The machine, excluding the remote control, must fit within a box of dimensions 30cm X 30cm X 40cm at the start of the game.
In case of using electric energy for propulsion and drive, the potential at any point on the machine should not exceed 12V. Use of air compressors 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 machine has to be necessarily controlled by a wireless remote control system. The participants have to bring 2 remote controls of distinct frequencies or a dual-frequency remote control, which can be switched to either frequency just before the start of the run. This is done to avoid frequency interference with competing machines.
