Underwater robot won’t go down
I’m working on a project for my daughter she is doing a underwater robot but we got everything put together and we went to test it out the robot didn’t move at all the propeller spun but the robot didn’t go down is there anything we’re doing wrong?

Re: Underwater robot won’t go down
Hi Cari,
I assume you are working on this project:
https://www.sciencebuddies.org/science- ... ater-robot
A couple suggestions:
- There is a chance the propeller is spinning backwards (pushing the robot up instead of down). You can switch how the two wires are connected to the battery pack to make the motor spin in the opposite direction, then see if the robot goes down.
- The film canisters might be making the robot too buoyant. Try adding weight by letting some water into the film canisters, or taping some coins to the coat hanger, then try again.
Hope that helps, let us know if you have more questions!
