For long-term experiments (e.g. genetic algorithms) the Koala can be powered and controlled via a tether cable using our Koala External Power Supply.

The Power Supply exists in two models: the Standard model with a simple tether cable, and the Deluxe model which includes a rotating contact to prevent the cable from twisting.

The external power supply package includes:

• Power supply (100-240VAC)
  
• Cable to connect the power supply to the wall outlet
  
• Tether cable to connect to the Koala robot
  
• Optional rotating contact to avoid cable twisting (Deluxe model only)
  
• A power supply converter that replaces the battery on-board the Koala
  
• The configuration is as shown below (RS232 cable and ceiling hook not included):
  

• Prix : ~400€ (à confirmer avec le devis demandé par Saliou)
  
• Problème du câble : Utiliser la version Deluxe (sinon on la fait nous même) ?
