This document describes an automatic wall painting robot. It consists of a housing containing a foot pedal and drive shaft that rotate a chain sprocket to power the pump. When the pedal is operated, the chain rotates a freewheel which turns the pump to lift water from underground. The pump can filter water through natural methods. It uses human power from the legs through foot pedaling, rather than arms, to lift water from depths of a few meters. Pedaling provides four times more power than hand-cranking and can pump water continuously for 10-60 minutes, depending on exertion level. The system offers a low-cost manual water pumping option that is simple to operate and maintain while providing exercise for the user

BICYCLE OPERATED WATER PUMP
ABSTRACT
A Water system includes a pedal operated water pump. The pump set and includes a housing in
which a foot pedal and drive shaft rotate in circular direction rotating with the chain sprocket
alignment. When pedal is operated by the operator, chain rotates and due to this small gear
freewheel will rotate, due to this freewheel rotation of the pump will rotate, it pumps the water.
Pumps are a common means of lifting water from a clean ground water source to a useful
point of access, but all pumps have moving parts and are therefore destined to break proper
selection of a pump will reduce undesirable downtime and will empower the local community to
manage their water source.
Here, we are not only pumps the water but it also filter the water by natural filtering
method.
Here we use the foot pedal pump, powered by our legs instead of
arms to lift the water from a depth range of few meters. Throughout history human, energy has
generally been applied through the use of the arms, hands, and back. With minor exceptions, it
was only with the invention of the sliding-seat rowing shell, and particularly of the bicycle, that
legs also began to be considered as a normal means of developing power from human muscles
A person can generate four times more (1/4 horse power (hp)) by pedaling than by hand –

cranking. At the rate of 1/4hp, continuous pedaling can be done for only short periods, about 10
minutes. However, pedaling at half this power (1/8 hp) can be sustained for around 60 minutes.
The main use of pedal power today is still for bicycling at least in the high- power range (75
watts and above of mechanical power). In the lower-power range there are a number of use of
pedal power for agriculture, construction, water pumping, and electrical generation that seem to
be potentially advantages, at least when electrical or internal-combustion engine power is
unavailable or very expensive.
