I’ve spent months planning my next CATPOO and it’s all printed out. All requisite parts are either here or on their way in the mail.
Highlights include:
- Omnidirectional wheels for holonomic goodness
- Infrared night vision camera
- 16x High intensity IR LEDs
- 7″ LCD with touchscreen
- External USB and network ports
- Wireless AP support
- Rear motion sensor for Spidey Sense
- Forward and rear proximity sensors
Once I get the few minor parts remaining from Pololu, I’ll be ready done with the building in a day. If you think you might need it, and it’s only a $1 or $2, just get it. Waiting three days to finish the build because I’m short on 1″ #4 screws is a terrible experience.
Once built, I’m nervous when it comes to figuring out how to coordinate all four servos to move in a straight line. Previously, I ran into trouble with getting the forward and reverse speeds to be equal. It could also be related to the servos I’m using. I plan to isolate whether it’s my fault, the motors’ faults, or a combination of both. I’ll have eight servos soon.
If I can’t get four functional servos out of that, I’m smashing the servo controller I have a sledgehammer and switching to stepper motors. I didn’t want to spend the money or effort, but it’s looking like that’s the direction I’ll be going.
