# Can I find the end effector position from joint velocities?

I would like to know if I can find the end effector position according to joint velocities. I have found joint velocities of a manipulator. I need to check if it is correct. So I need to know that how can I combine joints veloties and the end effector postion. Thank you in advance.

However, if you do know the forward kinematics as well as the joint velocities, you can use $$\dot{x} = \mathrm{J} \dot{\theta}$$ to determine incremental end effector motion.
