Q: Regarding Inclined Planes it States "Raised vertically at least 10.0 cm". Does that mean raised 90 degrees from the ground or just 10.0 cm in an upward direction along the Inclined Plane? (section: 4 / paragraph: d / sub-paragraph: iii / line: 2)

A: An inclined plane must be used to raise an object at least 10.0 cm vertically. The vertical distance is measured at a 90 degree angle and must be at least 10.0 cm. The object does not have to travel at a 90 degree angle but overall must rise 10.0 cm vertically above where it started before the object initiates the next action.

Q: States "lift an object at least 10.0 cm vertically". Does that mean it must be lifted at 90 degrees from the starting point or just moved in an upwards angle at least 10.0 cms? (section: 4 / paragraph: d / sub-paragraph: ii / line: 1)

A: The pulley must lift an object at least 10.0 cm. The vertical distance is measured at a 90 degree angle and must be at least 10.0 cm. The object does not have to travel at a 90 degree angle but overall must rise 10.0 cm vertically above where it started before the object initiates the next action.

Q: The rules say that Brushless motors and integrated circuits are not permitted, does this just refer to integrated circuits to control motors or things like adjustable voltage regulators and arduinos. (section: 4 / paragraph: i / sub-paragraph:  / line: 1)

A: Note there is an official rules clarification related to this, available at: https://www.soinc.org/official_rules_clarif The integrated circuit prohibition refers to all components (including voltage regulators / arduinos) other than those specified in the rules clarification.
