Progress Report, February 11, 2011.
- I am currently working on determining the feasibility of this project. To do this, I have done the following:
- Determine the maximum velocity of the mobile platforms.
- I found the maximum forward radial velocity was 7 rad/s. The max backwards radial velocity was 8 rad/s.
- This translates to a maximum forwards and backwards velocity of 0.35 m/s and 0.4 m/s respectively.
- Image of .vi used to find radial velocity.
- This result is lower than hoped. We were expecting a velocity of around 1.0 m/s.
- Set-up of Ultrasonic Transmitter and Receiver
- Setting up the transmitter and receiver proved harder than expected. With help from Ed Richter, I got a .vi working that could run both the transmitter and receiver on the same Elvis board. However, there was an issue of the signals being mixed somewhere between the board and the computer; even if I had the transmitter unplugged, the receiver would still show a strong peak at the frequency the transmitter was programmed to transmit (40khz). So, my temporary solution is to run the receiver and transmitter on different Elvis boards (each of which is connected to a different computer). This works, but is not the most practical solution, so work will have to be done in that regard.
- Determine the maximum velocity of the mobile platforms.
