ShopBot
Project Brief
  • Autonomous vehicle that will detect and collect
    ferrous tools/hardware from a garage floor in a
    random pattern
  • Based on 1/16th scale R/C tank chassis
  • Behaviors implemented include metal and weight
    detection, obstacle avoidance, positive object
    grasp

3
ShopBot Platform/Drive Systems
  • Dual Clutch Servo Controlled Directional System
  • Servo Speed Controlled (3/1)
  • Metal Tracks/Gearbox
  • 7.2V 3000mAh Battery (Drive System Only)

Dual Clutches

ShopBot Platform/Drive Systems
  • Arm will rotate in a circular path from ground to
    collection container _at_ 30 to ground
  • Electromagnet will grasp item (uses two D cells)

5
ShopBot Computer/Hardware
  • Atmel STK500 Development Board with ATMega128
  • Discrete power supply for processor
  • Electromagnet controlled by power-FET with logic
    level gate drive capability

6
ShopBot
Sensors
  • Metal Detection
  • Hall Effect/Proximity Sensor targets ferrous
    objects
  • Sinking output (negative logic)
  • Located inside vee aluminum corral with
    bumpswitch
  • After detection, will back up to place arm over
    object

ShopBot
Sensors
  • Weight Detection
  • Target weight lt 1 pound
  • Sensor consists of calibrated spring mechanism
    that deflects with one pound

Negative V
Weight closes the contact
Electromagnet
Positive V

ShopBot
Sensors
  • Obstacle (Wall/Large Object) Avoidance
  • IR Ranger mounted in array on top
  • Angled to detect walls of garage, but not low
    profile tools
  • Arm bumpswitch
  • Ensures positive engagement of target throughout
    arm rotation
  • Also will reveal release of tool into basket.

ShopBot
Conclusions
  • Feasibility of electromagnet still questionable
  • Completed simple experiment with nail and wire
    wrap wire (picked up wire wrap tool and IC
    extractor with 1V)
