How to build a snake robot

Step #1:

Nagaina The Snake Robot

Design is key! Use solid works or Google sketchup to plan out the elements of your snake bot
The key is to mount the wheels on rubber bands to insure ground contact at all times
Cheap servos will work but the stronger the servo the faster your snake will be able to move. This is because the limiting factor on robot snake speed is not the servo speed but the torque required to get accelerate to that speed.
Don't be afraid to add lots of batteries, weight is your friend on this robot. Not only do the servos use up all their stall amperage typically, but heavier snakes mean more wheel friction to help you move!

Conclusion

Lego Wheels are hands down the cheapest and best in size.
