Good beginner robotics project?

[BOOM! HEADSHOT]

Hey guys I'm looking for a good basic robotics tutorial for beginners, I have a Raspberry Pi B+ and I know Python basics and some advanced stuff. I would love to do something with autonomy. If you guys could recommend a beginner tutorial with a part list (not over 100$ please), that would be great.

Have a look through http://www.themagpi.com/ and see if anything there suits.

I'm guessing BMS Doug will be along in a minute. He's got his Raspberry Pi powered Dalek.

I tried searching for ''robots'' and ''robotics'' but I only found the Skutter which looks like a pretty advanced project. Any other recommendations.

A cheap setup:

- Magician 2WD chassis
- L9110S driver board
- prototyping board to help with connections
- 4xAA batteries for the motor
- usb power bank for the Pi

joan's pigpio library is excellent for inexpensive Pi bots

sorry to disappoint, I was tired at the weekend. (kids party Saturday, Sunday was recovery)

My Dalek has a long way to go before it will be an autonomous robot, I'm just aiming for remote control first. (honestly getting remote control working is a good first step, you can then add autonomous functions when you are ready)

As with Bill, I would recommend getting a Magician Chassis and a motor driver board (I have no experience of the L9110S driver board, I use a L298N but either will probably be fine).

Having wheels and a chassis is a start, but you need power and a method to communicate, you may consider a WIFI dongle although I have had good experiences with powering the pi from a WIFI router powerbank which you could connect to with a network cable. You would still need a separate battery for the motors.

Once you have a working WIFI controlled machine you need to convert it to be autonomous, you then need sensors of various kinds, perhaps the first step would be proximity (you could issue a command to drive until it reaches a wall, then turn around and come back).
Proximity detection can be handled in a number of ways: Ultrasonic, IR reflection, contact probes, visual recognition...
