Rough Renderings

We have created a rendering of the arm, excluding the gripper, 

to aid in the ordering of parts and serve as a discussion piece for conversations among our group.

Figure P2.1: Rendering of shoulder, elbow, and wrist joint positions

Shoulder and elbow joints will have the higher torque servos, HS-645MG

The wrist servos (rotation and tilt) and gripper servo will be lower torque motors, HSS-458HB

Figure P2.1: Rendering of joint design

This is the configuration of all of the joints displayed in the previous rendering.

Materials Order

Late last week we placed an order for parts for both the robotic arm and the sensor array.

This order included:
4.5 inch flex sensors from SparkFun Electronics 
Voltage dividers and sensor cables from Trossen Robotics 
Two different models of HiTech servos (varying in torque) and assorted servo brackets from RobotShop

The Engineering Design Lab also supplied us with a Pololu Micro Maestro 6-channel USB Servo Controller, the exact model that we had specified in our initial designs.
