ABSTRACT
The purpose of this research is to
implement hydraulics system and solar energy in
The Tennis Balls Collecting Machine. The machine
is operated with power of motor from solar cell
energy. The canvas conveying belt is connected to
the motor for carrying tennis balls to the basket.
Hydraulics system lifts a tennis ball basket for
releasing tennis balls to tennis ball keeping basket.
The capacity of machine for containing a ball is
between 120 to 140 balls and the ability of picking a
ball is at the rate of 80 balls per minute depending
on the perimeter distance of spread balls. The result
of the test of machine operating without solar cell
showed that the machine can be operated for 4
hours continuously. In addition to, 4 hour; it can be
used with charging battery from electricity. When it
is connected a solar cell to the machine, it can be
operated uninterruptedly and it is continuously
charged by solar cell. In addition, the result of the
ergonomics posture assessment tests: Rapid Upper
Limb Assessment (RULA) showed that the height
and path length of handle are suitable for user.
