im currently building my featherweight at the moment and have changed design from pneumatic flipper to linear actuator crusher.
- making a razer style claw
- linear actuator in base of robot
problem
- making the straight movement into crushing power, at the moment it holds gently or drags claw backwards . Help needed . thanks
will try and get picture on profile later to help :)
Id make the claw and actuator assembly something like this .. +1>-------+2>C+2>.
where the --- is the actuator C is the claw and . is the claw pivot point.
Moving the actuator connection point up or down the back of the c (claw) will give you various jaw openings and crushing power.

thanks for that idea, simular to dragons claw.
how does a razer style claw work then ?
pictures of testing can be found on http://www.freewebs.com/snowshifterswww.freewebs.com/snowshifters ,this will give you an idea of what im trying to do.}
Razers claw works almost the same but with the pivot point and the actuator conection swapped around. The simplest way to explain it would be to have a bar of some sort, put a pivot in the centre and push on the bottom. This would rotate the bar. All you need to do then is shape the bar to a curve, work out the best distance between the actuator and pivot and your well on your way to a razer type crusher.
Flow! is nearly done so i thought i would post the specs.
Name: Flow!
Armour: 2mm Stainless
Chassis: the whole chassis is 16mm nylon the base is routered to 5mm to loose weight
Drive: Bosch 35s
Power: 2 x 7.2v 2.3ah race packs giving 14.4.v
Control: 2 x electronize and specktrum
Weapon: Full Pressure 60mm bore by 95mm stroke Square ram, fired by a burkert, fed by a 3 x volume buffer, from a 20oz paintball bottle.
Just to mention, as we dont have the weapon system of Hannibalito II anymore, I had a month to create a new weapon system.
Hannibalito III is a strange fish in our stable.
The ram is diminished from 61mm bore 80mm stroke to 51 mm bore 75mm stroke.
The drive, from the hugely overpowered Speed 900s on a sidewinder with 18V 3600mAh NiMh Sanyos goes to the feeble Speed 720 BB torques on a Scorpion XL on 2300mAh batteries.
In other words, its an efford to avoid Self OOTAs
No it isnt.
Mario, are you using the same inlet to your ram as H2?
If so H3 may well be a better flipper as theres less volume to fill up with the same flow :proud:
