From Foot Pump Cylinders To Pneumatic Robot Fighting Arm

[James Bruton] is well known for making robots using electric motors but he’s decided to try his hand at using pneumatics in order to make a fighting robot. The pneumatic cylinders will be used to give it two powerful punching arms. In true [James Bruton] fashion, he’s started with some experiments first, using the pneumatic cylinders from foot pumps. The cylinders he’s tried so far are taken out of single cylinder foot pumps from Halfords Essentials, costing only £6.29, around $8.11 US. That’s far cheaper than a commercial pneumatic cylinder, and perfectly adequate for this first step.

He did have …read more

A Home Made Air Pump From PVC Pipe

If you need a supply of low pressure air – let’s say enough pressure to ensure a constant supply but not enough to describe as “Compressed air” with a straight face – what do you do? Many people will reach for an aquarium pump, after all that represents a readily available and relatively inexpensive source of bubbles.

But not [truebassB], instead he built his own air pump from first principles (YouTube, embedded below) using PVC pipe. It’s a straightforward design in which the cylinder is a length of pipe with a disc of flat PVC glued to its end, and …read more
