1. The problem statement, all variables and given/known data So basically I have a project where I have to basically make a vehicle that can tow 2 objects and across a 30ft fishing line. The line will be pulled tightly. After we've demonstrated our vehicle's ability to go 30ft, the line will be angled at a slight incline. Definitely less than 45 degrees. We can use battery powered items for our vehicle. Do you have any ideas? 2. Relevant equations 3. The attempt at a solution I was thinking use a remote control car to go across, however the main problem with that one would be how to connect it to the line without restricting the forward motion of the car. Any suggestions for this would be greatly appreciated.
