Re: scruffy

ok got mi new battery for night fury and so far i've gutted it to do a few mods and upgrades

the wheels are being change, the power distribution is being upgraded and im going to build a battery box out of aluminium and add some extra steel above and below it to help protect it from the crushers

Re: scruffy

ok got a bit more done on the latest bot

now my new m6 tap arrived ive managed to get the motors mounted and built a chunk of the lifter

Re: scruffy

ok tacked the top plates on now i need to decide weather to go for bearing or bushed (pics have the 2 options)

i know the brass bushes should take more punishment but i think the bearings look better

Re: scruffy

Looking really good! Hopefully it and Tormenta 2 get to tussle one day.

Also, the cooler a robot looks does seem to have some sort of relation to how well it does, but I'd say go for whatever will take more abuse, without doubt.

Keep it up.

Re: scruffy

im hoping to get it ready for the gadget show so it can do some whiteboard fights

Re: scruffy

nice fabrication skills mate!

Re: scruffy

looking great, i think you need to consider possible damage from other robots rather than any problems the axe might cause on eithther the bearings or bushes

so which ever will run smoother and then think about protecting it further - should be easy enough with your welding skills

Re: scruffy

ok at the mo trying to decide whether to put some large bits of rubber where the arm lands against the bot or to just to weld in some thicker steel to take the punishment ?

also i might make an axe for the bot as the drill is a 2 speed so it can move 3x faster

Re: scruffy

night fury upgrades

started to make the battery box for the lipo box, there will be a 10mm thick aluminium block at either end which will be tapped and bolted in. I'm also intending to add some steel plate above and below for a bit more protection i have also mounted the power splitter and fuse holder with 80a midi fuse and started to upgrading the wire from the battery to the splitter with 12awg

Re: scruffy

Looking very good. Axes sure are fun to watch!
Looking foward to see this robot finished.

Re: scruffy

What ratio did you use between the car seat actuator and the lifter arm in Scruffy?

[plargen]

Re: scruffy

the actuator sits about half way between the lifters wedge and hinge (give or take an inch) so the actuator itself probably put out near 50kg force

[Phil]

Re: scruffy

Thanks. I want to do something similar. My actuator has 50 mm of travel. I pushed it onto bathroom scales at about 55 kg weight of force. It was still extending, but I couldn't push any harder.

Re: scruffy

ok since it was a bit warmer i've manage to get a little bit done

ive fitted the 2 bumpers for the lifting arm /axe and cut the box section down to size and added a couple of support im intending to make a scoop lifter using a gas bottle which i will have to do some shaping to keep it wide and under weight

im also tempted to cut 3 bits of angle into wedge shapes and weld them onto a plate which will be which can be interchange on the lifter

Re: scruffy

as the armour is 3mm steel, i know the front 2 corners are in potential danger against spinners so im wandering weather to weld some 3mm strips on the corners to increase it to 6mm or weather it would be best to bolt either hdpe or some aluminium or even some stripped of grade 5 titainium ive been looking at

i'm already working out if i can save enough weight to put some 10mm hdpe panels on the sides or possibly 5-6mm cheap aluminium
