My idea is to replace the humans with robots on magnets - like the maglev trains or just a couple smart wheels. Simple mathematical algorithms would adjust the robots to keep the contraption spinning constantly. Another idea along the same lines would be a smart track that simply moves a weight along the circle at the appropriate time.

Although it would be possible to generate power this way (using humans, hamsters, or robots), it will always require a higher energy input than it can output.
Furthermore, you often get much better efficiencies by removing intermediate steps. As the comments mentioned, you get better results if you go straight from PV panels to electrical power by removing the hamster wheel and hamster (robot).
Zeroth law of thermodynamics– If two thermodynamic systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other.
First law of thermodynamics– Energy can neither be created nor destroyed. It can only change forms. In any process, the total energy of the universe remains the same. For a thermodynamic cycle the net heat supplied to the system equals the net work done by the system.
Second law of thermodynamics– The entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium.
Third law of thermodynamics– As temperature approaches absolute zero, the entropy of a system approaches a constant minimum.
Of all the laws in science, this set of laws is probably the most inviolate of them all. If we ever find that these laws can be broken, then most of our understanding of how the Universe works is very broken. Basically you must throw out almost all theories and engineering design.
A humorous lay persons version of these laws is:
- You can't win
- You can't break-even
- You can't quit the game
