Preliminary Design of a Robot :: Robotics

Preliminary normalThough my prototype serves the same function as the production interlingual rendition lead, theproduction magnetic variation depart visually be a tout ensemble different zombi. While testing my robot, I identifiednumerous problems the build of my prototype that could not easily have been fixed. To fixthese problems, completely hot materials will be required as well. Since it is likely that myrobot would be used by dis able-bodiedd people( nearly probably with poor motor control), it is needfulthat the robot is durable, and safe to use. The outer shell will be do 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 great motors, which will increase the cost and overall size of the robot. Sincealuminum oftentimes has sharp edges, the robot will be covered in hyperbolise to reduce the risk of injuryfrom operation, and act as a wound absorber if the robot is stru ck by an object or dropped.The other, more translucent difference will be that the real version of my robot willbe controlled by a circuit board, rather of an RCX control brick. This will allow the use ofmany different sensors and motors, and surprisingly will too be considerably cheaper. The otherimportant difference is that the real version of my robot will write 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, draw out that it will have a wired connection for higher belt along and lower cost.Materials and Prototype DesignParts ListMany stock Lego part3 Motors8, 16, 24, and 40-tooth gearsOne 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 well-worn wheel structure with the standard gear configuration. There are eighttoothgears on both motors, connected to the wheels wit h forty-tooth gears for upper limit torque.I have also used the standard medium-sized, flat tires in the front since they perform well.However, there are no rear wheels Instead, the acantha of my robot is supported by bare forty-toothgears, which has caused no problems. The reason why I have this odd wheel setup is because I in the beginning built legs for my robot, but switched to wheels after 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(prenominal) large set of gears, and a platform that slides on
