Very nice James.
Than,s very much Shane, was hoping to have it ready for the champs but that doesn't look likely lol
Pretty cool how you made it onto the banner without even finnishing the robot! lol;

Haha, Dan took that photo at last year's Champs so I sent it to Kane. Thought it would make a good banner.
lol How good is that :)!
Doing a bit more work on it today. Designing the single tooth rim for the head and Im working on the arm mechanism. Its coming together
Well with the uk champs over its time to get back in the work shop, in fact I've been there most nights since the event!
Thanks to Sam Smith for the brushless motor for predator. I'm cracking on with designing the new head mount for the disc at the moment. Should be good for a test spin in the next few weeks!
In the mean time... I'm continuing with my crusher project (not many of you will know I had one). Il be working on both robots now until they are both finished. The crusher will be my real competition machine and was always designed to replace Venom and push the boundries just a little. Seeing Kennys new machine in action really inspired me to get cracking on it again.
Made a fair bit of progress this week :) today we was the first time we fired the basic system up and performed some pressure testing, everything worked perfectly which was fantastic to see. Pictures to come :)
working on the ram today. All the bottom half is complete, just making the piston and cylinder top then its off for pressure testing! We have tried to make the ram as light as possible so we dont know if it will stand up to the pressures or not so fingers crossed!
Project - Crusher
So here are the first few pics of the hydraulic valve being tested :)
We have created a manifold for the custom valve and I have added large ports just so it will fit KanFlu's test rig. Big thank you to Andy Kane and the team at KanFlu for all there time and help with this project!
Notice the serial number on the valve? Its the only one of its kind. Thank you very much to Moog for sponsoring this custom 2 direction, proportional micro valve. Its smaller than a 50p and will allow us to speed control the arm up to 3000psi. It will be buried deep inside the machine because there are no replacements for it... spinners please dont break it!
Project - Crusher
All ready for the first pressure test! Thank you to Sun Hydraulics for sponsoring the pressure relief valve.
All works brilliantly, was great to see the proportional control of the valve.
Project - Crusher
Here im cutting out the piston and ram top for my custom made ram from 7000 series ali.
Project - Crusher
So here is the custom ram I made a while back with hte piston and rod. Just need to finish the ram top cap and then its back to KanFlu for pressure testing on their rig.
Predator
Lots of progress made this week! Really pleased with how Predator is coming along. I am going to ask the moderator to rename this thread Robo Challenge - Predator so its a little less confusing sifting through the 2 robots and then create a new thread for the crusher.
So here is the new head block for the scorpion brushless motor. really pleased with the finish.
Scorpion brushless motor with a custom 10mm shaft and square end for slotting the drive gear on.
This is a prototype drive motor and battery mount machined from 10 mm polycarb. Im trying to get some flex into the mount which will help with the suspension
New head mount in place, new drive mount and batteries in place.
close up of the drive motors in place, first robot to have active suspension? will need it :)
Looking real smart can't wait to see it in action
Thanks dave!
The arms aren't finished yet but we gave it a shake down test last night on half voltage which went really well. First test at full voltage will hopefully be at the DRG event this weekend. Shame I dont have another week as it could be finished then. Once its tested on full power we just need to make and fit the tooth ring, the arm mech and the armour.
Decided to go brushless in the end eh?
Fancy donating that Astroflight motor to Team Bitza? :wink:
(Can't buy things new, not in our ethos)
I'll pay you back in sound.
That's looking awesome James. Really looking forward to seeing it finished and running.
Looking really good James!
Thanks guys really appreciated. Video to come in the next few days :)
looking awsome James!
I saw it last week in belgium, looks so nice! Good thing the disk don't have any teeth yet.
No Viper series 4 had suspension, it arguably didn't need it, looking good though.Quote:

The head is powered by an HK 3226. Way more power than we need.
So here is the first test of Predator :) Just the drive system, tail and head are working. The test was in part to spin the head up but mainly to check the balance of the machine and how it reacts with the head up to speed and under acceleration.
Tests were positive :) The head spins up too quick if anything. if you just go to full speed the robot flips over. Once more weight is added it will help but it will still be an issue. Once up to speed the drive is very good, even with the head tilted the balance is nice which gives it a very smooth drive. Very different to driving style to Venom.
Overall we are very pleased. Just finished producing a new dive mount to alter the battery positioning and ready to continue with the next stage.

Using a scorpion commander esc and 6 cell lipos.
Won't the arms being down sort that out?
very nice James.
Thanks very much Shane. Yes the arms being down does make a big difference. I wanted to test it in the worse set up scenario... against a flipper where the arms would need to be up ready to selfright. We did run tests with the arms down and it was very notice able.
Properly cool, James! Does look pretty nice to drive, even at full speed. How much will the finished head weigh, teeth and all?
And, do you intend to use Predator in full combat or just for demonstrations and such?
Can't wait to see it in anger, it's really looking good. :)
It will be for full combat. There is approximately another kilo to go on the disc yet. Amazingly the robot as it stands only weights 8.5kg so there is 5kg to add the tooth ring, finish the arm mech and armour the robot up so im really pleased.
Does the moving tail have a purpose or is it just for show?
Looks awsome by the way!
looking really nice ...well done James :)
Thank you for the comments, its really appreciated.
The tail is part of the machines shape to finish it off. it also serves 2 purposes. If Predator is caught up the tail does have a bit of lift in it to help it free its self. Also the electronics are originally designed to be in the tail. This would bring them as far away from the disc as possible to reduce the shock going through them from disc impacts. As space is quickly running out the speed controllers are now above the drive motors. The tail will house the link, the arm mechanism and maybe the head esc.
Looking awesome James!
Are you planning to fit some magnets to help with holding it down to the floor?
Its good to see you re-inspired on the build recently, look forward to seeing more of the build diary!
looks awsome james, looks alot like the HW predator and it looks like it will make alot of damage! :twisted:
More commonly known as Warhead :wink:Quote:
