| Question | Answer |
|---|---|
| Spot welding | used to join two pieces of sheet metal by passing a high electrical current through a small spot where the two pieces touch. |
| Arc welding | used to join two heavy, solid pieces of metal with the heat from a high-voltage spark. |
| Electrode | consumable metal rod |
| CIM | Computer Integrated Manufacturing |
| Controller | the "brain" of the robot. |
| Teach pendant | a miniature control panel connected directly to the controller with a cable. |
| Dead man's switch | A stop switch that requires the operator to hold it continuously |
| Mechanical Structure | the backbone of the robot. |
| Manipulator | the part of the robot designed to perform the specific task of the robot. It is most commonly in the shape of a multi-jointed arm. |
| Inputs | information sent to the robot through sensors. |
| Outputs | Signals from the controller that instruct the robot to DO something. |
| Brainstorming | The process of creating a pool of ideas for analysis and testing. |
| Analysis | all the ideas generated by brainstorming are reviewed and the most promising ideas are kept for further review. |
| Prototype | In engineering, the first physical model of a design. |
| Optimization | Making modifications to meet all specifications defined in the problem identification stage. |
| Presentation | involves delivery of everything needed to actually build your product. |
| Iterations | A single cycle through a repeating sequence of steps. |
| motor | converts electrical energy into mechanical energy |
| PWM | pulse width modulation |
| gears | transmit motion and force in machines |
| Bearing | component used to reduce friction in a machine |
| Shafts | connecting links between the motors, gears and wheels |
| Radio control | refers to the use of radio signals to remotely control another device. |
| 802.11g | radio control standard VEX robots use |
| electromagnetic waves | created when electrical impulses are sent through the atmosphere at a specific radio frequency. |
| arcade control | you can control the robot’s drive train with one joystick, similar to operating an arcade game. |
| vertical channel | moves the robot forwards and backwards. |
| horizontal channel | rotates the robot left and right. |
