5.2 SELECTED DESIGN -
Design 4 -BAT
DESCRIPTION FOR SELECTED DESIGN -
Optical-flow methods are based on computing estimates of the motion of the image intensities over time in a video.
An airfoil produces a lifting force that acts at right angles to the airstream and a dragging force that acts in the same direction as the airstream.
Halteres used as sensory organs for balance to help stabilise the insect while in flight.
The brain/nervous system uses electrical and chemical means to help all parts of the body to communicate with each other.
UV sensors are used for determining exposure to ultraviolet radiation in environmental settings.
The main sources of electrical power for robots are batteries. The type of battery that is used for a robot varies depending on the safety, life cycle, and weight.
Power actuator is a device that can create movement of a load, or an action requiring a force such as clamping, using an electric motor to create the necessary force.
Power control is a third control mode that can be added to a variety of Spellman supplies to provide another means to control and regulate the output of the supply.
Ocelli (singular Ocellus) are simple photo-receptors (light detecting organs). They consist of a single lens and several sensory cells.
Thorax provides a base for the muscle attachment of the upper extremities, the head and neck, the vertebral column, and the pelvis.
The antennae are a pair of sense organs located near the front of an insect's head capsule.
