Suppose a differential drive robot starts at coordinates [ro, Yo, fo] = [0, 0, 0] in a 2D plane. It has a wheelbase (L) of 20 centimeters and a wheel radius (R) of 10 cen- timeters. The left wheel (v₁) and the right wheel (vr) rotate at a radians per second with a time step of 0.2 seconds. The applied wheel velocities are given for each timestep in the table. a) Write the discrete time forward kinematic equations for the given robot parame- ters. b) Calculate the robot's new position and orientation at the end of each time in- terval and fill the table using a discrete time update with a time step of 0.2 second.

2. Suppose a differential drive robot starts at coordinates [ro, yo, 0o] = [0, 0, 0] in a 2D
plane. It has a wheelbase (L) of 20 centimeters and a wheel radius (R) of 10 cen-
timeters. The left wheel (v₁) and the right wheel (v.) rotate at a radians per second
with a time step of 0.2 seconds. The applied wheel velocities are given for each
timestep in the table.
a) Write the discrete time forward kinematic equations for the given robot parame-
ters.
b) Calculate the robot's new position and orientation at the end of each time in-
terval and fill the table using a discrete time update with a time step of 0.2 second.
