Team Saint Robot Builds

[craig_colliass]

As always a big thanks to John and all the Robot Wars Crew for a great weekend roboting, This time Joseph (my eldest son) came along with me, as Zack was “revising for his GCSEs” I believe him.

This time I took Saint, Cherub, Seraph, Tron and the kettle.

As Zack wasn’t there I had to do some driving, and I suddenly remembered why I let Zack drive. Saint hit everything and occasionally the other robot. The fights were scrappy and hard I loved it, I think Saint saw action 5 times during the weekend and only had one failure when the split link on a chain failed one time.

Cherub didn’t miss a beat. It kept coming back for more and I think it only got flipped out once. By its team mate, thanks John.

Seraph was the worst performing robot the main problem being the motors cut out when you use full forwards or backwards with left or right if the control stick is in the corner, the robot just dies I have tried the usual things changed radio systems and adjusted throw but no difference with this fault, It started when I fitted those Botsbitz 85A speed controllers with a v-tail mixer! Any ideas welcome.

Tron was boringly reliable, and with the LiPo battery has enough power to push most of the other robots about.

Kettlebot just keeps going all I had to do was tighten up the screw that holds the lid, as it had worked loose other than that it kept the crowed amused. Oh and made friends with a bread bin. (That was a sentence I thought I would never write!)

Just a privilege to meat old friends and make new friends too. We are looking forward to the next one.

What code are the TZ85 running?
There is a thread with code that stops this problem when running with dx6i's

Still doing bits to tidy Saint this time its the hub caps.

The old plastic hubcaps got a bit worn and even started to crack a little!

I didn't have any green plastic the right thickness but had some white HDPE left over from the Gabriel biuld so that's ok.

OH by the way, the saw you see in the picture has been brilliant, it dose not clog up and with the big blade it cuts straight even with me using it. I got it from Argos.

A Big thanks to John and all the team for a great weekend at Barnsley, we managed to get both Saint and Cherub working for the whole weekend without any problems, had some good fights and looking forward to the videos soon.

Had a great Saturday evening with "The Usual Suspects" always a privilege guys.

Tron was going well and I even got a compliment on my driving from Zack.

The only robot to have trouble was Kettlebot we have worn out the motors in it! I have ordered some more as they are quite cheep. and it's an easy fix when they come.

Lots of people were away probably on holiday. but the shows were well received by the audience. And plenty of good fights were fought. I'm looking forward to the next one.

Dose anyone have any NPC T74 or NPC T64 motor gearbox units for sale, as I am thinking of replacing the drive system on Saint Cash awaits.

All stripped away

As expected the length is now about 200mm and the height is 140mm with the gauge (110mm without) this is going to be removed and replaced with a pressure switch to control maximum pressure to about 3Bar.

Everyone's in on the act!!

Looks good what is it for?
Specification?
weight lifted
overall length
stroke
pressure.

I am thinking of making one for a weapon actuator just to see how it dose

and Dave yes you were the only one who tried to stop it and did.

I made it just for testing to see if I could power a weapon with it, maybe a lifter or grabber.
It's made the same way as yours but with a regular bike inner tube (about 30mm diameter), 450mm long and has a stroke of around 80mm which is a bit pathetic! Braided hose goes from 30 to 45mm. In that video it is lifting around 100lbs at which point we ran out of weights to put on it. Looked like it could lift a bit more but as more load it put on it contacts less.
Was running at around 80psi but there was a leak somewhere so that kept dropping rapidly.
The encaps were made from aluminium and had a groove machined into them to provide more grip for the jubilee clip.

I wonder if you used stainless steel braided hose if you could run off full pressure CO2? Wouldn't want to be around during testing though!

After being ill over the Christmas with a bad chest I was able to get back into the garage to do a little bit on the robot the new motor mounts are now about finished and the new end plate is fitted on one side. the other side should not take long and then it is just a case of bolting it all together again, with the smaller motors I am hoping the Wotty will prove more reliable.
