The Raspberry Pi used is headless, a technique I've used extensively in [Learn Robotics Programming](https://amzn.to/2RZqPIy), my book on the subject. The Bonjour/mDNS/Zeroconf system is used to find the Raspberry Pi on a local network without needing to know it's IP address.

You can cable tie wires in bunches with these. These are extremely cheap and convenient, and are the quickest way to get a little control of cables. They are the kind of item most electronics or robot building enthusiasts should have around. However, they may mean needing to clip the cable ties back off if you want to make changes. It can still bunch though.

An absolutely essential tool for this is a set of digital calipers. They need not be expensive ones, although paying more will give more precision, even a basic set will let you make precise measurements.
If you or your kids are just starting in creating robots with Lego, it might be a great time to buy a starter kit. The LEGO Boost Creative Toolbox Robotics Kit offers simple programming for an absolute beginner, making satisfying mechanical builds with smart programmable behaviour.

They are pretty good for complex terrain (depending on the flexibility and control systems) and along with quadrupeds, are also among the most common Legged forms.
