Randomly turn right or left by 90 degrees and walk in that direction for 5 seconds.

Currently scarab performs 3 different dances, which he chooses randomly in front of each obstacle: Some of the dance moves are just for fun and show-off.

A dance is a sequence of movements Scarab performs to help it decide how to go around an obstacle. When scarab detects an obstacle, it performs a ' dance'. (A black teddy-bear is still somewhat a challenge for this Scarab.)

IR sensor does not detect black objects.

Ultrasound sensor does not detect soft objects (e.g., a teddy bear).

The decision to have two sensors for obstacle detection comes from the fact that each of the sensors have its limitations:

Since Scarab has Arduino Nano on board, it could be programmed to performed variety of actions, including serving as a physical platform for executing programmable steps in the equivalent of the Logo programming language.

Flash LEDs, point the direction with a laser beam.

Detect being upside-down or on the side.

The robot should be able to do a lot of things.

The Idea: To build a programmable robotic spider based on Hexbug Scarab, equipped with the following sensor suite:
