Yes, I have a mouse for sanding up to 240 , then I wetsand by hand 320 and 400 grit. I really hate sanding lol but IM good at it.

Lol , your right Steve he took a giant leap in progress all of a sudden. He free 13 inches and now has side cooling fans and a front recess mount for a 7 inch Tv screen. Some sensors will be rarely used but for experiment purposes they could be nice to have.

i hate sanding too,but have awile before i get there most likely the hardest will be programming ,because of a lot of sensors and servo's

@ josh

Do you know about sensor redundancy?

if you have 2 diferent sensors doing the same thing then the chances of a false reading is reduced many fold.

EG

a sonar and a ir distance sensor faceing the same direction . if 1 misses somthing the other will probaliy see it.

no sanding needed on aegis . im going for the battle scared and weatherd look.

if it looks to shiny then im going to distress it.

and no sore fingers.

Yes I have both IR and Sonar on my radar turret =) the IR has a much wider field of vision so I can use either. Plus my radar will be on a tilt bracket so it can be adjust from being level to pointed at a downward angle at any time =)

steve you are right on the sensor i did a post awhile back on sensors IR and SONAR and how to place them on a robot and why IR is prone to light or shiny objects or mirrors,so they are needed near the bottom of the robot also for detecting corners set it vertical

on SONARS anything foam,cloth ,sofa's and more it will give a bad reading so place near the top of the robot if higher then a sofa if small robot kinda hard ,need to set it at a angle and offset the distance, to make it detect small poles like legs ,you reduce the SIDE SLOPE (cone) on it with a tube on the trasmitting side with sound asborbing material,on a lot of sonar ,some you get are unstable so 10 mfd on sonar pcb next to power and v+ and gnd it working on a circuit also to make 2 wire sonar (trig and echo) to a 1 wire PARALLAX PING design witch really is a bad sonar ,(accuracy) all sonars draw 30 ma to 50 ma except for maxsonar 3 ma and has the highest accuracy,plus ttl,pwm and analog besides trig and echo another one very good is SRF02 it has a I2C buss,so many many on one line
