Robo Challenge - Predator

Re: The latest machine from Robo Challenge

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

Re: The latest machine from Robo Challenge

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!

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.

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.

Re: The latest machine from Robo Challenge

Scorpion brushless motor with a custom 10mm shaft and square end for slotting the drive gear on.

Re: The latest machine from Robo Challenge

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

Re: The latest machine from Robo Challenge

New head mount in place, new drive mount and batteries in place.

[james...venom]

Re: The latest machine from Robo Challenge

close up of the drive motors in place, first robot to have active suspension? will need it

Re: The latest machine from Robo Challenge

Looking real smart can't wait to see it in action

Re: The latest machine from Robo Challenge

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.

Re: The latest machine from Robo Challenge

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.

Re: The latest machine from Robo Challenge

That's looking awesome James. Really looking forward to seeing it finished and running.
