BEAM is short for Biology, Electronics, Aesthetics and Mechanics. BEAM robots are made by hobbyists.
BEAM robots can be simple and very suitable for starters.
Biology Robots are often modeled after nature. A lot of BEAM robots look remarkably like insects. Insects are easy to build in mechanical form. Not just the mechanics are in inspiration also the limited behavior can easily be programmed in a limited amount of memory and processing power.
Electronics Like all robots they also contain electronics. Without electronic circuits the engines cannot be controlled. Lots of Beam Robots also use solar power as their main source of energy.
Aesthetics A BEAM Robot should look nice and attractive. BEAM robots have no printed circuits with some parts but an appealing and original appearance.
Mechanics In contrast with expensive big robots BEAM robots are cheap, simple, built out of recycled material and running on solar energy.
BEAM robots are a type of robot that do not use computers. They are typically cheap to make and can be built within a few days unlike computer-based robots that can be costly, complex and take years to build. BEAM robots can be either simple machines consisting of a solar cell, motor, transistors and capacitors or as complex as an 8-jointed, 4-legged walking spider machine. Today we are going to build a Worm Robot.
The robot can crawl like worm.
HOW IT WORKS :
Pulleys and Gear Motor are used to transfe rrotary motion from one place to another.Pulleys are wheels with grooves in the rims, in which a belt or rope can run. Pulleys can transfer rotary motion from one shaft to another.In our Robot a pulley is a wheel driven by a Gear motor. A belt is looped around this wheel and around a second wheel. When the Gear motor is turned on, the powered wheel turns the belt which turns the second wheel and ultimately Rear Wheels attached with the Shaft which drive the Worm Robot in Forward direction.
A slider-crank mechanism is a typical design which converts rotary motion into linear motion. It is achieved by connecting a slider and a crank with a rod. We have connected Part D & F to build Slider – Crank Mechanism. To add this feature,the sliding stroke adjusting screw is placed on top of the rotation shaft center of
the rotation disk (Part F here). The sliding stroke (Part D here) can be adjusted by the adjusting nut locatedon one end of the sliding stroke adjusting screw. Hence slider-crank mechanism which converts rotary motion into linear motion and which turns the Part D i.e. Sliding Stroke and ultimately Front Whee ls which drive the Worm Robot in Forward direction.
