GeoLogic Mapping

(section: 2 / paragraph: b / line: 3)

2016-01-16 19:24 The parameters call for a geologic compass and I'm just trying to clarify what is meant by geologic compass. Transit compass or bearing compass for maps?

Any compass that allows to take strike, dip, plunge, and trend measurements will be good. Therefore, students need a compass that, on top of indicating the magnetic North, also has a clinometer and allows sighting distant landmarks.

(section: 4 / paragraph: e / line: 1)

2016-01-16 19:25 Using a geologic compass is new this year. There is a wide range of models and prices. What is recommended?

All Silva compasses in the "Ranger" series provide a cheaper and good alternative to the much more expensive Brunton compass.

2015-10-12 19:36 If the bridge is loaded not to failure of the bridge, but rather the test support falls over, how will the bridge be scored (will there be a second try) ?

If the test support falls over, loading will stop and the weight held at that time will be used to calculate the final score. There will not be a second try at testing the bridge.

Electric Vehicle

(section: 2 / paragraph: d / line: 1)

2016-01-18 10:20 In the rules it states that any additional energy storage devices may be used to operate other functions provided they don't help propel the vehicle in any way. So would an additional energy storage device be alright to use for a microprocessor th...

Batteries used for non-propulsion purposes would not count toward the maximum number of batteries in 2.c. Anything contributing to controlling the motor would be considered to be contributing to propulsion.

(section: 2 / paragraph: d / line: 2)

2015-11-12 13:15 Can the motor controls contain capacitors (energy storage devices) that are verifiably fully discharged at ready-to run ?

Yes, as long as the capacitors are discharged before the run and any electrical power in the capacitor after the discharge comes from the allowed batteries/cells, then they are allowed.

(section: 2 / paragraph: e / line: 2)

2015-11-12 19:58 The rules say any electronic components are allowed, does this include encoders?

Yes, encoders are allowed.

(section: 4 / line: para.4)

(section: 4 / paragraph: a / line: 2)

2016-01-18 10:12 May a computer be used as a tool?

Yes, provided the computer only connects to the vehicle between runs and not during the run, it is considered a tool.

(section: 4 / paragraph: h / line: 19)

2015-10-09 17:37 Does the restriction on sighting, aiming, and guiding devices mean that we can't use a laser pointer to guide our device DURING THE RUN? (rather than, right before we start).

Yes, laser pointers are always to be controlled by human operators (see the general SO policy on lasers at https://www.soinc.org/lasers ) and the vehicle must run autonomously, so laser pointers must not be used during a run.
