A sensor that measures the turning movement of a wheel for purposes of calculating distance.

Essentially a microphone that returns a voltage proportional to the ambient noise level.

It is essentially a voltage divider and provides an analog voltage corresponding to the angle the knob is rotated to.

It uses mini infrared transmitter/receiver pairs and send signals when the infrared beam is broken by a specifically designed spinning disk

They  are used when high accuracy, or long distances (or both) are required when measuring the range to an object.

A hand tool specifically designed to insert and tighten, or to loosen and remove screws.

It is a device for applying heat to melt solder in attaching two metal parts

It is used in removing soldered wires and components on printed circuit boards for trouble shooting and repair purposes.

It is used for holding, bending, and stretching the lead of electronic component or connecting wires.

It is used to bore or drill holes in the printed circuit board(PCB) with sizes from 1/32” – 1/16”.

It is a pair of opposing blades much like scissors with  the addition of a center notch makes it easier to cut the insulation without cutting the wire.

They are hand tools having a series of sharp, parallel ridges or teeth.

It is a type of brush made of bristles set in handle, used for cleaning dirty parts of a circuit or an object.

It is equipment that combines three functions: that measures both AC and DC voltages; an ohmmeter that measures resistance; and a milliammeter that measures small amount of DC current.

It is is a hard plastic, but when heated (in hot water for instance), it becomes malleable and can be shaped into intricate parts, which then cools and solidifies into durable plastic parts.

It is an electrical machine that converts electrical energy into mechanical energy.

It acts as an interface between the motors and the control circuits.

It is a device or group of devices that serves to govern in some predetermined manner the performance of an electric motor.

It is a brushless DC electric motor that divides a full rotation into a number of equal steps.

It is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration.

It commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field. 

It is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy.

The easiest way to control a vehicle is with a handheld controller physically connected to the vehicle using a cable  (i.e. a tether). Toggle switches, knobs, levers, joysticks and buttons on this controller allow the user to control the vehicle without the need to incorporate complex electronics.

One of the disadvantages of direct wired controller includes there is no worry about loss of signal.

An advantage of ethernet connection is more complex programming being involved.

One of the advantages of infrared is its low cost.
