Our team had participated in IIT Shastra 2006 held
at IIT Chennai during 4th October to 8th October. We had participated
for the event ‘Stair climber’.
Problem statement:
Design a machine which can climb 10 steps each 10 cm high and 1 m width using a
robot. The robot was to fit in a box of 30X30X30 cm initially.
Construction:
The Machine had in all 12 wheels in which 4 were
driven by the motors. Thus there were 4 driver wheels, 4 driven wheels, and 4 idler
wheels. A pair of driver wheels and driven wheels was coupled using a v- belt. Hence,
in total we had 4 pairs. The machine was divided in 2 parts. One part was the base
of the machine on which the battery was mounted. The base of the machine was made
of wood while the pairs of wheels were held by the MS plates of 1mm thickness to
keep the distance between the driver and driven wheels constant. The second part
of the machine was a replica of base held inclined with the base at the angle of
40°.
The angle was calculated by drawing a sketch. The inclined part and the lower part
were hinged together by a common shaft (MS rod). The arrangement of both parts was
such that the common shaft held the 4 driven wheels. The length and the width of
the base was 30X30 cm and the length and the width of upper inclined part was 30X26
cm. Initially both the parts were fixed in 30X30X30 cm. After the competition started
the inclined part was opened giving a jerk and was locked using slots.
In between the 4 pairs idler wheels were fixed on
the MS plate. The two opposite pairs were coupled using the shaft. The idler wheels
avoided the bending of the belt during climbing the stair. The advantage in this
design was that during climbing the corner of the stair applied less reaction on
the inclined part of the machine thus reducing the effort to climb the stair. Also
as high torque motors were used the climbing speed was high.
