A personal transporter is under development at LTH, Industrial Electrical Engineering and Automation, IEA. A wireless link is desired to develop control
remotely for the transporter. The development of the control becomes easier
without wires and if the transporter can move freely within the range of the link.
A link is built, using Bluetooth devices and a microprocessor from Microchip.
This link is able to carry an eight bit signal back and forth. The development
of the transporter has not reached a state in which it can receive or transmit
signals. Instead the link is tested with a signal generator and an oscilloscope at
rst and then for DC-motor control.
A test run is carried out with a signal generator and an oscilloscope. A signal
is created with the signal generator, which is fed to the microcontroller that
forwards the signal by a Bluetooth transceiver. Another Bluetooth transceiver
receives the signal at the remote site. The signal is forwarded to a computer
hosted control system, dSPACE, and a control signal is produced. The control
signal is sent back to the microprocessor by the Bluetooth transceivers and forwarded to an oscilloscope via a D/A converter.
