Conclusions<br />
<strong>system</strong>, parameter adjustments need to be replaced by a more <strong>system</strong>atic<br />
method.<br />
The sensors utilised during the tests are intended <strong>for</strong> industrial detection.<br />
However, it needs to be confirmed that intensive application in hard on the field<br />
conditions will not cause any negative influence on their robust work. The digital<br />
RGB fibre optic sensor CZ-H35S uses a light emitter with a spot diameter <strong>of</strong> 4.5<br />
mm. Parallel implementation <strong>of</strong> several sensors covering an area at least as<br />
wide as the laser sensor is required <strong>for</strong> reliable detection.<br />
The developed prototype <strong>for</strong> intra-row <strong>weed</strong> control could be used in future <strong>for</strong><br />
accurate measurement <strong>of</strong> the torque. The potentials <strong>for</strong> optimisation <strong>of</strong> the<br />
torque are highly influenced by the size and shape <strong>of</strong> the duckfoot knives. Their<br />
behaviour in different conditions needs to be investigated. Change <strong>of</strong> the soil<br />
moisture content, change <strong>of</strong> the hoeing speed, change <strong>of</strong> the <strong>for</strong>ward speed,<br />
change <strong>of</strong> the hoeing depth are only several aspects which can deliver new<br />
substantial knowledge very important <strong>for</strong> further development <strong>of</strong> the <strong>mechanical</strong><br />
intra-row <strong>weed</strong> control.<br />
A possibility <strong>for</strong> improvement <strong>of</strong> the controlling algorithm will be substitution <strong>of</strong><br />
the currently used P with PI, PID or another more sophisticated one, like a fuzzy<br />
or neural network based algorithm.<br />
Finally, testing <strong>of</strong> the intra-row <strong>weed</strong>ing <strong>system</strong> combined with an inter-row<br />
<strong>system</strong> in field condition will be <strong>of</strong> great importance.<br />
