I have got a rolling chassis for SucculANT and it can drive around on a vertical surface. It has taken three weeks just to perfect a seal that can suck down from the normal non vacuum position while still allowing driving with and without suction. It has a two stage seal the first a flexible one tha...

Basically the higher the value of the capacitor the lower the frequency it will filter out. !0 uf is way to high at that value it will start to smooth out the speed controller switching and there by increase the dissipation in the output FET's. Try using 10 nf one from each terminal to the case. If ...

I dont see how you can have to much slippage zero friction would be nice. At the moment when the unit is fully sucked down the ant wont move. I selected ptfe for its low coefficient of friction but I only have 1mm sheet which is too stiff to seal and that extremely thin plummers tape which is easily...

I expect the robot will have to absorb more of the impact but hopfully the design the can withstand it. :wink: What I want to avoid is going out of the arena. Initial tests show I can get many pounds of downforce but cannot then move. The compromise is to balance downforce against movement using a s...

Actually I was joking I am playing with a vacuum pump trying to produce a little down force to stop my spinners from flying out of the arena. As expected there is no problem in sticking to the floor tha trick is being able to move at the same time. I wish I had paid more attention to vacuums design ...

You disconnect the mechanical drive to the pot but there is still the chance it could move and there by change your zero position. It is nomal to put a small amount of glue on the pot to stop it from moving. Make sure the glue get no where near where the wiper touches the track as this can cause pro...
