Re: My meped just resets

Hi Grasshogger,

We will definitely be making a revision to the PCB and we're currently reworking the existing boards in stock by removing one of the diodes and replacing it with a jumper wire to fix the brown out issue.

Thanks for the feedback!

Re: My meped just resets

Following up on my previous post about removing one of the diodes and replacing it with a jumper wire, I was able to recreate the brown out situation using a fresh set of alkaline batteries. After that, I set up one mePed with stock hardware where the PCB has both diodes on it. I set up a second meP...

Re: MePed seems to get stuck

@Aztecphoenix, I had considered a spring/shock unit similar to what are on R/C Cars for absorbing impacts. The idea was more so to give the legs a little bit of flex as well as cushion each step rather than relieve some of the load being carried by the servos. I like your idea of relieving some of t...

Re: MePed seems to get stuck

Hi Knud, I apologize for the issues you are having with your new mePed robot. It is normal for the servos to hum and chatter a little bit when the mePed is standing idle and not moving. This is due to the servo constantly reading the internal potentiometer and updating the position based on the resi...

Re: Nuts and screws

Hi Knud, Thank you for the feedback on the mePed assembly! I have found that a pair of needle nose pliers help greatly when installing the plain nuts in those difficult areas. I hold the nut with the pliers while inserting the screw into the top of the leg plate. This keeps the nut in place so it do...

Re: My meped just resets

Hi PacMan, What you're seeing is a condition know as a "brown out". The Arduino is starting up and it begins to move the servos to their center (90 degree) position and this causes a spike in power usage. This can cause the battery voltage to dip just below the minimum threshold needed by the Arduin...
