Does your robot have to come up after exactly 2.5 mins, or after 2.5 or 2.5 at latest?
Calculating Force to Lift Cuboidal Object in Water: 1.1 Kg
Click For Summary
SUMMARY
The discussion centers on calculating the force required to lift a cuboidal object weighing 1.1 kg submerged in water, with a volume of 1050 cm³. The object experiences an upthrust of 1.05 kg due to water density, meaning the motors only need to exert a force equivalent to 0.05 kg (approximately 0.49 N) to lift it. Participants explore practical solutions for lifting the object, including using electric DC motors and flotation systems, while emphasizing the importance of measuring forces in Newtons rather than kilograms. The conversation also touches on the design of a submersible robot that can autonomously rise and sink in water.
