Electric Vehicle

(section: 2 / paragraph: b,c,d / sub-paragraph: n/a / line: 4,6-11)

2016-03-02 22:20 Is it legal for one battery to provide all electrical energy to the motors, but another to power an aurdino, controlling an array of electronics, including motor shields and relays, switching main power on & off from the battery pack to the motors?


(section: 2 / paragraph: c,e / line: 1)

2016-03-02 21:50 Can a step up transformer be used to increase the voltage from 7.2v battery so that it will run a 12V motor?

Yes, this would be allowed.

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

2016-01-18 11:20 The rules state that additional energy storage devices may be used to operate other functions provided they don't help propel the vehicle. Would additional energy storage devices be allowed for a microprocessor (ex. Arduino) that controls the motor?

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 14:15 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 20:58 The rules say any electronic components are allowed, does this include encoders?

Yes, encoders are allowed.

(section: 4 / line: para.4)

2015-11-12 14:26 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: a / line: 2)

2016-01-18 11:12 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: 1)

2016-02-20 13:11 Are competitors allowed to walk behind target to instruct their partner in aiming their vehicle?

Yes, but they must be behind the start line during each run.

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

2015-10-09 18:37 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.
