Brazing (like welding, but way easier)
Ever wanted to weld but always had a good reason not to? Brazing is a much
better option when making small and medium size robots. The power of welding
for under ~$60, and easy enough for a complete novice to self-learn.

FEA Finite Element Analysis Tutorial
Learn how computers can be used to computationally simulate and optimize
the mechanical structure of your robot.

Robot Chassis Construction
Do you know the parts consisting of a robot, but not quite sure how
to put them all together? Need to know how to say, attach a wheel to a motor?
This is what you need to know to construct a basic differential drive robot chassis.

Robot Suspension System
The problem with a typical suspension system is that its very complex and involves many parts.
As a solution, I invented a new type of robot suspension consisting of one single flexible part.

Theory: Statics
Want to optimize your robot parameters mathematically? Want to verify that an expensive
motor you are about to purchase has enough torque?
Calculate things such as moment arms, gearing, friction, torque, and more.

Theory: Dynamics
Mathematically optimize your robot further by calculating things
such as velocity, acceleration, and momentum.

Theory: Energy
Mathematically optimize your robot battery by calculating
the required energy your robot needs to perform.

Gears, Sprockets, and Chains
Learn theory behind gears. Understand how to calculate gear ratios, torque, efficiency, and rotational velocity.
