Ok I've been out of the robot scene for a bit and our new makerspace in Pensacola ECCMakers.com
has pulled me back in. I don't have much time to work on stuff any more after starting my own company but I did do more work on an old project to showcase at a makerspace event today.
Here is a video of the bot working just fine in my house.http://youtu.be/5AFr27_udME
It even worked in the space this morning.
The event was a sustainable concert that (with some makerspace help) built a solar and pedal powered PA system and had an all day concert and the PA system was off the grid the entire time.
We had a booth for showing off projects and I tried to get my bot to work in the parking lot.
I have 3 continuous rotation servos with Omni-Wheels, An Axon II, and 3 EZ1 Sonar sensors.
I didn't have time for full blown Omni-Movement so I compromised with just backing away from anything when a sensor read 25cm or less. Rotates for 0.5 secs if two sensors trip.
Works as planned inside but I take it outside and it just rotates. So the only explanation I can come up with is something is screwing with my sensors and they are tripping early.
It is really close to the ground so I put some spacers on the sensors and tried to get it off the ground more. It still just spins.
The parking lot was a bit rough but I found a small and level concrete slab. Still rotates.
So any ideas on what might have been screwing with my sensors?
