Booth
Able to collect and store solar energy, the outer shell of the hug booth provides power to the control, thermoregulation, emotion sensing, spatial information gathering, spatial information gathering, and sanitary condition monitoring systems. It allows the hugger to be deployed in any area without the need to patch it into a power grid. Attached to a battery, the booth can store power for times when solar input is low.

Skin
Like human skin, it is warm, soft, and inviting. As it is the first layer of contact with the user, the hugger's skin is a high-tech material designed to feel very much like human-skin. It is an essential part of the hugger's human-like look and feel.

Below the skin is a very squeezable substance chosen to inspire embrace of the hugger by the user. Like a jolly, bossomy aunt or grandmother, the hugger gives hugs that are soft and comforting.

The skin has a heating mechanism to ensure it is warm at all times just like a real human body. The skin must either show very little dirt (dark color) or be easily cleaned with soap and water. The sanitary condition monitor keeps an eye on the condition of the skin and phones home when it is need of a cleaning.

Skeleton
Hollow, the skeleton is covered by the heating system, squeezable layer, pressure sensor array, and finally the skin. Inside the skeleton resides the control center, the brains of the operation. Heavy at the base, the skeleton resists tipping over.

Arm
With shoulder, elbow, and wrist joints like the Honda's Asimo robot, they move like a human's arms with similar coordination between the joints and with the appropriate velocity curves. This distinguishes the hugger from a scary, inanimate, lifeless robot whose arms move at constant velocities which would prompt human observers to keep a safe distance.

The hugger is able to accomodate people of various sizes by sensing their height and width. The pressure of the hug is proportional to the amount of pressure applied by the huggee. The pressure sensing network, the cornerstone of the hugger's safety system, is located throughout the arms, chest, and back of the hugger and is a key component in the hugger's responsive human-like nature and attractiveness.

Data from the back determines how hard the huggee is squeezing the hugger. Pressure data from the arms and chest is used to ensure safe operation.

Head
Embedded in the head are two cameras to capture spatial information such as the size of the individual and their facial expression. The size information allows the hugger to properly wrap its arms around the user in a natural human-like manner. Data extracted from the user's facial expressions allows the hugger to react appropriately to the user's mood. A dejected user will receive a comforting "there, there" hand-to-back patting behavior.

Also located in the head is a loudspeaker which gives the hugger the ability to react to the user's mood with exclamations of mirth or sympathy as is appropriate.
