Robotic Arm: Team Roaring Bears
Team Roaring Bears' Robotic Arm
The Roaring Bears constructed a fairly simple arm of total length 44 cm.
They modeled it in SolidWorks using mostly pre-drawn parts, with some additions included, such as the first servo bracket and the pencil holder.
Overall, it was highly successful. It was incredibly smooth-running, despite initial 'junkie' behaviour. However, a lingering problem is the arm's tendency to skew drawings - circles become eggplant-shaped, lines are curved, et cetera. A fix for this is in the works.
