Stair Climbing Robot
[attachment=60395]
Introduction:
The robot can climb up stairs and obstacle comparable to stair upto
certain height and width depending on the dimensions of the BOT.
Material Used:
Al Rod.
L clamps 8.
Wheels 6.
Screws.
Nylon Strings.
Harddisk Adapter (power supply).
Working Procedure:
Working of the BOT takes place stepwise. There are roughly
four to five steps for the process. The BOT comes to rest momentarilly after each
step. The four steps for climbing the stair are
Lifting the front part.
Lifting the middle part of the bot while moving forward.
Lifting the back part of the bot.
Coming to the initial position.
It is designed in two parts. Both parts are connected by a
clamp by which it can rotate in 270 o. Two wheels are attached to two motos in the
front and two in the back. In the middle part two wheels are attached with out any
motors. In the middle position two motors (one to the front part and one to the back)
are attached (on the body) to its right and one to its left (to the back part) which will
help to lift the front and back parts. Basing on the state of the bot, motors are
operated to lift the bot up the stair.
Lifting the middle part of the bot while moving forward:
After the completion of the first part the
bot comes to a halt for 3 sec. After that second step takes place. The motor connected
in the middle (to the left) starts rotating. The motors shaft is connected to an
aluminium rod. So when ever the motor starts rotating the rod also rotates. After
certain degree of rotation rod hits the ground. As the motors is still rotating the rod
tries to rotate which eventually lifts the middle part. The motors to the back also starts
rotating which will drive the bot to the front.
Programme:
Our basic function is “drive” having two arguments. First
argument is for selecting motor. Second argument is for selecting the direction to
move motor in. There are “5” possible values for first argument and “3” possible
values for second argument.
