After integrating all the electronic parts like the Arduino Uno Rev. 3 into the LEGO robot we went back to the Deutsches Museum München to test the whole installation for a second time. During our first test with museum visitors we recognized some unwanted behaviours with our gesture controlled robot:
- People tried to control the robot using only one hand
- The other hand was holding a jacket since it was winter
- Maybe for them it was way more intuitive to use one hand only
- Solution: Implement one hand gesture control
- Connection problems with our XBee module
- We had several issues when using a TCP connection
- Solution: Send data about robot movements using UDP
- The robot drifted off to the right
- Electric motors can move at different speed when receiving the same voltage
- Solution: Send different voltages to the electric motors for getting the same motor speed (“trimming”)
We still have to work on a final design for the showcase. Here you can see a short video demonstrating the exhibiton project.
