Chapter 8 Flashcards
What is an industrial robot
an auto controlled reprogram-able multipurpose m,manipulator in 3 or more axes
First application of an industrial robot
unloading at car manufactring plant
5 joint types for a mainpulator
- linear
- orthogonal
- Rotational
- Twisting
- Revolving
What is work volume
3d space within which the robot arm manipulator wrist can move
What is an end effector
device at the end of the manip wrist which is task related
Advantage of dual gripepr of single gripper
reduces the amount that maniltur must move per cycle
What are general charistics of work situations promotoe automation
- HAzardous wokr for humans
- Reptitive work cucle
- Diffuclt handling
- Multishift operation
- Infrequent change over
- PArt posiiton are established in work cell
3 categories of industrial robot applications
1,Leadthrough programming
- Comoputer like robot programming languages
- offline programming
What is the difference between powered lead through and manual lead-through in robot programming
Powered lead through is use for robots with point to point control, involving toggle switches and or toggles to power drive the robot arm to a desired position and the position and sequence is stored ion memory and the robot will then do it on its own
Manual lead through is used for irregular patterns, the operator must physically grasp the robot and walk it through its irregular sequence and then it is recorded in memory
What is the difference between repeatability and accuracy in a robotic manipuklator
Repeat ability is a robot’s ability to position end of wrist at a PREVIOUSLY taught point in the work volume. Like when a robot resets for next cycle
Accuracy is the robots ability to position the end of its wrist at a desiired at a desired location in a work voume
