Servo Robotic Arm

Mechanical Design

This arm was designed to be quick and simple while still looking decent as it was intended for use at team demonstrations. This ended up being both the best part and the worst part of the overall design. The model was completed within 2 weeks, but with the rushed design and questionable final fit of the parts, the arm was only able to function for roughly 20 minutes at a time.

Electrical Design

There are many issues with the design overall, the biggest being how cramped it is. But the design is very simple, uses the same battery as the team's rover and parts that I had leftover from previous projects. It takes in a 6S LIPO voltage and drops it to 6V for the servos, this 6v is then also fed into the Arduino so it can create its own 5V source.

Firmware Design

The original plan was to control the arm with a remote control linked through the NRF24L01 I added to both the arm and controller, time ran out and I made the decision to cut the ability to control it remotely. Instead the arm ran premade routines save as structs on the Arduino. Refer to the posts below for more info.
