Servo robot driver

Over the past few years, robotics and cybernetics have become new fields of interest for many an owner of a personal micro, equipped with the necessary add-on boards to effect peripheral control. However easy it may seem to write robot control pro- grams and to build the associated computer hardware, the construction of accurately operating mechanical parts (or, if you like, limbs) often poses unsurmountable problems, since a miniature set of gears, ball bearings, spindles and cog-wheels are in no way readily made items for those skilled in programming and soldering. Despite their limitations as to pre- cision of movement, servo-motors 4,8V 1mA (3...15V) servo-robot driver 131 20 ms 1-2ms 1 1213141 86487-1 2 3 4 EE 30 July/August 1986 used in model aircraft or boat con- struction may offer an interesting alternative to more complicated mechanical constructions; appli- cations such as robot arms and sort- ing machines can be made quite easily with the use of cleverly mounted serv...
