Mr Smashy!

Pictures of Mr Smashy's Finished Frame

Here are photos and descriptions of Mister Smashy's finished frame. The frame is made of welded 6061 aluminum, and the power comes from 4 22V Dynetic Systems servo motors running at 30 volts each. They are controlled by a Vantec RDFR23 which in turn is controlled by a JR PROPO 622 6 channel FM ground tuned radio.

Here is a top down view of Mr Smashy's finished frame and wheels. There is a Deans Slimline Boat Antenna attached at the moment, out the side of Mr Smashy's frame. It should really be attached to a non-conductive surface, but I never got around to building a specific mount for it. Maybe next year! The box in the middle of the robot is to hold our BlueStar LiSO2 batteries. The foam tires ended up wearing down too much, so I capped them with pieces of inner-tube. They fit perfectly and are held on using contact cement (very messy!).

You can see the cap on the tire in this picture (you can also see the excess contact cement). The wheels are designed to accommodate armour plates made from hard-drive platters, but these haven't yet been attached, as they are not really needed until Mr Smashy competes. The aluminum tube sticking out of the end of the wheel may end up being cut off, as I don't think it is a good idea to have a leveraging point on the axle so exposed.

Here is a shot of Mr Smashy upside-down. You can see how the battery box is attached with wing-nuts. These are there for easy removal and switching to the Ni-Cad box, which is a different size.

Mister Smashy's secret position! Because the drive wheels stick out past the front of the frame, Mr Smashy can flip over, as demonstrated in this picture. This was done by design, You know Bob, design?

This is where the radio equipment has been mounted (temporarily). The box underneath the receiver is actually empty space, so it will be removed if and when Mr Smashy reaches combat. The white gunk on the batteries is silicone grout, which makes an excellent anti-shock adhesive. You can also see the gear setup in the photo reasonably clearly. Two motors a side makes for tricky gear lash settings.

Over head shot of the Vantec. It is coupled through two layers of mouse pad to the frame. You can see clearly the side plate of the wheel to which the gear is attached. There are 8 4-40 bolts through the hardened steel gear, into the 3/16" aluminum plate holding it on.

Here is a shot underneath the radio equipment side. You can clearly see how the axle (made of 1/2" 2024 Al) is bolted into a solid block of 6061 Al which is welded to the inside plate of the frame. It feels really solid. The ends of the axles are tapped and the wheels are attached with bolts and washers.
