Robotic Arms Libraray
HW 1 - DH Parameters & Direct Kinematics
1. Define the DH Parameters of ALL the robotic systems in the library in tow methods (a) modified form as discussed in class and (b) standard form
2. Define the homogeneous transformation matrixes (modified form only)
3. Derive the Direct Kinematics explicitly / analytically and defining the homogeneous transformation matrix (base to tool) – You may use Matlab to do so.
4. Using the Matlab’s Robotic toolbox plot the figures of all the robotic systems in the library
5. Submit the Matlab source code along with your solution

HW 2 - HW 2 Solution - Inverse Kinematics
Derive the Inverse Kinematics of each robotic arm in the library using two methods:
(1) Geometric Approach
(2) Analytical Approach.
Define an expression for each DOF and explain / sketch the multiple solutions.
Note that each angle must be define using the function Atan2(*).
HW 3 - HW 3 Solution - Jacobian
1. Derive the Jacobian matrix for each robotic arm in the library using three methods and expressed them all in frame 0. Note that once the Jacobian is expressed in the same frame (e.g. Frame 0) the expression is the same regardless of the method used to derive it.
(a) Direct Derivative (Expressed in Frame 0)
(b) Velocity Propagation (Expressed in Frame N)
(c) Force Propagation (Expressed in 0).
2. Calculate the determinate of the Jacobian and define the singular configurations of each arm. Note that there might be more than on singular configuration.
3.
Sketch the singular configurations.
4. For the RRR arm in the libraray draw the linear and angular velocities similar to the example shown in class.
HW 4 - HW 4 Solution - Dynamics
For the versions of the 2 DOF arm presented in class derive the equations of motion using the alternative method. For the first version in which the CM is located in the joints use the Lagrange method. For the second version in which the CM is located in the middle of the link use the Newton-Euler method.
For the Manipulator 3D-1-RRR derive the equations of motion using the two methods. Assume that the CM for each link is Lci units of length from the joint.
