RoboLawnMower

Brush cut robot
Use a brush cutter driven with a hydrogen fuel cell. The hydrogen is made with sun power. As the brush is cleared a wild type of grass is planted around the trees opening up natural bush for free animal roaming and increasing its water absorption ability.


 * Use a machine under operator video control to cut brush.

RoboTics have advanced to the stage where manual labor like orange and grape harvesting is automated.

asdf
Connect RS485 nodes around a perimeter and install InfraRedLeds forming a matrix of beams which together with RateGyro2 will help orient the lawnmower.

Automated grass cutting around macadamia trees
Install a guide wire around the base of the tree in a circle so that extends by 3cm around the tree. Place the metal detector sensor in the nose at the front of a custom robotic lawnmower that is powered by battery. This prevents the lawnmower from colliding with the tree.

Controlling weeds in plantations
Build a sturdy four wheel based.robot. Attach a rod on a 3D-swivel point so it can move from side to side. At the end point attach an electric motor directly to a cutting blade. Walk behind it while steering using RC control.

Four wheel robot
Build four wheel robot with blade in middle that can slide from left to right. The robot moves in a straight line in the plantation between the banana trees in the line that has no banana leaves. Banana leaves are cut so that only one line has a mulch. Place multiple ultrasonic sensors 50cm in front of the blade that maps out the contour to determine the minimum distance the blade can be from the ground.

Place guard ring around blade
Place a guard ring around the cutting blade. Place multiple contact bump switches around the guard ring to detect when colliding with ground.

Bluetooth
Attach two BlueTooth modules to either leg of the human operator. As he walks forward the the BlueTooth module automatically steers the robot forward. The operator can move the cutting head from in three dimensions.

Contact switch
If the robot though does bump with the tree a contact switch is pressed cutting the power to the motors and alerting the farmer for further inspection.
