Arduino Robot memory

Hello.

After i have loaded a program in my Arduino Robot and try to load a new program there is a lack of space in the memory.
How can i delete a program out of the memory so i can load e new program?
Are the loaded programs to the memory-card in the color LCD screen?
Any help appriciated. Thanks.

Jack.
