Frequently Asked Questions

Emergency Braking System

Why are you using a pneumatic actuator for the braking system?

If we need a force of 100 kgf at a speed of 0.5 m/s the power requirement is roughly 500 W. An electric actuator capable of that is bulky and hard to source. A cable and pulley system with a motor and pressure feedback was considered, but cables cannot bend sharply. Since we already have a pneumatic piston from our sponsor Festo, it is the simplest solution.

Battery

Why is the battery placed at the back?

The rear of the kart offered the most practical space for such a large and heavy component. Because the seat, wheels and pedals remain in their original positions, placing the pack behind the driver was the best compromise. Handling is less of a concern since the kart will usually run autonomously without a driver's weight.

Motor choice

Why not use a thermal engine?

A combustion engine would add unnecessary complexity such as fuel, exhaust and cooling. Electric motors require little maintenance and are simpler to control electronically. Since this prototype focuses on sensors, actuators and software, the type of engine does not matter as long as the vehicle moves when throttle is applied.
