5 Servomotor Robotic Arm Kit
$349.00
Teaches Basic Robotic Principles -- Using this kit, you can build a 10"-high robotic arm! One of the components you will make is a 5-position servomotor controller (soldering required) that will allow the robot to manually grab, lift, lower, wrist rotate and pivot. -- The robot is capable of 180-degree base rotation,180-degree shoulder-moving range, 180-degree elbow-moving range,180-degree wrist rotation range, 32mm (1.25") gripper open and 3.0 oz lifting capacity. -- Windows (98/XP) control software (included) lets you control the robotic arm's movement through your PC. The software has a scriptwriting feature that allows you to program the robotic arm with thousands of movements with full, precise and repeatable control of each movement. Scripts may hold a maximum of 10,000 movements (including pauses) with a maximum repetition of 10,000. -- Kit includes: 5 Servomotors, Servomotor brackets, robotic arm base, Servomotor gripper, Servomotor controller kit, instruction manual and CD with Windows programs.

Attack Wave Pestrepeller
$29.95
Keep Pests Away Without Any Spray -- An electronic solution to pest control, the Attack Wave Pestrepeller-¬ is an effective, user friendly and environmentally safe way to combat rodents. The device produces strong sound pressure in the air, attacking the auditory and nervous systems of rodents causing them to abandon their food sources and shelters. -- The ultrasonic sounds continuously penetrate up to 5,000 unobstructed square feet. This is a permanent solution, as pests will not become immune to the sound, because the unit utilizes automatic wave variation. Inaudible and harmless to humans and common pets*, it totally chemical and battery free. -- *Note: Do not use in the presence of Gerbils, Hamsters, Guinea Pigs, and other rodent pets.
