I and friends are working to make an inexpensive robot kit named NanoBoardAG now. The target price is under $40. It includes all bricks and devices (motor, controller, etc). NanoBoardAG is based on Arduino and compatible with WeDo and PicoBoard.
I asked Mitch and John (the lead developer of Scratch) and here is how they responded:
Comment from Mitch:
This kit includes a motor and light, and includes a battery box for controlling them. To control these elements from a computer, you would also need the "controller" that comes with the LEGO WeDo kit -- or you can buy this controller (officially known as the LEGO USB Hub) separately (http://www.legoeducation.us/eng/product/lego_usb_hub/1655).
Comment from John:
I assume that the motor could be plugged into a WeDo hub and controlled from Scratch. Scratch doesn't have a block to control the light.
Just FYI.

We hope to bring it to next Scratch@MIT.
P.S. Scratch 1.4 can control LEGO PF Light 8870 by motor blocks with a little modification. Here is a mod that include it. http://squeakland.jp/abee/tmp/SensorBoardWithMotor.zip
