Due to the update of Petimo Specification, a graphical user interface (GUI) is used in the menu system design . It is because the GUI is intuitive and easy for the user to operate the robot. Small graphics icons are widely used in the design to give user intuitive view. As the name of Qoot Robot, cuteness is added into design to make the menu interface lively and attractive.
As a result, we change the OLED to a color graphical one, DD-6448BE-2A, which can fulfil the new requirement.
The main feature as follow:

·         160 x 128 resolution, 256/65K true to life colours, PMOLED screen.

·         1.7” diagonal size, 52.0 x 32.0 x 6.3mm. Active Area: 33.6mm x27mm.

·         No backlighting with near 180° viewing angle.

·         Easy 5 pin interface to any host device: VCC, TX, RX, GND, RESET

·         Voltage supply from 3.6V to 6.0V, current @40mA nominal when using a 5.0V supply. Note: The module may need to be supplied with a voltage greater than 4.0 volts when using it with a SD memory card.

·         Serial RS-232 (0V to 3.3V) with auto-baud feature (300 to 256K baud). Rx line has built in series current limit resistor and a pull-up resistor.

·         Powered by the 4D Labs GOLDELOX processor (also available as separate OEM IC for volume users).

·         different operating platforms; the Serial Command platform (factory default) or the 4DGL (4D Graphics Language) platform.

·         Optional USB to Serial interface via the 4D micro-USB (μUSB-MB5 or μUSB-CE5) modules.

·         Onboard micro-SD (μSD) memory card adaptor for storing of icons, images, animations, etc. 64Mb to 2Gig μSD memory cards can be purchased separately.

·         Rich set of built in graphics commands and functions.
