Character getting stuck on curbs..

Hey guys,

My character works very well except when he hits something tiny, he just gets stuck. How can it automatically move up small things like this? Ive tried a box, capsule and mesh collider and nothing seems to be able to do it.

What I'm talking about.. Notice its just his legs. lol..

You guys are lifesavers!! Thanks!

The movement script.. using UnityEngine; using System.Collections;

 public class Addbuttons : MonoBehaviour {
 void OnGUI()
 {
         //Forwards
     if (GUI.RepeatButton(new Rect(65, Screen.height-125, 70, 30), "Forward") == true)
     {
         GameObject Player = GameObject.Find("objPlayer");
         Player.transform.Translate(transform.forward/20 , Space.World);
     }
         //Backwards
     if (GUI.RepeatButton(new Rect(65, Screen.height-50, 70, 30), "Backward") == true)
     {
         GameObject Player = GameObject.Find("objPlayer");
         
         //Player.transform.Translate(transform.forward/20 , Space.World);
     }
         //Left
     if (GUI.RepeatButton(new Rect(10, Screen.height-90, 70, 30), "Left") == true)
     {
         GameObject Player = GameObject.Find("objPlayer");
         Player.transform.Rotate(0,-2,0);
     }
         //Right
     if (GUI.RepeatButton(new Rect(120, Screen.height-90, 70, 30), "Right") == true)
     {
         GameObject Player = GameObject.Find("objPlayer");
         Player.transform.Rotate(0,2,0);
     }
 }
     
     // Update is called once per frame
     void Update () {
     
     }
 }
