Issues with sphere collider. Not sure exactly how it works

My character has Rigidbody, as does the sphere I would like it to move. The only was I could get my character to move the sphere was to give him sphere collider, too. However, this makes him very buggy and essentially spaz out, lol. I am a relative n00b to Unity, so any help regarding this would be much appreciated, as I can tell it's a great program.

Cheers,

 

While I'm no expert, I would think any collider on the character would do what you want.
Most of the tutorials use capsule colliders for characters, try that and sdjust the size to make it fit the character well enough and hopefully that works?
