Meet The Robots

SmallSizeHolland’s robots are the result of years of design, innovation, and development by a multidisciplinary team. So far there have been four generations of robots which have been worked on.

Gen4

SmallSizeHolland is currently working on the Gen4 robots. During the development of the Gen3 robots the electrical engineers focused on modularity whereas for Gen4 it is up to the mechanical engineers to focus on modularity. The ultimate goal regarding modularity is being able to replace any part within five minutes.

Generation 4

The hood also got a redesign by the industrial product designer. Instead of using metal hoods like the three generations before, the hood is now made out of plastic in order to reduce weight. Furthermore, the dribbler, the kicker and chipping device are being reworked by the mechanical engineers in order to improve ball control.

Generation 4

Gen3

While working on Gen3, for the first time in the history of Small Size Holland, some mechanical engineers joined the team. This allowed Small Size Holland to completely redesign the robot. The robots changed to a four wheel robot instead of a three wheel design. The hood also got redesigned to be almost twice as light as the Gen2 hood.

Generation 3

The electrical engineers also made the robots more modular, making it easier to repair robots. In Gen3 custom solenoids were implemented. The mbed from Gen2 robots got switched out for a custom micro-controller with a dual core processor and FPGA. The robots also switched to WiFi for communication instead of NRF. The main reasons for SSH to switch to WiFi are: communication via WiFi has a lower susceptibility to breakdowns and communication via WiFi holds more possibilities for modification than NRF. WiFi also allows Small Size Holland to do TCP for guaranteed delivery of messages such as settings or even firmware upgrades.

Generation 3

Gen2

During the development of Gen2 robots an electrical engineer joined the team. This allowed the team to create a custom motherboard for the robot.

Generation 2

The team also added a chipper to the system and built the dribbler motor in the dribbler itself. Gen2 robots are powered by an mbed. The Gen2 robots started using the iconic Small Size League hoods.

Generation 2

Gen1

Gen1 was a try-out to see if it was feasible for Saxion to compete in Small Size League soccer. Gen1 was made entirely by a group of applied computer science students. The robots were made mostly out of 3D-printed parts and the robots communicated via radio-frequencies (NRF). The Gen1 robots had a kicker and dribbler but lacked a chipper.
