The Spider kit includes over 350 snap together pieces and a centralized brain to bring it to life. Drive the robot manually with a remote control, or choose autonomous drive mode and watch the Spider scurry around all by itself, mimicking real-life movement. This kit is cross-compatible with other VEX Robotics kits. The Spider includes 6 legs, IR distance sensor, LED module and interlocking gears. It walks forward or in reverse while avoiding obstacles, and changes directions by spinning its head 360°. There are 64 different programming variations to choose from. To program, simply flip a series of switches on the robot's brain, allowing for quick experimentation with different modes to determine how it reacts when the sensors are activated. The VEX Robotics Spider kit teaches kids that…

• Motors receive signals from the brain, spinning into action causing the head to rotate and the legs to cycle
• Distance sensor reflects infrared light, which alerts the spider before it crashes into its surroundings
• LED module will change color with every turn of the spider's head
• The brain is the centralized computer that powers the spider, relaying signals from the remote control, and activating the motors and sensors to bring the spider to life

Three AA batteries are required in each Spider and one 9V battery is required in each remote. Batteries not included.
