Week 4

Accomplishments

Mechanical:

• Finalize Catapult Arm mount and 3D print
• Design Latching Mechanism
• Assemble the Catapult arm

Electrical:

• Electrical board mounted to robot, assembly has started.
• Additional parts ordered (battery charger, terminal strip, switches).

Software:

• Connect Arduino to Raspberry Pi, which runs a webserver to take input remotely. This webserver can be accessed when on the same wifi network, which for now is a hotspot hosted on a phone.
• Connect a Ultrasonic sensor to Raspberry Pi and trigger actions based on distance (for now, it is using LEDs to know that it works).

Challenges

Mechanical:

• Still waiting on delivery of a few components
• 3D print fails

Electrical:

• Robot lacks electrical components to wire to.
• Missing pins to make component connectors with.

Software:

• Finding a good way to connect multiple ultrasonic sensors and respond to the data knowing the direction of the obstacle.
• Accidentally melted one ultrasonic sensor

Plan for week 5

• Mechanical:
  • Mounting wheels
  • Working Catapult arm
  • Working latching mechanism

Electrical:

• Drive the base forward and turn
• Control the reset motor for the arm
• Control latching mechanism
• Continue electrical board assembly
• Wire electrical components as they are mechanically added to the robot

Software:

• Connect and read data from more ultrasonic sensors respond accordingly.
• Connect to the motors so we can start controlling the actuators instead of sample LEDs.
