Handle 40 amps of continuous current for motor output Operate in normal room temperatures of 15 degrees Celsius to 32 degrees Celsius 2.3.2.3 Sensor Aggregation Hardware The sensor aggregation hardware is responsible for interpreting the data from the sensors and converting it into useful data for the central processing unit. The sensors that the aggregation hardware is responsible for interpreting include the four encoders measuring the lateral position of the AI opponent and the four encoders used to track the lateral position of the human controlled puppets. The aggregator takes in the encoder data and converts it to a serial output to be read in by the computer. Summary of requirements: i/o ports for 8 optical quad encoders 1 serial output port for computer interface 2.3.3 Actuators In order to meet the design requirements of a semi-automated foosball game that is challenging to an average user, the system must be built with high-quality and mechanical subsystems. In this section the design requirements and specifications for mechanical actuators are analyzed. Prior studies have shown that an accurate estimate for the maximum speed of a foosball during a regular match is 10 meters per second . Using this value and relevant dimensions from a regulation foosball table, the minimal necessary response time and speed of the actuators can be computed. Following is a diagram of a standard foosball table. The colored ovals are the position of the puppets, with colors corresponding to each This project will control four of the rods (one player) player’s team. in both the linear direction and the rotational direction. The dimensions are 120cm table’s long, 68cm wide, with a range of 8 cm to 15 cm perpendicular distance between rods. The goals are 20 cm wide. Each player controls thirteen players on four rods. Figure 2.3.3.1: Relevant dimensions for calculating actuator response times Lateral Motor Requirements From the measured dimensions of Figure 2.3.3.1 and the speed of 10 meters per second as an approximate maximum speed for the ball, the speed that will be required to move in the lateral direction can be computed. This value will ensure that the electric motors used in the automated foosball table will be able to keep up with the gameplay. However, the requirement calculated for the motors using ideal values is unrealistic to actually
