Accessories and Expansion Modules
The RP6 offers a very flexible and universal expansion System. It is based on the two wire I2C-Bus, which allows you to connect up to 127 devices to the Robot. You can add several expansion modules on top of the Robot, which can be mounted symmetrically on front and rear. AREXX Engineering plans to release several expansion modules with additional sensors in the near future. Of course, there is already the Experiment module for your own circuits included with the Robot and also available seperately (Conrad Electronics odering code: 191537).

You can easily add an additional Microcontroller to the Robot with the RP6 CONTROL M32 (Conrad Electronics odering code: 191550). The RP6 CONTROL M32 offers an ATMEGA32 clocked at the maximum 16MHz, an external 32KB SPI EEPROM (non-volatile memory), and 14 free I/O pins, 6 of the I/Os are useable as Analog to Digital Convertor Channels. You can connect any HD44870 compatible LC-Displays to the Display Port of the RP6-M32. Also larger displays than the 2x16 LCD on the photo can be used!
The non-volatile EEPROM can be used for data logging or Bytecode interpreters like the Java NanoVM:

Beneath the accessories manufactured by AREXX Engineering, there are several things from 3rd party manufacturers that can be used for RP6.

The Robot can receive IR Codes in RC5 Format. One of the example programs allows you to use an universal IR Remote to control the Robot like a normal RC Car. For example the "Promo 8" from Conrad Electronics, ordering code 340720-62 or similar programmable remote controls.

You can use external battery pack chargers to charge the 6 required NiMH accumulators inside the Robot. This is more comfortable than removing the mainboard everytime. For example you can use one of the following chargers:
  • Voltcraft 1A Delta Peak fast charger, ordering code 232622-62
  • Voltcraft 2A Delta Peak fast charger, ordering code 233085-62
  • Ansmann AC48, ordering code 250125-62
  • Ansmann ACS 110 Traveller (or ACS 410), ordering code 512067-62
Of course any other Battery pack charger that is capable of charging 6 NiMH Cells in series and has a suitable 5.5mm connector can be used! We recommend to use Microcontroller based Chargers.
