I would highly rate the Laser 4/6. It comes complete with a mixer in the TX which saves you putting one in the robot.

Hi

Im looking to build a lifter/flipper in my bot taking this into consideration- less than 100 psi, easy quick and cheap(£40-£70) to build, takes up little space. I was thinking linear actuator unless someone else can think of something that fits the spec

think about using a window wiper mechanism . Im no expert but they are cheap and can lift alot , im not sure about space wise though

well funnilly enough i bought a 10 pack of ww motors. Ive got a reasonable amount of room. Could any1 give me info on ww system or other systems

The WW Mechanism sold by Technobots isnt really suited to a featherweight lifter mechanism. Maybe if youve got a welder and lots of extra space in your robot, it might just work. If I were you Id start looking for a decent and compact linear actuator to buy with your £40-£70. You could probably make quite a decent homemade one if you put your mind to it.

Na when you get free money spend it, dont make a homemade one. How bout http://technobots.co.uk/en-gb/dept_528.htmlhttp://technobots.co.uk/en-gb/dept_528.html KIT D. Would that be ok?
Can anyone explain how a motor lifter would work like the ww one?

Sorry i didnt mean a window wiper i meant a window Winder , It is in the side of the door in a electric car windows it can lift quit alot att hight voltage

Might be worth looking at a Zeobot type actuator http://www.technobots.co.uk/en-gb/dept_528.htmlhttp://www.technobots.co.uk/en-gb/dept_528.html you can either buy the kit or make your own. I made one a while back and used a threaded rod from a workmate and put a drill motor on the end.

ok. well any opinions on the zeobot actuator?

Space wise I have about 40-50cm length and bout 20-30cm width

We use an electric window winder mechanism from a renault with its stock CIM motor and we can easily lift 35kg with a 50cm arm on 12v with the unit held in our bench vise. We have put two of these in our lifter bot Haemorrhage and our new one. Haemorrhage has a drill motor adapted for its so it can lifter within half a second on 12v while the new lifter bot has the standard motor and can lift completely in 1 sec on 24v.

I can supply some pictures and possibly a small video is anyone is interested in the mechanism and how weve wired it up.

I would be interested in that, Im looking at the possibility of using a similar system and it would be great to have some pictures of how it can be done.

Many thanks,

those zeobopt motors dont really look up to the job for full on featherweight fights, i used one in the same way over2 years ago in ploughbot. lifted 6kg, but 12 it struggled too much. Robo Challenge use a Window wiper motor with a car jack on the end for the pit, it lifts atleast 80/90kg. I think your best bet is probably the same mechanism on a drill or gold motor, i have been trying to send some pictures out recently of mine, not sending though.

Ok well ive got plenty of ww motors at my disposal, im thinking of either a similar system to alans or a car jack. Any1 any ideas how heavy and big a car jack is?
