Yeah.....to bad that that he lost vs Resurrected...if they had a roof on the robot they could have wone the competion.....
Ehm, Craig, I got the award for best technical engineering, Vacuum was awarded with the most original design.
Gary, I looked att your tech page, but I dont get how I should mount all the things on the flipper arm...
And is glassfiber god as amour?
Hi Joacim
The flipper arm is yellow, the servo arm is green. The flipper is hinged to the robots body at point D.
The linkage between the servo and flipper (red) must be free to move at both ends. The linkage could be piano wire or a recycled paper clip, with a bend in the end so it fits in a hole in the flipper.
Unfortunately I dont have any pictures of the linkage on R.O.N.N.Y or RampAnt. If I ever figure out how to take a good picture of the linkage (its hard to see when the robot is complete) I will add some to my site.
Glassfibre is certainly light and is fairly strong, but its main benefit is that it can be moulded. If you can make a shape that will deflect the impact from spinners then you may have an advantage. Carbon fibre is lighter and has been used to good effect. Kevlar hasnt been tried yet AFAIK...
thanks, but was makes the diffrens between having the servo direckt to the arm or having the link?
Its all about getting the right leverage ratios with the flipper and getting the servo lower for a better Centre of Gravity
Also, the link allows the flipper to be hinged to the robot body. With a direct connection to the servo, the only place the flipper is connected to the body is via the servo output gear.
The link is also the weakest part, so it breaks first. With the direct connection the weakest part would probably be part of the servo. We have suffered lots of flipper damage, but never any servo damage. (And I know which Id rather replace!)
Is´nt it esyer to modify the servo to 360 degrees?
I write that abot 3 month ago, and still no answer.......
