nice fabrication skills mate!

[psycho_fling]

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

[plargen]

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

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

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

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

[plargen]

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]

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.

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

[plargen]

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
