Fighting robot dinosaur project... This is an RC 'robotic' dinosaur in kit form. It is skid-steered, the user controls the left and right claws (which rotate) using slider switches and 'fires' the neck/head/jaws which lunge and bite, driven by a simple crank. Two can be used to fight with. (https://www.youtube.com/watch?v=Xqj63r2-IeA&feature=youtu.be) It started off as a project with simple flat parts made by sticking adhesive templates on plastic boards and manually cutting out the shapes. All the working versions shown were made this way. However the parts can be laser cut (see pics) or indeed 3D printed. The non-printable parts are all standard engineering components and are listed in detail on the website. This should be a good 3D print project because there is a lot of scope for re-modelling the components. The parts were all designed to be easily cut out of flat material and assembled. There is a lot of scope for developing the basic design further. Another area of possible development is creating coverings (skin). Please get in touch if you would like information about obtaining the non-printable parts. You can use your own materials, improvise or get in touch if you want to buy them as a set. Acknowledgements and safety notes -see Instructions There are photos and instructions on how to assemble plus some videos -(including two fighting) on http://www.robokiller.co.uk. The idea was to make something that could be made and assembled with very simple workshop materials: a vice, a hand drill etc., without needing a lathe or milling machine etc. Also all the parts are as low-cost as possible and the motor/gearbox that drives the neck and jaws is from an economy cordless drill. There are no electronics. I've uploaded all the parts as .stl (and other) files along with the 'cutting board template layout' in case you want to laser cut the parts. Obviously some parts are best made from other materials, for instance the 'neck studding forward.stl' is a length of M4 threaded rod bent in a curve. (Parts created in Solid Edge). Please do let me know if you need any help. Nb if you do not have a 3D printer (or laser cutter!) you can download the pdf of the templates. These can be printed on A4 adhesive sheets and stuck onto 1.2mm thick board. Get in touch if you need more information.

SAFETY NOTICE.......PLEASE NOTE THAT THERE ARE MOVING PARTS AND SIGNIFICANT FORCES INVOLVED THAT COULD DO SERIOUS DAMAGE TO FINGERS OR OTHER BODY PARTS! DO NOT PUT FINGERS NEAR ANY MOVING PARTS WHEN IN USE. THIS IS NOT A TOY AND SHOULDN'T BE USED BY CHILDREN UNSUPERVISED. I ALSO RECOMMEND THAT YOU BUILD A GUARD TO COVER THE MESHING GEARS (NOT SHOWN). REMOVE THE BATTERY WHEN STORING THE DEVICE. THIS PROJECT IS UNDERTAKEN ENTIRELY AT THE USERS OWN RISK.
