Bridge Building - Div C

(section: 3 / paragraph: e / sub-paragraph: N/A / line: N/A)

2015-10-29 13:14 Does this mean that the loading block shall be aligned with the centerline of the test base, or is it acceptable for the loading block location to be off to one side as long as it allows for the chain pass through the 20cmx20cm opening of the test?

The loading block is to be aligned with the centerline of the test base which would be the center of the Bridge span when it is placed on the Test Support on one side and the Bearing Zone of the Test Base on the other side.

(section: 4 / paragraph: c / sub-paragraph: i / line: 1)

2015-10-29 13:24 Will the 5 by 5 block be secured to the testing apparatus?

No, the 2 cm x 5 cm x 5 cm block will not be secured to the Test Base.

(section: 5 / paragraph: b / sub-paragraph: i / line: 1)

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: 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)

2015-11-12 13:26 Can the vehicle stop (not a "complete stop"), but then go backwards or forwards slowly to get the dowel on to the target point between 9 and 12 meters?


(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 ) and the vehicle must run autonomously, so laser pointers must not be used during a run.
