Force Completion This Test can be saved and resumed later. Your answers are saved automatically. The following test includes a subset of questions to allow students to prepare for the format and style of questions that they may face in the nal exam. You will see that the questions include di erent types (mutliple choice, numerical data entry, matching, and jumbled sentences). You will see that there are some ROS questions that won't be assessed in this year's exam (this was done through the lab assignments), but as the purpose is to demonstrate examples of question format, style, and length that should be very valuable. Also note that di erent questions receive di erent amount of marks which scale with the question di culty and the expected time required to complete each question. Note that this mock only includes 6 questions as a sample whereas the real exam will include 20 questions. The mock question will remain available until Tuesday 1st June 09:00 BST - one hour ahead of the nal exam. You should be able to take the test repeatedly until Tuesday 1st June 09:00 BST. QUESTION 1 A battery-powered autonomous vacuum cleaner is used in a two-story home (that is, it has an upper and a lower oor). The vacuum cleaner takes 48 minutes of vacuuming time to clean the ‘top oor’ and 91 minutes of vacuuming time to clean the larger ‘lower oor’. The vacuum cleaner has an associated dock that is used to charge the autonomous vacuum cleaner. Before a clean starts the battery is fully charged to provide the maximum run time of 40 minutes. The robot factory settings state that if the robot has to return to the dock to recharge midway through a clean, then it should recharge for 120 minutes. The re-charge characteristics are provided in the following table: 12 points Save Answer Question Completi n Status: Click Save and Submit to save and submit.

Note that the automatic marking will only assign marks for an exact numerical match so check for typos. A. The total number of minutes required for the robot to vacuum the top oor is B. The total number of minutes required for the robot to vacuum the lower oor is As a graduate engineer, you are asked to reduce the total vacuuming time by optimised the charge time setting. C. What charge time in minutes (from those available in the table above) would you suggest using when cleaning the top oor? D. What would be the new number of minutes required to clean time of the lower oor if this setting was used? E. What charge time in minutes (from those available in the table above) would you suggest using when cleaning the lower oor? F. What would be the new number of minutes required to clean time of the upper oor if this setting was used?

Swarm robots are not well suited to miniaturisation Swarms robots have access to extremely limited computational resources and communication bandwidth. Swarms are less fault tolerant than single robot solutions Swarms behaviours must be based on similar behavours observed in animals in nature Swarms systems usually have less than 10 individuals The behaviours produced by swarms are due to non- centralised processes Swarm solutions produce inherently scalable solutions Swarms are generally made up of robots with a range of di erent morphologies 6 points Save Answer QUESTION 6 Th t f th ll i if th 2 points Save Answer Question Completion Status: Click Save and Submit to save and submit.
