This project has evolved some , the basic rundown is I'm modding two Omnibots , one a regular the other a larger 2000 model. I will have two ezb kits , rad base idea was thrown out because of so much noise but could go back on the table if the omnibot drivetrain is too weak to pull it.

Josh. It looks like you are going to make a hundred posts soon.
Oh it's well over a hundred posts, that's a hundred pages......
yep thats that i said awhile back,some of it off topic,but most has good info from everyone
soon as i get my hand gripper parts in,looking to post my hand part holding a beer,but its only the gripper part,then rotate is next ,its using the OMNIBOT 2000 HAND
building any type of hand you need to start FIRST at the gripper part,and weigh it,then use a formula to work out the rotate part,then add up total weight for the elbow lift and so on this way not much rework,also on selecting a servo also work out half the torque rating,first to save alot of battery power,second stall torque over heating (smoke) if you stay at 50% rating ,it can handle bigger load if needed
I wish I could do things that way. I on the other hand do not calculate anything. I get an idea try it, if it works great if not I try something else. Probably why I cannot do anything once. Always a rough draft.
@SFOY if you need help i can help you no problem,since i have much much experience on designing and building robots,not much on art or drawings or crafts like you are able to do mostly i am test and design engineer,thats why mostly you will see me talk alot about testing sensors and servo's and other electronics ,before i even start on a robot project it save so much rework,buying extra stuff not needed or wrong parts like servo's
rtying to help JOSH build a good robot design without wasting to much money
lot of us dont look at battery drain,everytime you add stuff to a robot it adds more weight then more drain on a battery,using a bigger battery only makes it worse,because bigger battery adds more weight ,so more drain on a battery, using a servo's at the rated torque drains it alot,but using one at double the torque and half the power you save on battery drain,same with adding sensors more you add to a design it drains more,using very low current sensor use save alot,same on electronics ,leds and more toy robot hacking is easy ,but fun ,but building large robots are much harder, omnibot 2000 is mostly a toy robot ,great for hacking and adding other stuff large robot much different ,mostly made from scratch using aluminum angle and aluminum parts,like ones i made and design
Well I am great at wasting my money.
Josh seems to be more of a planner than myself. I have no doubt he'll make a quality bot.
@JOSH you said you are using 2 EZB ,i posted info i made before for microprocessor design where i need more analog ports i did a post on it to add up to 8 more analog sensors using only 1 chip ,thats a total of 15 analog ports for about $2 plus only 1 EZB ,same can be done with digital ports too adding more analog ports to EZB
@SFOY i am too,mostly buying every sensor made to check and compare each one before adding to my robot design,best part is testing them much much FUN my lastest sensor is EEG sensor i am designing,it measures your brain waves (best way to explain to others) and use your thoughts to control robots
there is one i bought also ($350) EMOTIV EEG headset that does control most robots ,like wowwee robots and rovio,hopping soon DJ will have a interface for EZB the headsset comming in about 2 weeks,i think it controls SPYKEE ROBOT too
I'm not completely sure about two ezb but I'm betting I will have that many ports used up lol.
@sfoy thanks Sam! Lol I have invested way more planning than any other project so I believe everyone will be happy with the product
one reason I'm doing things the way I am is so its repeatable and I can make fiberglass copies of.the body and sell them lol.
