Harry Makes Ants

Post by haz » Wed Jul 11, 2018 3:59 pm

Yo. It me.

Antweights have moved along a lot in my semi legit hiatus. I'm glad to see there are so many people doing cool things still. I'm going to try and catch up and drag myself (and the amazing Mr Blunden) to an AWS.

Anyone who follows my Facebook drivel will know I've pumped out a couple of critters in the last few months after the inclination and drive for larger, more complicated (expensive!) robots dwindled.

Going to try and keep updates here as well because I rather miss forums :)

LOADER was my first toe-dip back into the waters of antweights. A relatively boring pusher with silicone tracks (hair bands) A printed frame and a 1.2mm titanium wedge.

I tried to get this to one of the last few AWS's but life happened and it got thrown at Joey to run as a rail replacement bus robot service.

You can see a video of it here: https://www.youtube.com/watch?v=Ow2AVVfpsCo

Next up is a strange ghetto replica of hypnodisc. I'm not sure why this came to be exactly. I think I had an excess of bevel gears and 2mm bearings and this was the next logical step.

It's pretty much done except for getting a metal disc cut which will be done when funds allow. Hugely underweight, its only 107g!

Next up is me trying to have a go at something that has long since been a goal. Pneumatic. I went for the simplest system I could find with as much off the shelf components. Sacrificing shape and weight for stuff that would just work Luckily, that paid off and I have a very reliable system with zero leaks. Flow rate is okay. Retract is good. Only problem is its ugly as all sin! :( I will be taking what I learned from this and moving on to a whole new scratch build with slightly more custom parts.

Still need to do some armour for it. 1mm hdpe bent and folded is about all I have weight for!

Hope to actually keep this page updated with antweight stuffs, thanks for reading :)

Thanks guys!

I'd been having some problems with stiff retracts. What used to be a snap shut was a slow pained series of events. Everything mechanically seemed free and the silicone bands still had spring. Ended up stripping and re greasing the ram and it seems much better since.

^^ the setup out of the robot for anyone interested!

After a couple of attempts at armouring it was going to be way too flimsy for combat, even for a sacrificial first attempt. I ended up swapping out the 35ml tank for a 20ml one. I'll take the hit on flips for the benefit of actual armour not just pish and hope - also lets me chop the frame by 20mm! An updated one is printing as I type :)

The smaller tanks are ones I had ordered for my second go at pneumatics so it is maybe a good thing to trial them in this bot. I have also found a much nicer servo to actuate the valve, physically smaller and with metal gears. Bonus!

haha Voorsk, then I feel I must apologise to your son for my naff performance! If you're interested files to make your own Hobgoblin can be found here
