Eco Robot (E)

E1 Q: What is the definition of actuator? A: Please read from Terms and Definitions section in the Rulebook.

E2 Q: Which electrical components in Eco Robot can be provided from a 24 VDC. Can you explain more details on mechanisms/actuators that can be used in Eco Robot? A: A supplementary definition of Eco Robot is described below: Eco Robot has only one actuator that energy can be pre-stored. This actuator with pre-stored energy must be used only for steering control. Other mechanisms/actuators can be used in Eco Robot if their energies are not pre-stored at the beginning of the game. However after the game starts, these mechanisms/actuators are allowed to store and/or use energy from external or surrounding sources for examples from Hybrid Robot, from game field/structure, etc. External energy can be light, sound, wind, magnetic, and etc.

E4 Q: Can we use Potential energy, spring energy, mainspring energy for Eco Robot ? A: If the potential energy source is used to change Eco Robot direction, the answer is yes with no constraint. However if the potential energy source is used for driving purpose, the energy cannot be pre stored. Eco Robot has to start to store energy after the game has started; for example by receiving energy from Hybrid Robot, from the game field.

E5 Q: Is Wind Turbine Propeller regarded as a part of Eco robot? processing? A: No, Wind Turbine is not a part of Eco Robot.
