Hello to everyone. I got back home from the hospital yesterday. My wife told me about her posting and I went to see all. I thank everyone for the nice comments , well wishes and prayers. I have a long road ahead but the doctors say I have very good chances of a good recovery. the left side of my body has been affected. I have difficulty using my left hand now. My speech is a bit difficult, and I have some memory problems. I can not begin to relate how frustrating it is when you can't seem to think straight. Sometimes simple tasks become difficult. the doctors; my wife have encurged me to continue with interest in robots and think that it will be good thearpy for me.I can only type with my right hand now so takes longer.
My robot projects will have to change for now.
My whole reason for building robots was in case something happened concerening my health.So, I have to now think about building a robot arm and hand to help me with doing things. I would really appreciate help from EZRobot family to design and build a robot arm for me to use. What with medicall bills I am on a kindof tight budget so must try to keep costs down much as possible.Welcome all input
I got a webcam I ordered but can't seem to recall how to install it. It is a wired USB cam. I am using windows 7. A litle help please.
I hope everyonewill not mind if I ask what may seem simple questions. Again thanks for all the kind thoughts and words. It means a great deal to me.

I want to thank you for the very nice thoughts. My main proget now, is making a robotic arm to help me with all my other tasks. I'm looking to my EZ Robot family for help with making an arm. Any help will be greatfully accepted.
Thanks everyone.
whats you power supply to the motors and EZ-B?
The motor drive is a L298N Dual. I have attached pics and a schematic. I am going to use 2 - 12 v. 9.0 A.H. SLA UB1290 or DJW12 batteries for motor power; and a 7.2V, 3800mAh Ni-MH for the EZ-B. Motor power will go to a terminal strip pwr bus (so I can power other 12V circuits), like lights etc.
@ jstarne1:
I would like to mount arm on a portable base ,maybe plywood, so it can be moved an atached to different surfaces with clamps.
The wole thing should be light enough for me to pick up with one hand. Thinking wrist joint so hand (gripper) can turn. The arm should be able to pick up hand tools and fine enough to hold solder. base would turn maybe 270 degrees. lift range maybe 0 to 18 inch es.
@ DJ:
Which do you think might work better for arm joints.......servos or DC motors ( like pitman) I am thinking lifting power. If DC motors, could EZ B be able to control them? I need some help with which servos to use that arm could lift around a pound?????
I have looked at www.servocity for parts. Am I making any sense here?
@ group:
I would like any help on ideas.
Thanks
Lloyd
What are you thinking for the arms? What material? The 1st thing that caome to my mind is U channel alumnum. I guess by the drawing you used regular hinges at the joints??? What is the block line running from the motor to the grippper?
I was thinking about the pan base from Lynxmotion for the main base. I think they said it could move a load of around 2 pounds.
please keep in mind that I will need to use as man y off the shelf items as I can.
@ DJ : Now would be a really good time to work on servo speed if you have the tim e.
In the situation for now I would also con sider using a reg R/C radio fo radio I am goingr for servo control. I have a 6 chanel to use for robo jeep, I could use it if I have to. Do you think I could use a movment panel for contoling a dc motor in the arm? Would I have to hook it up to a motor driver? I would think I would.
