1. Robot Hand Building 2. Robot Arm Project Agenda 1/17 1. Robot Hand Building 2. Robot Arm Project

Robot Hand Building To learn about how to mimic human- like kinematics with machines, follow the plans to build a robot hand Work in groups of 2-3 30 min for construction Think of how this works like a real hand

Robot Arm Design Project Final grade of the course (counts as a test grade) In groups of 3-4, your task will be to create a robot arm that can complete a specified task. You must: Work out a detailed design on paper Research may be done to help brainstorm Select parts and build a prototype Test the prototype for function Redesign to make improvements Continue this cycle as many times as you can by Friday.

The task Your Mech Tech teacher is too lazy to pick up a cup and bring it over to drink from, so he hired your engineering firm to design a robot to accomplish this task. The design specs are: The arm must be at least 18” long. The arm must be able to pick up a styrofoam cup and bring it to you The materials cost of the arm must be within “$50”

Materials Cost (you may return items if unused) Price per Unit Hangers $5 ea. Cardboard strips $4 ea. Fasteners 50 cents ea. Binder clips Pencils $1 ea. Twine / fishing line $1 / ft. Rubber Bands Paper clips Clothespins Popsicle Sticks Straws

Grading (out of 50 points) 35 points – 2 completed design cycles 40 points – 2 completed design cycles with 18” minimum arm, cup grabbed OR within budget 45 points - 2 completed design cycles with 18” minimum arm, cup grabbed AND within budget 50 points - 2 completed design cycles with 18” minimum arm, cup grabbed AND within budget, as well as consistent smooth operation of device

Bonus: If successfully completed, you may try to improve your arm by: 1. picking up a weighted cup (5pts/500g) 2. Motorizing your robot (by rigging to lab motors and winches or pulleys) 3. 5 extra points for group in class with working project from the lowest budget

Planning You have three days to complete this. You should plan to begin testing on the second day, in order to give you enough time to redesign (that means day one should be the initial design and build).
