SUMMARY

This discussion focuses on simulating robot motion in water, specifically identifying the forces acting on the robot. The key forces include gravitational force acting downward, buoyancy acting upward, viscous drag opposing motion, and the force exerted by the robot to propel itself. The user seeks a straightforward model to compute these forces while neglecting turbulence in static water conditions.

PREREQUISITES
  • Understanding of buoyancy principles
  • Knowledge of viscous drag concepts
  • Familiarity with gravitational force calculations
  • Basic physics of motion in fluids
NEXT STEPS
  • Research fluid dynamics principles related to static water conditions
  • Explore mathematical modeling techniques for simulating forces on submerged objects
  • Learn about computational fluid dynamics (CFD) tools for simulating robot motion
  • Investigate the effects of varying robot shapes on drag and buoyancy
USEFUL FOR

Engineers, robotics developers, and researchers interested in fluid dynamics and robotic motion simulation in aquatic environments.

I am trying to simulate a robot moving in water.
I need to determine exactly what forces will act on the robot from the water (bouyancy is obvious, and understood).
I need a simple model that will enable me to compute what force the water will exert on the robot, when one of its parts move.
(I neglect turbulence in the water. Also, the water is static, not flowing!)
Thanks.

The forces acting on you robot will be:
1. Gravitational (vertically downward)
2. Bouyancy (vertically upwards)
3. Viscous drag ( opposite to the direction of motion)
4. Force, your robot will apply to move.
