Well, the answer depends on the robot. If your robot comes as a kit, you might not need any additional tools at all, or only those supplied with the kit (such as an Allen wrench or a Phillips head screwdriver). If you're building your own bespoke robot you may need to construct your own chassis or hardware components, or ask someone with tools and experience to help you.

If you're building your own bespoke robot you may need to construct your own chassis or hardware components, or ask someone with tools and experience to help you. It's important to learn how to use both hand and power tools properly — they can be quite dangerous if you don't know what you're doing or if you don't use sensible practices such as clamping your materials properly before drilling or cutting (I have a few scars to prove it).

!! Some Tool Advice
''Buy as good a quality as you can afford'':   good tools can last your lifetime if you take care of them (don't leave them somewhere they'll rust). I have a pair of scissors from 1978 and they're still sharp. My pliers and cutters are still like new and I use them a lot.

It's important to learn how to use both hand and power tools properly — they can be quite dangerous if you don't know what you're doing or if you don't use sensible practices such as clamping your materials properly before drilling or cutting (I have a few scars to prove it). Here's some safety tips:
* __Buy as good a quality tools as you can afford__:   good tools can last your lifetime if you take care of them (don't leave them somewhere they'll rust). I have a pair of scissors from 1978 and they're still sharp. My pliers and cutters are still like new and I use them a lot. I take good care of my power tools and they are like new after many years' use.
* __Take care of your tools__, and only use a tool for its intended purpose. Using a screwdriver as an awl to poke a hole or pry open a container is a good way to poke a hole through your hand, ruin the screwdriver, or ruin the thing you're opening
* __Store your tools in appropriate containers__ (like toolboxes or the cases they came in) to protect them from dust and moisture (and insects and mice too). Don't allow sharp edges of tools to bang together or even touch when stored, wrap them as necessary in some spare cotton or wool fabric. In fact, if you can help it, don't let different kinds of metals touch during storage, as this can sometimes create a chemical effect that can invite rust.
* Steel parts like drill bits don't mind being __bathed in light oil__ when they're not being used. Or you can store them in an oily rag. You just pull them out of the oil and wipe it off before use. Drill bits stored in oil will last a long time.
* __Keep your tool edges sharp__ using appropriate sharpening tools and techniques.
* __Clamp stuff down__ before operating on it. A block of plastic that gets caught in a drill bit quickly becomes a very dangerous weapon!
* If something you're doing seems like a bad idea, __don't do it__. A mistake can be costly.
* And lastly, __wear proper eye, ear, and hand protection__, i.e., %%grn follow proper safety precautions%%. It's pretty hard to fix your eye after a piece of metal has flown into it.
As an illustration of that last point, a few years' back I was hand-sanding some metal part and a tiny piece flew into my eye (I was wearing eyeglasses but not protective eyewear), and after about an hour of desperately trying to flush it out with water in the bathroom sink (I was starting to really panic as it seemed pretty stuck) ended up having a doctor at the local hospital's emergency ward fish it out in a couple of seconds. Really nice young guy. ''I don't want to see him again.''
I'm lucky it wasn't a bigger piece and that there was no lasting damage.

* good quality __straight ruler__. A stainless steel metric ruler should last a lifetime; I've had mine for over 30 years

* small __hacksaw__ for cutting plastic or aluminum/aluminium (a power tool works too, but sometimes a hand tool is slower, safer, and more accurate)
* __hand clamps__ or a __bench clamp__, to hold things while you're working on them. I find the blue and yellow ''Irwin Quick-Grips'' pretty handy and come in many sizes

* __power drill__ is probably the most important power tool, as almost everything else can be done by hand. Yes, you can use a hand drill but you have to hold it much more carefully, for longer, as you rotate the handle. Wobbly use can make a poor hole, and with small drills even break the bit. A drill press is nice but not really necessary.
* __power jig saw__ is handy but not essential. Likewise, a table saw is handy but kinda overkill for most of the cutting you'll do.

This is not to say that if you already have a whole shop full of power tools you shouldn't use them. It's just that building a small robot doesn't ''require'' that. [David Anderson], who built the [SR04] robot, has an entire [home machine shop|http://www.geology.smu.edu/dpa-www/metal/index.html] at his disposal. I can't pretend not to be a bit envious...

* a soldering iron (good quality, ask for help at the store where you buy it). [Murray] has a __Goot PX-335__ 85-120 Watt with automatic temperature control, but that's kinda expensive unless you plan to do a lot of soldering
