Peter Wallers Robot Ramblings

[haz]

You're welcome to some steel drillmotor ring gears and spur gears if you would like them.

The idea is to build an all around spinner so the ring gear needs to be a close to 100mm OD with as large an ID as possible to allow the wheels and drive motors to be enclosed.
If the ABS proves too soft I might try to cnc the gears in fibreglass.

Sure it wasn't Mr Tubbs Peter?

Yes thats the one I have just found a picture of it along side the one I remembered which was Angus.

Oddly enough I am trying something similar but with a plain ring and a friction drive rather than actual gears. If I can get it to work in time it will be at the next AWS

I just checked the speed and it is doing 6700 rpm on 3 cells.

Where did you get that montage picture Pete? One of those robots was mine!

[peterwaller]

It was one I put together of various pictures I had taken and I used it as a poster at one of the Brighton Model Shows some years back.

[Hogi]

might put it on my computer background. it's an awesome montage!

[peterwaller]

Made a little more progress have now scaled it up a bit until the outside diameter is 98 mm to enable the two motor gearboxes and reasonable tyre to be fitted within the inner diameter.


All up weight so far is 74 gms.
