This robot flies around in high trees, expertly harvesting fruits and nuts

Operation

Sensors and actuators
To fly between plantations and drop-off areas it uses its main propulsion; two electrically driven directional thrusters, jetting out
blue beams underneath. For finer navigation around trees it directs the attached propeller by tilting its head.
Apart from its main visual sensors, two brown-orange compound 'eyes' based on those of arthropods, it also has blue proximity sensors in all horizontal directions. It also features lamps color-coded similar to common vehicles for nearby humans to recognize its side and front; orange lights on the sides, red lights on the back.
Fruits and/or nuts are picked by the two telescopic grip arms and stored in a lower compartment inside its torso.

Energy and ethics
Battery cells stacks in its upper torso provide energy for its operation.
These are rechargeable either by the solar panels on its back and shoulders, or by plugging in the cord tied around its neck.
The power cord is striped yellow-black stripe to alert any nearby birds or other critters.
Should animals be within a certain distance, the droid will immediately hang from the nearest branch with its grip claws and power down until the animal has left the hazardous proximity zone. Its programming is an attempt to extend Asimov's three laws of robotics. The extended version could be stated as follows:

1. It may not injure a human or animal being, or through inaction, allow a human or animal being come to harm
   
   
2. It must obey the orders given it, except where such orders would conflict with the first law
   
   
3. It only protects its own existence as long as such protection does not conflict with the first or second laws
