Agenda

• 1. What works?
• 2. What was hard to get working?
• 3. What will work?

What works?

❏ Own Android app ❏ Bluetooth connection to Myo ❏ Gesture Parsing

What works?

❏ Connection to Bluetooth shielded Arduino ❏ Setting pins with open source vendor app ❏ Control servo motor and read light sensor

What was hard to get working?

Problem: Myo Android SDK reached version 0.10.0 ⇒ Problems with gradle (building from maven) ⇒ Doesn’t build with Android SDK Version 23 (latest) Solution: Manually assembling complete android project, build files and libraries.

Github: https://github.com/FHorschig/MyoRobotArm

What was hard to get working?

Problem: RustyRobots “Greifarm” not existent anymore (and template seems to be flawed) Solution: Prototype a simple replacement with lego. (Also: free gears)

What was hard to get working?

Problem: Make weak servo motors move heavier arm. Solution: Gears ⇒ Worm drive to huge rack-wheel (If Power doesn’t suffice: 9V Block can power servo using an h bridge)

What will work?

❏ Connect myo-phone-app and phone-arduino-app ❏ Wire robotic arm up with motors ❏ Add (pressure) sensors to arm ⇒ stop autonomously

Wrap up

❏ Connection myo to phone ❏ Connection phone to arduino ❏ Connection myo to phone to arduino ❏ Electronic works ❏ Robotic arm works ❏ Electronics attached to arm ❏ Reaction to pressure

Project works according to time plan?

Kind of, yes.
