The machine must fit within a box of dimensions 30 cm X 30 cm X 30 cm at the beginning of the game. Refer to arena diagram for more clarifications on starting zone. The machine, when put in the arena at the start of the game should have the same size as checked with the dimension box above.
The external wired remote control used to control the machine manually is not included in this size constraint.
In case of an electric power supply, the voltage at any point on the machine must be lower than or equal to 12V at any point of time during the game
During the game, the machine can expand or detach itself into multiple parts provided it does not damage the arena in any way. The judges hold the right to subjectively determine if the machine violates this clause.
Machine cannot be constructed using ready made Lego kits or any ready made mechanism. But you can make use of ready made gear assemblies. Violating this clause will lead to the disqualification of the machine.
The machine can use an externally placed or on-board electric or non-electric power supply. Use of compressors is not allowed. Use of compressed gas is not allowed. However the power supply must be non-polluting and must satisfy the safety constraints determined by the judges. In case the machine is using a non-electric power supply, kindly get it approved from the organizers beforehand via email. Organizers are not responsible for inconvenience if approval is not sought.
The method of working of the machine is at the discretion of the builder, provided it does not damage the arena in any way and it satisfies the safety constraints determined by the judges. The machine (or any of its parts) cannot use any mechanism which directly transmits manual force to the machine (or any of its parts). For example use of clutch wires is not permitted. The judges hold the right to subjectively determine if the machine violates this. That also means that the electric wires joining the control panel and the machine should be slack at all points in time of the performance of a team.
In case of an electric power supply, the voltage at any point on the machine must be lower than or equal to 12V at any point of time during the game.
The organizers will provide a standard 230V/50 Hz AC power supply. Any extension cords, eliminators, adapters etc required will have to be arranged by participants themselves.
The machine has to be necessarily controlled by some wired remote control mechanism at all stages of the game. More than one team members can control the machine at a time, more than one control mechanisms can be used.
