Only $72.95 Or Browse other spider Supplies "Cool" just got even cooler with the invention of SPIDER III, the third generation in a quest to offer the most advanced design and technology available. With its radical walking style, this intelligent robot avoids interference. Basic hand tools and soldering are required for assembly. When assembled, SPIDER III emits a light sensor beam; detects obstacles in its path, signaling it to change direction and continue on a new path. A bat flies in the dark sensing its own super-sonic wave reflecting back from obstacles. Likewise, SPIDER III emits light sensor rays and judges by the reflection if there are any obstacles in front and gives signals in the form of electric pulses to alter the rotating direction of the left side motor to evade obstacles. Requires two "AA" batteries (not included). This kit requires a more challenging soldering of the circuit boards and mechanical assembly.
