[Solved] Arduino Robot not accepting new programs

Hello there.

Solving my problem was easy: I selected "Arduino as ISP" in the Programmer menu.

My Arduino Robot does not start the programs I am uploading to it. Whatever program I upload, the arduino always starts the example program, where the user uses the buttons to input commands. The program itself is not working correctly either.

I use Mac OS 10.10 and have set board to "Arduino Robot Control" and serial port to "dev/tty.usbmodem1421".

There are no errors uploading. I can see the LED/RX LED flashing for a second, the robot restarts... and end in the program I did not upload.

Does anyone have an idea how I can purge the faulty program from the robot and start over?

Thanks a lot!
