| 5. | A biped using 3 motors, can run autonomous or remote controlled with a joystick. |  |
| 4. | A robot arm using 3 motors which can run point to point, learn its movement through teaching it (moving it manually), and it will playback the movement (approximately only). |  |
| 3. | Mybot is a compact vehicle robot that can patrol around, and also easy to replace batteries. I used it to test out RobotC (a text based programming environment to replace NXT-G) which I purchased in January. |  |
