Robotic Drives & Physics, course 3 in Robotics: Learn by building series
Parts & Materials for those not getting the Jet Pack Academy kit:
many parts from the previous courses, namely breadboard, jumper wires, Arduino Uno, multimeter, etc...
-rulers or wooden sticks that can be used as levers, as well as rulers to measure distance traveled
-very light spring scales
-low pressure air pump (searching "micro air pump" on ebay, amazon or banggood brought up the pump I use)
-low pressure water pump (searching "micro gear pump" on ebay or amazon brought up the one I use)
-2 air cylinders of different diameters (we'll explore how to build your own in the lessons)
-tubing to connect your air or hydraulic circuits
-pressure regulator that will allow very low pressure (<20 psi or 115 kpa)
-low pressure relief valve of some sort (we will explore how to build your own in the lessons because it is unlikely you'll find one suitable)
-pressure gauge compatible with the air and hydraulic pressures you will be running
-spool valve (unlikely you will find one, we'll explore how to make your own)
-pop or soda bottle to be used as a compressed air tank
-braided wire loom, sometimes called wiring harness
-long balloon to act as a bladder in the wire loom
-zip ties or something to clamp a hose or connector to your balloon
-2 solenoid valves. Searching ebay for "6V micro solenoid valve" brings up suitable valves
-pulleys & string or rope
-bag of gears (searching ebay store GC electronic for "34 kinds plastic gear set" brought up the set I include)
-brushless DC motor (search ebay or amazon for "12V micro DC brushless planetary gear motor" or possibly the model number XF08F3001)
-6 X 5V logic level MOSFET's like the FQP50N06
-battery pack(s) suitable for the pumps you get get
-rubber compatible oil or grease. I'd recommend silicone grease
-simple construction materials of your choice: cardstock, foam core board, wood, or plastic.
