The main mechanism in the spacecraft is the Antenna deployment mechanism. The mechanism is similar to that flown successfully on the Xatcobeo CubeSat.
The mechanism system holds the antennae in their launch/stored positions under the tension of a nylon thread passed over a resistor. When deployment is required a resistor burns through the nylon wire. The antenna are sprung and deploy by themselves once the retaining wire has been severed.
The UoS3 project is undertaken with the support of the Education Office of the European Space Agency, under the educational Fly your Satellite! Programme; an ESA educational programme complementing academic education.
