is the quality of the optics, and Navya is working with a range of suppliers on higher quality camera modules. Other sensing technologies such as radar and ultrasound have not been used so far but are under testing by Navya, which is also investigating adding other sensors on the sides of the ARMA to better sense the position of vehicles or pedestrians around it. Physical deadlock A unique aspect of the platform is a physical deadlock for safety. The current from the battery is used to hold open an electromagnetic lock: if the current fails, the lock closes on the motor shaft and the vehicle stops as quickly as possible, as the sensors and computing controller will have failed as well. Navigation Navigation is handled by a GNSS chipset with an RTK (real-time kinematic) addition. This uses a controller that also has a GNSS receiver at a specified location to transmit error-correction data to a GNSS receiver on board the ARMA. A 3G mobile phone link, using an industrial module coupled with virtual private network software, is sufficient to provide a secure connection, as an open connection would allow a hacker to transmit different error data and divert a vehicle. This system supports vehicles operating up to 20 km from We want all the information to be in one format for analysing it in the same way. If it is not consistent then the vehicle will operate in a safe, degraded mode
