Motivation for an autonomous milking ongoing robot (AMOR)
An autonomous system results in the following dis-/advantages:
- + Indepence (no more need to be there to milk morning and evening, 7days/week)
- - Machine service increases
- + Technical knowledge increases, hence perhaps some other good robot ideas may evolve.
- + Cows/Goats/Sheep can decide themselves when to get milked.
- + Concentrated feed can be delivered automatically and according to milk delivered.
- - Animals' possible illness not realized early enough. => Action taken too late. => Animal could die.
- - Gathering at Milking robot leaves behind a lot of unusable muddy terrain at entrance (doors in general).
- - Higher complexity in separation of milk for calves, though of course possible.
- + Driving out and in of cattle no longer necessary as animals can get milked outside.
- ... and several others.
An ongoing system results in the following (dis-)advantages:
- - Higher complexity.
- + Independance of any external supplies.
** Water (difficult) ** Power ** Food (difficult)
- - Redundancy of susceptible subsystems (Electronics, in general: The more complex the system the higher the vulnerability).
- + Less cabling, water pipe laying and bundled maintenance (as you can wait for enough minor errors to accumulate before taking the system apart).
- ... and several others.
Separation in Subproblems & Technological Difficulties
Our AMOR consists of several submodules:
- MECHANICAL CONSTRUCTION
- - Difficult to be robust, lightweight (for truck to lift) & cheap the same time.
- + Rain serves as a water supply and natural (ecologic) washing.
- VACUUM SYSTEM
- - Difficult to be flexible in frequency (provide user settings) and keep it simple at the same time.
- + Could be used for several other functionality than milking (doors, ...). => No hydraulics needed.
- Note: As the robotic manipulator should be flexible anyway, compressible air/vacuum could serve this purpose, too - stays the problem of vulnerability to leakage.
- Vacuum pumps.
- STORAGE CONSTRUCTION
- Milk
- Food
- Water
- Energy
- Database for animals milk (amount, properties, ...)
- Database for organization of the cow's fertile cycle, ...
- SENSORICS
- Milk properties (flow rate, derivations of that, TODO)
- Robotic manipulator (3D camera, washing mechanism)
- Animal within milking construction => Door states.
- ELECTRONICS
- Control of Doors.
- Control of Feeding (derived from amount of milk), but also accept some user constraints (lower / upper bounds for each type of food respectively).
- Control of Robotic manipulator (joints, gripper).
- Collection & storage of the stored animal & product data.
- SOFTWARE
- Microcontroller programs capable of controlling at least two AMOR system blocks (stacked next to each other).
- compare ELECTRONICS.
