Scrambler
Teams design, build, and test a mechanical device, which uses the energy from a falling mass to transport an egg along a straight track as quickly as possible and stop as close to the center of a Terminal Barrier (TB) without breaking the egg.

Rule 3.c. - During setup, time will be paused so students can demonstrate their mass falling without the vehicle attached. If the mass contacts the venue floor or has the potential to damage it, a construction penalty will be assessed per rule 3.c. and students will be required to launch using a VASO-provided cushion.

Rule 3.c. - The protective pad/cushion referenced in this rule is considered part of the device and must fit within the allowed Scrambler device dimensions. VASO expects it to actually protect the venue's floor from damage, not just prevent the mass from contacting the floor.

Rule 3.e. - ...The egg backstop must be built of any rigid material, and it must have a flat surface of 5.0±0.5 cm wide by 5.0±0.5 cm high by 1.27 cm (0.50”) thick 1.1 cm or thicker.

Rule 3.a. - Teams, even if they are from the same school, may NOT share an energy propulsion system (launcher) in VASO tournaments.

Rule 3.f. - Since dowels sold as “¼ inch dowels” are typically slightly narrower than that, VASO will accept dowels that measure approximately ¼ inch.

Rule 3.g. - Event Supervisors at VASO tournaments will not allow the egg to be placed inside a bag.

Add a rule 4.b.iv. - If a kit was used to build the team’s device, the Design Log must also include an explanation of at least one substantial modification made to the kit as required by the Constructed Devices Policy.
October 5, 2022
Rule 4.e. - Logs will not necessarily be returned to teams. Teams should keep their original log and submit a copy to the Event Supervisor.
