advice is greatly appreciated it. Thanks jehan though.

The track is the same width at all points and the narrowest turn is 90 degrees. The wide turns won't give a problem. My estimate of how long the arms should be was at least the width of the wheels. So when hitting that 90 degree turn it will detect it before it is too late to turn. If the arm...

Yeah, that's basically what the sensor is. The sensor, motors, and circuit is all already made, I just have that physics question of how long and at what angle should the arms be. But you are absolutely right with the sensors, those are exactly what they are.

It's off the ground, about 5 cm off the ground. Not so big so if the bot falls it breaks apart, but enough so the sensor can react. It's basically a platform.

Take in consideration that it is not my best drawing, haha. I just made a quick sketch, but I believe the proportions are close.

Hi. I'm building a small automated robot that will only work with 2 motor, 2 wheels, and 2 sensors. My goal here is for this little robot to make through a track without falling off. Here's a little sketch I drew on Paint to help understand what I'm saying. Each sensor will be connected to a...

I am still back to the beginning. I know 'what' to do, I just don't know 'how' to do it. What numbers do I use, what equation?

In the x direction T1 - T2 = 0? And in the y direction. T1 + T2 = mg? So i'll have to use Trig to find the numbers for each axis, but the only number I have is length, how would that help me?

I have one drawn right in front of me right now, but I just don't know what formula to use, or how to find ALL of the forces in both axis.

Oops, there I edited the first post and it should be there now. Also, after I posted that second post, I realized that nowhere in there it had any variables for the length of the string, which likely play a part in here. So I think I'm not supposed to use that equation.

Would this work? T x cos θ1 + T x cos θ2 = mg, where θ1 and θ2 are the angles the two sides.

Homework Statement A ball of weight 5 Newtons is suspended by two strings as shown above. Determine the magnitude of each of the forces, T1 and T2. (Note: sin 37° = 0.6; cos37° = 0.8) Homework Equations T = mg The Attempt at a Solution I couldn't go anywhere because I need a...

OK, so I had this physics homework question about 2 weeks ago, and I thought I would post it here to see if anyone can figure it out. Note: this homework assignment is overdue and can't go back, I am just asking to see if anyone can get it. Reason I am asking is because I asked 2 physics...

WOOOOO! Finished the problem! Thank you guys so much! I really appreciate it.

d=v_{i}t+.5at^{2} ? Using that equation, I get that the v_{i}=32.86 m/s. Am I on the right path?
