Nerf Assembly – 3D Render

Keith has been working with a tool called “Fusion360” to create the 3d models for our robot. This can then create the 3d printing file as well as laser cutter instructions. However – one other feature is that it allows you to create an animation of the 3d object!

This video shows our Nerf mount!

Nerf gun mount

Keith has been doing some more model work in Fusion360 (not on the cat walk!) So far he has the guts of the Nerf gun launch system and magazine modelled, and work has started on the mount system.  Over the next few weeks hopefully he will get this finished and we can get the parts cut and printed and trial fit them to the bot.

Power supply and motors

Keith has been playing about with a new cheap power supply using the Nerf Gun motors as a test bed.  It turns out power supplies are quite a good method for determining how much current they draw and thus what current the motor driver needs to deal with.  Keith produced a quick video demonstrating the power supply with examples using the Nerf Gun motors.

If you are still deciding on motor driver...

The Duck Shoot

The first challenge the team want to tackle is “The Duck Shoot” as this is new to this years event. The challenge involves shooting five targets down over three attempts.

Since the rules allow Nerf darts to be used, Phil went out a procured a nice looking, powerful gun!

The Strip down!

The only bit we need of the gun however is the dart holder and the firing mechanism...
