You can scavenge robot parts via faulty,damage,broken,dead electronic devices that people may consider trash. The parts that you are mosly interested are listed as follows:
Gear motors are GOLD or very useful in robot building. The best gear motors are made by Micro-Mo,Maxon,Mabuchi,Nihon and Namiki (to name a few).
- Motors - DC motors, Stepper Motors but very rare AC Motors (not very common in building a small robots), vibrating Motors( Mobile phone or pager)
- Switches - micro switches, ON/OFF switches,Flip switches..
- Capacitors - Electrolytic, monolithic, tantalum capacitors.
- diodes
- resistors
- integrated circuits - 555 timers,PN2222,2N3904,PN2907,...etc
- Pinch rollers, pulleys, gears,belts,..
- Metal rods ( toner catridges), Plastic Sheets.
- Gear headmotors - mechnaisms that move slowly.

TIPS:
- Never expose an IC to more than 6 Volts, unless you're darn sure it can handle it. This means no hooking your circuit up to 9 Volt battery without a way of reducing the voltage!
- Never sit on an IC especially if it's pins up otherwise you will have a nasty jump which leave a very embarrasing set of bite marks. Those pins are quite sharp. Every now and then the pins manage to poke into my finger if Im not careful.
