Preliminary Design of a Robot :: Robotics

Preliminary formulateThough my prototype serves the corresponding function as the production version ordain, theproduction version provide visually be a totally different golem. While interrogation my automaton, I identifiednumerous problems the design of my prototype that could not well buzz off been fixed. To fixthese problems, completely new materials will be essential as well. Since it is alikely that myrobot would be used by alter people(most probably with poor motor control), it is necessarythat the robot is durable, and safe to use. The outer(prenominal) shell will be made out of aluminum, since itis a relatively light and cheap metal. It is important that the robot weighs as little as possible, soit does not require large motors, which will increase the comprise and overall size of the robot. Sincealuminum often has sharp edges, the robot will be covered in padding to reduce the risk of disfigurementfrom operation, and act as a shock absorber if the robot is s truck by an object or dropped.The other(a), more obvious difference will be that the real version of my robot willbe controlled by a circuit board, instead of an RCX control brick. This will allow the use of many another(prenominal) different sensors and motors, and surprisingly will likewise be considerably cheaper. The otherimportant difference is that the real version of my robot will hold open using a robotic arm instead ofmoving as whole. However, the robot will still be able to move for convenience. Just like theRCX, it will have computer connectivity, except that it will have a wired connection for higherspeed and lower cost.Materials and Prototype DesignParts ListMany standard Lego parts3 Motors8, 16, 24, and 40-tooth gears peerless Touch Sensor1 RCX1 Black Crayola MarkerMy robot is divided into 3 basic parts (not including the RCX brick). Below the RCX,brick, I have the standard wheel structure with the standard gear configuration. There ar eighttoothgears on both motor s, connected to the wheels with forty-tooth gears for maximum torque.I have also used the standard medium-sized, flat tires in the front since they perform well.However, thither are no rear wheels Instead, the back of my robot is supported by bare forty-toothgears, which has caused no problems. The reason why I have this unrivalled wheel setup is because Ioriginally built legs for my robot, but switched to wheels later on finding that the legs hadextremely little traction.The second, and most complicated part of my robot is the marker-lowering mechanism.This mechanism is comprised of a motor, a very large set of gears, and a platform that slides on
