what we want (#15, #10) can't figure out how to order it??? http://www.netmotion.com/htm_files/mc_slides_thom.htm

Very expensive!! https://www.technico.com/technico/category.aspx?SID=1&Category_ID=60

  • Load sensor

This one is SWEET! it uses capacitance to sense load... pressure on a capacitor reduces the distance between its plates... cheap and effective! http://www.loadstarsensors.com/iloadmini.html $100 http://www.loadstarsensors.com/products.html

  • Clamp?
  • base out of aluminum for robot
  • right angled pieces of aluminum for motor mounts.... and other mounts
  • little support bars or spacers for varying mounting distance...
  • Lexan to cover electronics
  • Mount for CMU cam
  • Battery mount - aluminum... (try base removal with a simple latch, like a jewelry box)

Electronics

  • Get the DP board done
  • Weight Sensor
  • iLoad Mini - interfacing
  • chips: 74hc541, 74hc138, 74hc238, max3232 - all soic
  • Buy another DP module, or ask from Student Govt.
  • Line sensor parts - decide on a photodiode/LED/combo, also maybe sample a nice adc (max1230)

try out the line sensor code with the small clear robot

  • dip led 10-seg modules
  • Color Sensor - try it out (instead of CMUcam)
  • various headers - find some in the trailer
  • find the LMD18200ts fez sampled some
  • passives
  • more headers, maybe some in 3-row
  • steal the maxbotix sonars back from pickle or use i2c and all those srf08s
  • some serial connectors with solder pin, just for general use
  • a nice lcd and nice big led numbers for the weight
