A local school for the handicapped wanted to expand their
training and rehabilitation program to water sports. They
had adapted an existing joystick controller to work with two
electric propellers, but wanted to add a half-speed control
and a remote joystick so that an on-board trainer could take
control in an emergency. |

System Overview
Bolton Engineering designed a new controller to add the
half-speed function and allow for a remote joystick. Both
are packaged in water-resistant boxes. The controller and
joystick features:
- Two 300 Watt PWM motor controllers (13.8 Volts at up
to 24 Amps) using power MOSFETs.
- Ten hour battery life on a single charge.
- Quick-disconnect battery connectors for rapid battery
changeover.
- Low-battery detection and alarm.
- Remote joystick.
- Half-speed setting.
Results
The school has used the prototype controller for over
a year. Bolton Engineering has since built two additional
units for other schools.
- “Most of the children have never been in a canoe
before... the sense of freedom and power they experience
is tremendous." - Trainer.
- "The look the kids have on their face out on the
water is incredible..." - Administrator.
Project Scope
Bolton Engineering was responsible for schematics, circuit
board layout, testing, documentation, and manufacturing.
One controller was supplied to the school in 1990 and another
two in 1991. |
