Smart Robot

Purpose

• Similar to the iRobot/Roomba Vacuum.
• Entertainment.
• Doesn't really have a big purpose.
• Helps you learn how robots work when assembling.
• Turn around when it bumps into objects.

how it works

• Motor powers the axles to rotate.
• Moving axles cause the sphere to spin.
• Weight causes continuous spinning motion.
• Pushes against the robot forcing it into motion.

diagram

• 1 top cover
• 1 large axle (with single cog)
• 1 metal weight
• 1 battery case cover
• 1 motor housing (with switch and wires)

DIAGRAM (CONTINUED)

• 1 motor housing cover
• 1 base
• 1 half sphere (with switch hole)
• 1 half sphere (without hole)
• 1 soft plastic ring

DIAGRAM (CONTINUED)

• 1 small axle (with two cogs)
• shorts screws
• 2 terminal caps
• 1 long screw (for securing the connection tabs)
• 1 motor (with wires and worm gear attached)

Problems

• 2 wires broke.
• Terminal cap would not fit into shorter connection slot.
• 1 battery wire & 1 motor wire became disconnected..
• Instructions were misleading.
• When sphere was tightened, motor no longer worked.

Changes

• Used soldering gun to reconnect wires.
• Removed part of the wire covering.
• Used pliers to fit terminal cap.

science concepts used

• Wheel and axle.
• Uses electricity from battery.
• Electric motor

Conclusion

• Waste of money.
• Poorly made.
• Uses electricity and wheel and axles.
• Bumps into objects and then turns another direction.
• Fun to watch.
