Write problem/project Goal
get the wheelchair running on its own sensing its environment.

My First Task
begin investigating battery charging

Summary of actual work over first weekend
I found out how to charge the battery's and created a tutorial

Week1 Narrative
I looked at the previous teams knowledge on battery charging and made a tutorial to show how to charge the batteries correctly. Here is the link to the tutorial

My Second Task
I am going to take a look at the joystick control for the wheelchair and see if I can intercept the communication from the joystick to the motors and make a separate motor control using an arduino.

Summary of actual work over second weekend
Time was spent finding each joystick online and there properties, also found a joystick hack someone already has done.

Week2 Narrative
I found a person who used a picAxe power board logic controler instead of an arduino, but he took a wheel chair opens the joystick, soldered some wires to his picAxe logic board, and could control the wheel chair. We just need to see how much of this we can create.

My Third task
I plan to recreate what this person with the picaxe logic board has already done.

Summary of actual work over third weekend
I worked on fixing the right motor which was broken and worked less on the joysticks.

Week3 Narrative
I opened up the joysticks and tried to see if any particular joystick was immediately clear to be connected to the original joystick connector. here are some of the insides of the joysticks.











I also made an inventory of all the joysticks we had so the next group will have a knowledge base of what we have.

After messing with the joysticks i spent a lot of time opening the motor trying to see how it worked and attempt to fix it. we found a bad connection so we solderd the wire back on and we got it spinning. below is the link to the pictures we found.

My Fourth task
I am hoping to make sure the motor is fully functioning and try and get the joystick interfaceing with the wheelchair.

Summary of actual work over fourth weekend
i finished the motor it is fully functioning at the same speed as the working motor.

Week4 Narrative
I tested the rotations of both motors under the same power to unsure they both work properly. Also got the wheel chair back together and I opened up the connector to find out the wires path to help find the best replacement joystick.
