Could you tell me about some robots kits helpful in robotics?

Streak is the outdoor robot with around 4 High Torque DC Geared motors and some high quality 10 CM wheels. The robot has one payload capacity of about 7 KG weight on the flat surfaces and up to around 3 KG on rough terrain. The robot is just controlled through Rhino Robot controller board which is very much powered by AVR Atmega16A microcontroller, its completely expandable and it can be connected to multiple boards and the sensors with ease. The board even comes with the USB boot loader so that it can even be programmed through the PC easily. The kit just also includes one carry plate for Laptop and around 3 Sharp IR or the Ultrasonic sensors (sensors optional). Any type of standard laptop can be easily strapped over this robot. The laptop can even communicate with robot board through your USB port and program/control the robot.
